GREENING SYSTEM AND METHOD FOR CREATING A GREENING SYSTEM

description

The invention relates to a greening system, in particular a lawn and / or green roof and / or extensive greening system

Claim 1. The invention also relates to a method for producing a greening system, in particular a lawn and / or lawn

Roof greening and / or extensive greening system according to claim 16.

Plants are usually grown in standardized growing pots with an or

multiple irrigation and root growth openings, also called

Culture pot slots are designated, cultivated and marketed. Earth plants are usually left in their growing pot and placed in a pot or planted in a sub-irrigation system using plant substrates.

The increasing sealing of areas in open spaces through, for example, building developments, area densification, urban developments, roads and

Pavement construction arouses the desire to simply,

Greening them inexpensively and without complex construction work.

In particular, there is a growing desire for greening buildings through roof greening of flat roofs, roof terrace greening,

Facade greening, terrace greening, balcony greening,

Greening of courtyards, as well as room greening with wall greening and

Green corner systems.

Often, roof areas are extensively greened. On the existing

Clay granules are spread over the entire roof waterproofing. A drainage mat is then laid on top of it, with the area above the drainage mat being filled with plant substrates. After that they become flat Planted ground cover, perennials, moss, etc. This leads to an additional large load on the roof.

Furthermore, due to these planting surface structures, after a long time there is regular root compaction combined with a low air supply in the root area and the associated root rot, which often leads to an extensive loss of greenery. There are also broken or sick ones

Due to the root compaction, planting areas are very difficult and time-consuming to remove and replace.

In addition, conventional roof planting systems are associated with associated drainage problems. Accordingly, slopes often have to be formed on roof surfaces so that excess water can run off.

In addition, the problem with known roof planting systems is that, depending on the planting selected, the roof must also be supplied with large amounts of water. Roof planting systems without an additional irrigation system often accept that the plants, especially the planted vegetation cover, will dry out. In addition, these green roof systems often lead to damage to the underlying flat roof coverings and to corresponding damage due to the root compaction

Structural damage. Repairs are often only possible by completely removing the vegetation and are accordingly labor and cost-intensive.

In recent years, football pitches that were equipped with natural grass have also increasingly been replaced by artificial turf pitches. According to studies, however, it has been shown that, due to these artificial turf pitches, a total of around 11,000 tons of microplastic enter the environment unfiltered and the food chain via the groundwater. This is the third largest source of plastic particles.

Accordingly, the desire for natural grass pitches will increase again in the future. However, the turf should have approximately the same load-bearing capacity as the artificial turf. This increases the requirements for corresponding greening systems with regard to constant irrigation and with regard to the planting situation in connection with the avoidance of

Root compaction, etc. From the above, the object of the present invention arises, according to which a further developed greening system, in particular a

further developed lawn and / or green roof and / or extensive greening system should be specified.

On the one hand, the greening system, if this is a

The green lawn system is designed, good conditions in

In connection with lawns, such as those used on soccer fields, for example. In addition, rainwater, especially the large amount of rainwater in a downpour, should be able to drain off quickly with the help of a further developed greening system.

Waterlogging should be avoided in this context.

On the other hand, green roof systems in particular should have a structurally simple structure so that additional roof loads generated are reduced. In addition, this greening system should be able to be supplied or operated with a relatively small amount of water.

Another object of the present invention is to provide a further developed method for producing a greening system, in particular a further developed lawn and / or green roof and / or extensive greening system. The process is also intended to be used in terms of retrofitting or modernizing an existing one

Be well applicable.

The above-mentioned task is achieved by a greening system, in particular by a lawn and / or roof greening and / or extensive

Greening system, solved, wherein at least one module unit is arranged in a water basin and the module unit has at least one frame, preferably stabilizing elements, and at least one membrane element, the membrane element being formed on or on the frame and the frame having recesses at least in sections on the bottom side, so that the module unit by means of the recesses in such a way

Water basin is positioned or positionable that a water circulation and between the water basin floor and a through the frame and the

Membrane element limited vegetation space is formed. In one possible embodiment of the invention, the greening system comprises at least one water basin and at least one

Modular unit. A plurality of modular units are preferably arranged in a water basin. If several module units are arranged, these module units are preferably designed in the same way. This has the advantage that the

Modular units can be variably combined, in particular variably expandable.

The water basin and the at least one modular unit are different components that are preferably not permanently connected to one another. The water basin and the at least one module unit are preferably separate components. The at least one modular unit is preferably only on the bottom of the water basin or the

Water basin floor placed, but not firmly connected to the water basin and / or the water basin floor.

It should be pointed out that water is also to be understood as an aqueous nutrient solution or a water-containing nutrient solution or water mixed with nutrients.

A module unit has at least one frame, preferably with

Stabilizing elements.

The modular unit, in particular the frame and / or the stabilizing elements, can be formed from metal, preferably from steel, particularly preferably from stainless steel, or from plastic. In particular, production is over

glass fiber reinforced plastic possible.

In one embodiment of the invention, it is possible that the frame is formed from individual frame elements. The frame elements can be formed from plastic and / or metal and / or metal alloys and / or fiber-reinforced plastic. It is possible for the frame elements to be arranged in a rectangular, in particular in a square, basic shape with respect to one another.

The frame can in particular be such a frame which is formed from four sheet metal segments. These four sheet metal segments can be in the form of a rectangle, in particular in the form of a square, be arranged to each other. In particular, these sheet metal segments can be welded to one another.

In a further embodiment of the invention, it is possible that a frame of the module unit is formed from a single sheet metal segment. The

Sheet metal segment can form a rectangular, in particular a square, shape by forming three bending points. The two ends of the

Sheet metal segments can be connected to one another, in particular welded to one another.

Furthermore, it is possible to produce several frames using plug-in elements, in particular using plug-in sheets. A plug-in element, in particular a plug-in plate, has connection zones which are spaced apart from one another in the longitudinal direction, for example. A connection zone has at least two slots arranged one above the other in the vertical direction. A support element is formed between the slots due to the remaining material. The lower slot is preferably made longer than the upper slot.

Two plug-in elements with such connecting zones can be plugged into one another with the aid of such slots. The upper plug element rests with its support element on the support element of the lower plug element.

In general, if a frame is designed with a square basic shape, four frame elements, in particular four sheet metal segments, can be manufactured in the same way.

In addition, square frames, and thus square modular units, are easier to combine and a greening system can be expanded more easily.

The frame, in particular the individual frame elements, particularly preferably the sheet metal segments, has / have recesses, at least in sections, on the bottom side facing the water basin bottom.

In a preferred embodiment of the invention, the frame has recesses in sections on all frame elements, in particular on all sheet metal segments. The recesses can for example be designed as rectangular or semicircular or triangular material recesses. The recesses on the bottom side of the frame are preferably designed in such a way that the recesses are arranged in alignment with one another on opposite frame sides, in particular in the case of opposite frame elements. This enables particularly good water circulation, since the water flowing through the recesses on one side of the frame is not blocked in the course of the flow due to an opposing frame element.

The water basin preferably has an overflow system with the aid of which a certain water level can be set in the water basin. The recesses preferably have a height such that this height is less than the set or to be set water level.

Furthermore, it is possible that an overflow system is designed in such a way that the water level can be variably adjusted. For example, a water drain could be designed to be adjustable in height. A water drain is preferably adjustable in height such that the water level can be set variably.

Adjustment of the water level is particularly important with regard to different growth and regeneration phases as well as the vegetation cycle

Lawn and / or green roofs are advantageous. It is possible in one

Set the water level higher during the growth phase than, for example, during dormant vegetation.

The overflow system of the water basin is preferably designed in such a way that a water level of 1 cm - 30 cm, in particular 2 cm - 25 cm, in particular 3 cm - 20 cm, particularly preferably 3 cm - 4 cm, is set.

The water basin is furthermore preferably designed in such a way that a maximum basin depth of 40 cm, in particular 30 cm, in particular 20 cm, in particular 15 cm, in particular 10 cm, is formed.

Due to the shallow pool depth and / or the low water level of the water pool, no high additional roof loads are generated. With the help of the modular unit it is possible to create a vegetation cover in the

To use water basins. Such a vegetation cover is preferably a lawn and / or greenery. When

Vegetation cover are, for example, lawns or grass areas or rock garden areas or moss areas or areas

low-growing plants, such as houseleek, are possible.

A module unit preferably has at least two stabilizing elements. The stabilizing elements can, for example, be designed as diagonal struts and / or arranged like a grid.

A diagonal strut is to be understood as a strut of this type which runs from one corner of the frame to an opposite corner of the frame. When the frame is designed with a rectangular, in particular a square, basic shape, the stabilizing elements run in the

Training as a diagonal strut thus crossed to one another. It is possible for the stabilizing elements to run on the diagonals of the frame when a diagonal strut is formed, but are spaced apart from the corners of the frame.

With a grid-like arrangement of the stabilizing elements can

at least two stabilizing elements can be formed perpendicular to one another. In such an arrangement, the stabilizing elements preferably form a cross shape. It is also possible that at least three

Stabilizing elements are formed in this arrangement.

The stabilizing elements can for example be designed as tubular elements. This is used for a particularly simple and inexpensive construction.

In a further embodiment of the invention it is possible that the

Stabilizing elements are designed as sheet metal segments. Such an embodiment of stabilizing elements is particularly advantageous if the frame elements of the modular unit frame are also formed from sheet metal segments. It is possible for the stabilizing elements to be designed as curved sheet metal segments. The bent sheet metal segments can have a U-shape with flange segments located thereon. Such sheet metal segments form a type of foot or feet. Unless the stabilizing elements are curved

Sheet metal segments are formed, the stabilizing elements

for example, be arranged in a pattern on the membrane element and attached to this.

With the help of the selection regarding the position and the number of

Stabilization elements, a stiffness or resilience of the module unit can be adjusted.

Furthermore, it is possible that the stabilizing elements are designed as plug-in elements, in particular as plug-in sheets. This embodiment is particularly advantageous if the frame (s) is / are also formed from plug-in elements, in particular plug-in metal sheets.

The stabilizing elements can be attached to the bottom of the pool

facing sides have recesses. In particular, such stabilizing elements, which are designed as sheet metal segments, have recesses. This ensures that if the stabilizing elements are the same as the frame and / or if the stabilizing elements are designed in such a way that they have the same bottom-side plane as the frame, that the water circulation is not due to the stabilizing elements

is affected.

The one formed between the water basin floor and the module unit

Vegetation space is preferably formed by a water level formed in the water basin and an atmosphere area formed between the water level and an element of the modular unit.

A substantially sealed vegetation space is preferably formed, with an atmospheric area extending to the outside through the module unit and / or through the frame of the to form a climatic zone below an element covering the frame and above the water surface

Modular unit and / or by a horizontal element of the modular unit, is closed / enclosed in particular by a membrane element and / or by a border of the water basin.

The vegetation space that is formed is partially decoupled from the environment, which reduces the air exchange rate between the vegetation space and the environment. Air exchange with the atmosphere is therefore mainly only possible via a membrane element and thus directly in the area of the plant's root system. On the one hand, this ensures a good growth climate in the

Vegetation area with high humidity, and on the other hand it prevents unhindered evaporation of water or aqueous nutrient solution from the

Vegetation space directly to the outside.

The water or the nutrient solution remains under the modular unit, in particular under a horizontal section of the modular unit, and is deposited there

Evaporation on elements of the module unit, in particular on one

Membrane element, and drips back into the water basin. Of the

Compared to conventional planting systems, water consumption can be sustained and reduced by up to 80% and the otherwise necessary watering intervals can be extended significantly. Casting periods can be extended significantly. This saves staff and / or administrative costs.

Due to the arrangement and / or dimensioning of the stabilizing elements, the resilience of the module unit can be set or adjustable in a further embodiment of the invention. The rigidity of the module unit can be increased with an increasing number of stabilizing elements, in particular those that can be plugged in. This makes the module unit more resistant to treading.

With an increasing number of stabilization elements per unit area and / or with an increasing material thickness of the stabilization elements, the resistance to treading and consequently the rigidity of the module unit can be influenced.

In particular for the embodiment of the invention, according to which the

The greening system is designed as a lawn greening system, the lawn greening system can be specially set for the respective area of application. For example, it is possible provided that

A green lawn system is to be installed on a golf course, this with a high level of tread resistance of the module units or the module units accordingly hard. If the green lawn system is used, for example, in connection with a soccer field, the springiness of the lawn could be adjusted to be softer.

The greening system furthermore preferably comprises a membrane element which rests in or on the frame, the membrane element preferably being designed to be exchangeable and / or as a perforated plate and / or as a grid. The membrane element preferably forms an upper side or a cover side of a module unit. In other words, the membrane element can

Complete the module unit on the cover side, which can also be referred to as the ceiling side.

The membrane element can also be designed as a mesh, in particular a stainless steel mesh.

The module unit is preferably designed without a bottom. In other words, the module unit does not have a floor. As soil is such a

preferably a closed section to be understood, which forms a lower side or a bottom side of the module unit. Such a lower side or

The bottom side is preferably not formed.

This has the advantage that the modular unit is formed from a few components and can be installed in a water basin in a simple manner. Furthermore, the modular units do not necessarily have to be arranged and / or aligned exactly to one another, since water circulation is simply created through the water basin and the recesses formed in the modular units.

The frame of the module unit is preferably positioned or can be positioned with the bottom side of the frame on the bottom of the water basin in such a way that the module unit forms water circulation by means of the recesses in the frame. At the same time, between the water basin floor and the

Membrane element formed a limited vegetation space. A bottom side of the module unit is therefore not present separately, but only when it is positioned in the water basin. The bottom side is formed by the water basin or by the water basin floor, which is a different component or element. The water basin and the module unit are preferably separate components.

The membrane element preferably forms the upper horizontal section of a modular unit on which the water or the water evaporates

Nutrient solution accumulates. In other words, it becomes the one described above

Vegetation space is particularly preferably formed in the space formed by the modular unit between the frame surfaces and the membrane element.

In one embodiment of the invention, it is possible for the frame to be designed in one piece with the membrane element. In other words, it is possible to form both the membrane element and the frame from one component. For example, it is possible to reshape and / or bend the membrane element on the sides in such a way that the reshaped or bent sides form the frame element. It is possible to reshape or bend the membrane element on two opposite sides. Furthermore, if the membrane element has a rectangular basic shape, it is possible to bend or reshape the membrane element on all four sides. For this purpose, a recess or a groove is first made in the corners of the membrane element, so that the sides can be bent or reshaped.

With a possible one-piece design of the membrane element and the frame, the membrane element is preferably formed from a grid or a perforated plate.

A nutrient layer, in particular a granulate layer, can be located on the membrane element, the nutrient layer preferably being a

Layer thickness of 2 cm - 40 cm, in particular 2 cm - 20 cm, in particular 2 cm - 6 cm, in particular 3 cm - 4 cm.

The granules can preferably be Zeostrat.

Depending on the thickness of the nutrient layer, the height of an overflow system of the water basin should preferably be selected. It has been shown that with a granulate height of 40 cm, the overflow system of the water basin is preferably set in such a way that a water level of 3 cm - 20 cm is set. In a particularly preferred embodiment of the invention, the frame can form a modular unit area of 0.25 m ^{2 to} 5 m ² , in particular of 0.35 m ^{2 to} 2 m ² , in particular of 0.5 m ^{2 to} 1 m ² .

The membrane element preferably has a material thickness of 0.5 mm - 3.0 mm, in particular 1.0 mm - 2.5 mm, in particular 1.5 mm - 2.0 mm. Such material thicknesses have proven to be particularly advantageous, since this material thickness ensures, on the one hand, that a substantially

sealed vegetation space is formed and, on the other hand, the lawn and / or green roof can be irrigated. Due to the relatively small thickness of the material, roots of the lawn and / or the

Roof greening through the granulate and the membrane element in the

Reach vegetation space.

In one embodiment of the invention it is possible for the frame to have a step-like membrane element receptacle on the inside, the membrane element resting flush in the frame, so that the frame and the membrane element form a flush ceiling surface.

The shoulder-like membrane element receptacle can be formed, for example, with the aid of additionally attached strip elements. Furthermore, it is possible that a frame element, in particular a sheet metal segment, is already shaped in such a way that a membrane element receptacle is formed.

The membrane element receptacle can also be designed, for example, as a groove and / or as a weld seam.

The shoulder-like membrane element receptacle is preferably designed in such a way that the membrane element is completely flush with the further frame parts or with the further sections of the frame elements, in particular the sheet metal segments. The formation of a flush cover surface has the advantage that the layers to be applied to the membrane element,

in particular the nutrient layer and / or the lawns or

Roof foundation layer, not exactly on each individual module unit

must be positioned, but that the layers to be applied further across the module units, i.e. across several modular units,

can be arranged. In a further embodiment of the invention, the greening system comprises a plurality of modular units, with a membrane element, ie a single membrane element, resting on the frame of a plurality of modular units. This embodiment has the advantage that it is not necessary to produce a plurality of membrane elements, but rather a single membrane element that is in the

Compared to the above-mentioned embodiment (one per module unit

Membrane element) has a larger area and is used to cover several modular units.

In a further embodiment of the invention, the greening system can comprise a water temperature control system, in particular a water heating system.

Such heating or heating of the im

Water basin located water instead that this also with

Outside temperatures below 0 ° C have a water temperature of 2 ° C - 5 ° C.

The water temperature control system is preferably integrated in a separate water tank. With the help of a separate water tank, the water basin can be supplied with heated water. Due to the possible circulation in the water basin, the heated water can circulate throughout the water basin, i.e. be distributed.

A water temperature control system enables, for example, a heated lawn to be made available on the basis of the greening system according to the invention. Such a heated lawn is particularly advantageous when the greening system is used in connection with a soccer field. The lawn does not have to be processed in a separate process and / or cleared of frost and / or snow in frost and / or snowfall.

The water basin is preferably designed as part of a water circulation system. The water circulation system further has a / the

Water tank, at least one feed line, at least one drain and / or overflow system, and at least one drain line. The water, preferably at a temperature, is transported from the water tank to the water basin via at least one feed line. The water can flow out of the water basin by means of the drainage and / or overflow system. The water can flow back into the water tank via the at least one drain line.

The greening system according to the invention makes it possible that rainwater, in particular the large amount of rainwater in a downpour, can drain off quickly. This is particularly advantageous in the case of football turf, since on the one hand long breaks in the game are not necessary to dry the turf and on the other hand the turf is not damaged due to waterlogging.

The rapid drainage is due to the fact that below the

Nutrient layer, especially below the granulate layer, the

Membrane element is formed. Due to the in the membrane element

formed openings, the rainwater can flow into the vegetation space of the modular unit. Due to an advantageously designed water circulation system, the rainwater can then be collected and stored in a / the water tank.

In a further embodiment of the invention, at least one film is arranged on the water basin floor. The slide can be a

Act plastic film and / or an insulating film and / or a root protection film.

This film is preferably welded to the bottom of the water basin.

In this regard, such a welding is meant, as z. B. in

Connection with bitumen sheeting is known.

The film can i.a. serve as a root protection film, so that the material of the

Water basin is not affected. Furthermore, such a film can serve as an insulating film, so that the water basin floor can be sealed with the aid of the film.

In a preferred embodiment of the invention, the frame, preferably the frame and the stabilizing elements, can have a height of 3 cm - 20 cm, in particular 3 cm - 10 cm, in particular 4 cm - 9 cm, in particular 8 cm. Such fleas of the frame and / or the stabilization element has proven to be particularly practical, since due to this frame height there is an overall good ratio between the water level that can be produced and the total height of the water basin and the greening system required for this. The water level is preferably 3-4 cm with a frame height of 8 cm.

The water basin is preferably made of stone and / or concrete and / or asphalt. These materials are particularly important when training the

Greening system as a lawn greening system advantageous.

It is also conceivable, especially when used as a

Green roof system that the water basin is made of metal or plastic. Furthermore, it is possible that the bottom of the water basin is formed by an already structurally existing horizontal surface. This is, for example, the roof area when training as a green roof system. In addition, vertical elements can be attached in this case so that a water basin can be formed.

In one embodiment of the invention, the greening system can be an extensive greening system, in particular an extensive

Green roof system. Extensive (roof) greening is subject to natural and seasonal factors

Vegetation developments and stock changes. For extensive

(Roof) greening low-growing plants such as mosses, succulents, herbs and grasses are used, which are relatively small

Mark maintenance effort.

Another secondary aspect of the invention relates to a module unit. This module unit is used in particular for use in one

greening system according to the invention.

The modular unit according to the invention has at least one frame,

Stabilizing elements and at least one membrane element, wherein the membrane element is formed on or on the frame and the frame has recesses at least in sections on the bottom side, a vegetation space delimited by the frame and the membrane element being formed. With regard to the inventive design of the frame and / or

Stabilization elements and / or the membrane element, reference is made in full to the previous explanations.

The above-mentioned object is also achieved by a method for producing a greening system, in particular a lawn and / or green roof and / or extensive greening system, the method comprising the steps: a) providing, in particular building, a water basin,

b) Setting a defined water level in the water basin using a drainage and / or overflow system,

c) Arranging a plurality of modular units in the water basin, a vegetation space being formed between a water basin floor and the modular units.

Furthermore, the method according to the invention can provide that recesses are or will be formed in the frame of the modular units and water circulation is established in the water basin.

Module units according to the invention are preferably used. With regard to the possible embodiments of the module units, reference is made to the preceding explanations.

In the following, exemplary embodiments of the invention are explained in more detail with reference to schematic drawings.

Show it:

Fig. 1 shows a possible embodiment of a modular unit

greening system according to the invention; and

Fig. 2 is a partial sectional view of an inventive

Greening system.

In the following description, the same reference numbers are used for parts that are the same and have the same effect. 1 shows the basic structure of a module unit 20. The module unit 20 has a frame 25 and stabilizing elements 30.

The frame 25 is formed from four frame elements 26. The frame elements 26 are essentially designed as sheet metal segments. The frame 25 is formed, for example, by welding the individual frame elements 26 to one another at the respective side edges 29. The frame elements 26, which in the present case are designed as sheet metal segments, are preferably formed from stainless steel.

According to the invention it is also possible that the frame elements 26 are alternatively or additionally connected to one another by means of plug connections.

The frame elements 26 have recesses 27 on their bottom sides 28, which at the same time form the bottom side 22 of the frame 25. The

Recesses 27 are semicircular in the example shown

Material recesses formed.

The frame 25 preferably has a square base area. This enables frame elements 26 of the same design to be used and connected to one another.

The stabilizing elements 30 are also shown. The

Stabilizing elements 30 are designed as diagonal struts. That is, the stabilizing elements 30 each run from a first corner to an opposite corner of the frame 25. In the present case, the corners of the frame 25 are formed by the side edges 29 connected to one another.

The stabilizing elements 30 are also designed as sheet metal segments. The stabilizing elements 30 have recesses 32 on their lower side 31. The stabilizing elements 30 are essentially designed in the same way as the frame elements 26. This in turn enables the modular unit 20 to be easily lowered.

The resilience of the modular unit 20 can be influenced by means of the arrangement and the dimensioning of the stabilizing elements 30. It is conceivable that further stabilizing elements 30, the ones already shown Stabilizing elements 30 also cut at the intersection point 36,

are trained. This would influence the resilience accordingly, so that the modular unit 20 is made correspondingly harder when a plurality of stabilizing elements 30 are formed.

On the inside 24 of the frame, i. a membrane element receptacle 35 is also formed on the inside of the frame elements 26. This

Membrane element receptacle 35 is formed as a step-like edge on which a membrane element can be placed.

The height of the membrane element receptacle 35 is based on the material thickness of the

Membrane element (not shown) adapted. An inserted membrane element preferably ends with the upper edge 34 of the frame 25, so that the upper edge 34 of the frame 25 is flush with the membrane element. Consequently, a flush ceiling surface of the module unit 20 is formed.

In FIG. 2, a section with regard to a greening system 10 is shown. In Fig. 2 only a section of a module unit 20 is shown. In fact, a greening system 10 preferably has a plurality of module units 20.

The greening system 10 comprises a water basin 15. The side elements of the water basin are not shown in FIG. 2. The water basin 15 is made of stone in the example shown.

A film 18 is formed on the water basin floor 16. This film 18 is preferably a plastic film with the

Water basin bottom 16 is welded. The module unit 20 is arranged on the water basin floor provided with a plastic film 18.

The module unit 20 is arranged in such a way that the side 22 of the frame 25 which has the recesses 27 faces the water basin floor 16. The recesses 27 are used for water circulation.

A vegetation space 70 is formed between the water basin floor 16 and the modular unit 20, in particular the membrane element 40. Of the

Vegetation space 70 corresponds to the distance between the membrane element 40 and the water basin floor 16 provided with a film 18 Vegetation space 70 is formed by the water level WP and one between the water level WP and the membrane element 40

Atmospheric area 80 is formed. It can be seen that the height H _{A of} the recesses 27 is less than the water level WP.

The height of the frame elements HR is preferably 8 cm. With such a design of the frame 25, a water level WP of 3-4 cm is preferably set.

A nutrient layer 50 is preferably located on the membrane element 40, which preferably has a material thickness Ds of 0.5-3 mm

The nutrient layer preferably has a layer thickness D _N of 2-6 cm.

A lawn area 60 is in turn formed on the nutrient layer 40. In the example shown, the greening system 10 is a

Green lawn system. Alternatively, it is possible to do an extensive one

Produce a green roof system by means of the greening system 10 according to the invention.
