Description

(54) Coating for waterproofing purposes

The invention relates to a covering covering for waterproofing purposes and to a method for its construction and treatment for the building industry.

Existing coating coverings include buff asphalt strips glued with hoppy asphalt, or rubber strips and PVC - weather-resistant foils, possibly also glued. The disadvantages of these coverings are, on the one hand, the lack of the necessary materials and, on the other hand, the lengthy method of construction, particularly when using hot asphalts, and its dependence on weather conditions.

These drawbacks are overcome by the coating of the present invention and the method of making and modifying it. This covering for waterproofing purposes comprises a sealant based on vinyl chloride-vinyl acetate copolymers according to the author's certificate No. 187 896 and is based on the composition of alternating layers of said sealant and strips or sheets of plastomers or elastomers and preferably not stabilized against aging or In the case of textile, glass or synthetic fiber structures, the outer and lower layers of the composition each comprise a sealant, optionally surface-treated on the outside or inside, containing the heat-insulating filler material and the strips, foils or sheets are surrounded by the sealant.

As the plastomer foil, for example, polyethylene, polypropylene and polyvinyl chloride foils can be used, as elastic belts of rubber belts of various kinds of rubbers,

For example, poly (butylene), ethylene (propylene) and the like can be fabricated from textile, glass or synthetic fibers. As thermal insulation filler material, | foam materials, whether in granules or in shaped profiles.

In order to accelerate and further mechanize the waterproofing covering according to the invention, the covering covering is adapted to the shape of a prefabricated panel of suitable size on a rigid support layer of fibrous mineral or organomineral plates and the upper edges of the panel are provided with adhesive or self-adhesive tape.

The foils or strips are sandwiched between the layers of sealant to be applied to the backing layer to be insulated at a thickness of at least 2.0 mm, and then the foils or strips are alternated with the sealant layers and inner layers as required optionally, heat-insulating filler materials are embedded in the sealant, whereby the final outer layer is optionally surface-treated, for example with loose aggregate or cladding materials. The intermixing of the sealant layers with films or strips of non-aging plastomeric or elastomeric materials allows the formation of a well-stabilized weather-resistant covering, which in addition is more cost-effective by using unstabilized components and proves the same service as more expensive materials.

The specific embodiment of the covering and the elements will be explained by means of the examples shown in the attached drawings, which, however, do not limit the scope of the present invention.

Example 1

FIG. 1 is a vertical sectional view of a non-aging stabilized anti-aging polyisobutylene rubber sheet 3 embedded in a layer of sealant 2 with a backfill of graded aggregate 4.

Example 2

Fig. 2 is a vertical cross-sectional view of a composition made of two layers of PVC foils 2 for more demanding coatings, inserted again into the sealant 2, the surface treatment preferably being of ceramic materials 6.

Example 3

Fig. 3 is a cross-sectional view of a composition formed from a foil 2 adhered to a sealant coating 2 and covered with two layers of sealant, the backing layer 6 being made of a sealant filled with thermal insulating materials, e.g. foamed foam granules

216 495 polystyrene and the top layer is coated with sorted aggregate The substrate 1, consisting of either an aged coating or concrete or other hard construction material of the middle sheath, is applied with a sealant 2 at least 2 mm thick, on which the polyethylene foil 2 is applied. , reinforced with a textile insert with a total thickness of about 0.2 mm. Subsequently, the film 2 is again covered with a sealant 2 having a thickness of at least 3 mm, into which the sorted dry aggregate 4 with a grain size of 2 - 8 mm is immediately poured, or preferably concrete and ceramic cladding materials g can be placed in the sealant 2.

In order to increase the protection of non-stabilized polyethylene films against thermal stress, the glued film 2 is covered with a heat insulating layer of sealant 6 filled with a heat insulating material, for example foamed polystyrene granules, and this heat insulating layer 6 is covered with another sealant layer 2 with an aggregate surface

Example 4

Fig. 4 shows a top view of the covering panel, wherein 1 denotes a carrier layer, e.g., an organo-mineral layer, 2 is an edge adhesive tape provided with a protective film 8, for sealing the joints of the individual panels with similar adhesive tape; a cross-sectional view of a workpiece is shown. The backing layer 1 is provided with a sealant layer 2 on which a plastic film strip 2 is provided with a heat-insulating sealant layer 6 on the edge 8 with an adhesive tape 2 provided with a protective film 8. These parts ae can be manufactured factory or outpatiently in larger sizes. eg 120 x 240 or 120 x 300 - 350 cm for a total thickness of 1-3 cm depending on the carrier layer used. These panels allow immediate coverage of thermal insulation layers of any type, even by non-specialized personnel.

This eliminates the risk of wetting the roof structure during rain, and also allows roofing at low temperatures. The edges of the panels are modified so that the covering of the individual panels can be carried out even in rain or frost by using adhesive strips of the same kind as the panels of the covering.

With various assemblies of waterproofing putty and prefabricated supporting foils, strips, sheets and thermal insulating materials, it is possible to create completely new types of thermal-waterproof roof cladding suitable also for the subsoil of garden and decorative areas on the roof, possibly for water reservoirs, etc. method for pressure ground insulation against water.
