In the building industry, the water and moisture barrier A and / or water vapor barriers are of great importance because although they only account for about 1 % of the building costs, they have to be extremely reliable because failure cannot be accepted. The severity of the requirements and the possible penalties for errors naturally depend on the respective circumstances;

The water * and moisture proofing are Ib building trade everyday problems that occur in all areas of the construction industry because of the changing ways of working, Changes in the architecture, as well as the increasing costs for materials and labor sunehaend »Ehr Attention to be paid nut. The requirements for waterproofing are generally referred to on protection against larger accumulations of free or running water or water under pressure, for which the following examples are given:

Above-ground parts within the building or in an integral connection with them, for example covers For chip grooves, parts protruding through the wall Above pensters and tares, soaps under the screed in shower rooms, Toilets and kitchens as well as sohuts for canopies above entrances and for stairs.

components above ground or standing on the ground,. which are assigned to the buildings or are located close to them, see B. Terraces, enclosures, access roads, Greenhouses, swimming pools, moats, sidewalks as well as above-ground parking spaces.

109830/1325

Underground installations such as Kellerbötfan and winds, carages below the level of the steam, building history, subterranean engine rooms, subterranean heights Pipes and tunnels for people or machines.

Further examples include storage containers, traffic tunnels, bridges and car parking facilities.

Moisture seals are similar to water seals, as the only fundamental difference is the amount of water to be expected. Moisture withdrawals are necessary when a certain amount of external moisture is to be expected, but there is only a slight probability of edible water pressure and there is no need to prevent water from penetrating from the inside or from above.

The main uses for moisture proofing are in the area of the Untereetrichschutses considerably above dea water table or under plate covers on the αrund, if the possibility of flooding not to be factored in.

This is a relatively difficult job, which is dirty and therefore uncomfortable is and, moreover, more dangerous with development Vapors as well as from Hitse and is associated with considerable fire hazard. The rising labor costs hit this process particularly hard and construction workers are increasingly averse to that Process at all durehsuftthresi · That is called application of asphalt is also disadvantageous because the hot bitumen often cools and solidifies before the roofing felt or the mat can be applied. If a web is applied imprecisely, this often cannot be done correct more because the bitumen has cooled down 1st · Experience has risen, since * only in the case of "adiger" and More accurate monitoring errors can be avoided and even then it is quite difficult to actually find one do a good job. For example, it is important that the hot, liquid asphalt is smooth and is distributed in a uniform thickness, otherwise Can form channels or cavities in which water can fly on or collect, whereby a «

INSPECTED

The material according to the invention consists of a preformed one sheet or sheet material with a sheet-shaped or web-shaped carrier and with a self-adhesive (pressure-sensitive) adhesive as a waterproof and waterproof membrane on a surface of the Carrier, the membrane protruding beyond at least one edge of the carrier «,

The material thus contains a flexible carrier sheet or carrier film made of natural rubber and / or synthetic organic polymers, see B. Polyethylene, that should be stretched for most purposes, and was in the fora of a wide strip. With a surface of the sheet or sheet material is one Waterproof and waterproof membrane extending over the same area and adhering thereto, preferably made of a bituminous rubber compound. the The membrane is soft and pliable. It is noticeably thicker than the carrier material and has the ability to reunite and self-seal and cold flow when pressure is applied to places where the mass is not enclosed by the carrier web "

The membrane can protrude either over one or both longitudinal or transverse edges of the carrier material. One special effective sealing is obtained when the membrane protrudes over the support at both edges.

Until the material is used, the

reverse side of the membrane, preferably with a protective coating or web (e.g. a silicone-treated paper), which can be easily removed without damage «

let the membrane pull away from it. If the material is in the form of a roll, then it is Protective layer is particularly advantageous because it enables the material to be rolled up easily; about that In addition, the direction of the movement can be determined via the Easily control the substrate to be covered.

The accompanying drawings are intended to explain the invention,

The material can have a width of 61 to 122 cm, preferably by about 92 cm and should be as long as in terms of transport, handling and size of the flax to be sealed.

The carrier material should have good water vapor and water impermeability own; it is preferably a polymer in film form. Polyethylene film from 0.013 to 0.051 cm, preferably 0.025 cm thick well suited because it has the functional, feetigkeits- and Flexibility properties combined, which are necessary for the desired results o

The preferred biturnen / rubber mass is made of art ' or synthetic rubber (raw rubber or from waste) obtained, which are mixed with bitumen to form a smooth mixture. The ratio of bitumen to rubber is favorably at least 75:25.

The protective layer preferably consists of a silicone-treated one Paper that can be easily peeled off the membrane. The protective layer extends in width at least over the entire width of the membrane is preferred but a little bigger.

The wide web 9 overlaps the first by a noticeable amount. A direct contact between the membranes of the sealing taps 7 and 9 is achieved at the overlapping at least 10 because the membrane 8 protrudes laterally beyond the carrier of the web 7. The channel is shown in Fig. 1 in one; In the case of the forest version, the membrane protrudes beyond the support on one side only, while the membrane on the other edge

Concrete, intended “that can remain in its raw state”, like it is out of the wooden cladding, but not smoothed. A top layer of, for example, concrete "asphalt" or a "mortar bed, in which bricks, tiles or stones are laid, coats the underlying layer. The material according to the invention is introduced into the two layers. The material is particularly suitable for such constructions because the weight of the top layer protects the water-repellent layer against damage. It exerts a pressure on the web and the membrane and establishes intimate contact between the membrane and the substrate as well as the overlapping webs. The pressure causes re-consolidation and self-sealing, as well as sealing the bottom of any cavities. In such Schiitsplatte constructions a floating screed is often required in addition to a waterproofing, ie the absence of a binding ■ wipe the two layers for a relative movement ■ wipe them. By using the present. Material, the carrier material prevents a bond between the soles without affecting the membrane, which at the same time protects the membrane against damage and wear.

In another application, the material is placed under flats which are laid out on the ground. In this case it is advantageous not to remove the protective layer from the membrane bu either. As shown in Fig. 3, the material is laid out in the form of a roll at one end 14 of the strip covering the su. A small piece of the protective layer 15 is sucked off and the membrane thus exposed is connected to the substrate at the starting point 1 * »It. Then the Ä

Schuteechicht 15 as evenly as possible in the direction of application sucked off * The web is rolled up while the protective layer is peeled off, approximately half the circumference of the roll consists of the membrane 16, which has been freed from the visor, which is a sewing adjustment the role in the direction of interpretation allows. Such control of the role can be achieved by pulling on the rubble layer 15 in the direction IT or by sliding the Roll 16 can be reached on one side.

The invention therefore also relates to a method sur Making a waterproofing on a surface, which is characterized by being on the surface the exposed area of the membrane of an inventive Material applies, with the exposed area

is the side facing away from the wearer. Preferably the method is carried out in such a way that one withdraws a small part of the protective layer, doing a small part of the membrane exposed, whereupon the roller is laid out in a suitable place for rolling along a desired path, the exposed part of the membrane is connected to the substrate and the protective layer is peeled off in the direction of the EU-covering strip, as a result of which the protective material is peeled off the roll and the membrane is exposed; while in the same tent the material rolls up and sticks to the substrate.

As already stated above, a particularly effective one Sealing is achieved when the membrane protrudes beyond the carrier on both. This is due to the fact that the Glue the overlapping edge of the trfigeraiaterinla Glued along the edges of the LSngak and on the underside forms a second seal as the adhesive fries Adhesive comes into contact.

The following are intended to explain the invention Examples serve.
