Material for making a waterproof layer on a surface and method of manufacture waterproof insulation

The invention relates to a new one; Isoliergrund and Adhesive in the form of pre-fabricated sheet material. The material according to the invention is particularly suitable for mounting bring to concrete surfaces and will be described in the following mainly on the basis of this use »It is however, it is clear that the description also applies to the application of the sealing material on other surfaces, especially those in civil engineering and civil engineering.

It is already known to use surfaces, especially those made from Concrete, by making a membrane from a bituminous To establish a connection or something similar that is almost impermeable to moisture and water vapor (the term "Bituminous compound" in this specification includes compounds,., which contain asphalt, tar or pitch) ν It is further known that such a connection is an adhesive for a layer of covering material, such as brick or Strips of linoleum, polyvinyl chloride, thermoplastic Material, natural or artificial stones or cork, wooden blocks

or wooden strips. So far such Membranes made by having stalls in place liquid bitumen, tar or pitch or a cold solution. or an emulsion of bitumen, tar or pitch has been applied; » If necessary, the membrane can be replaced by latex aesthetic fibers or other fillers are reinforced «It isfc aßeröem already known for the production of a waterproof membrane To produce layers of polyethylene, synthetic or natural rubber or bituminous roofing felt «

These known methods have considerable disadvantages. Generally, the layer of primer is made in-situ, making it difficult to make a uniform layer and adding significant cost to the labor on site. If the surface also consists of a concrete floor that is exposed to increasing moisture ₃ the adhesive must form a water- and alkaline membrane so that water-based adhesives cannot be used. In practice, this means that a bituminous compound hot applied to the ground πηιβ * which is very undesirable, or that a solvent-based bituminous compound must be used, which is expensive and flammable , at the most icy time possible

If desired, the membrane can be removed • There are a number of layers of waterproof, pressure-sensitive Adhesive (the adhesive can li; the different Each splint can be the same or different).

The materials according to the invention are of two different types su distinguish. The first type is continuous waterproof membrane is glued to one surface and the other surface of the membrane is non-adhesive. The second type is a layer of pressure-sensitive on one surface Adhesive provided. This layer can cover the entire surface

take, so that a continuous waterproof membrane arises, or be provided only on selected parts of the surface.

In the case of the "material of the first type, the substrate consists of a layered carrier - (tB, a layer of organic foliage" such as polyethylene "as will be explained in more detail below) to which the membrane is glued (ie. The carrier and the membrane bltibea when using the material old glued together). They are turned away from the diaphragm.

the membrane can be pulled off this. It is of course clear that for the storage of the material the surface of the membrane facing away from the subsurface has to wear such a protective coating. Therefore, the material according to the invention, which is manufactured in the factory, stored and then brought into place * consists of several layers, namely a protective coating, the membrane and either a layered carrier (in the first type) or a second protective coating ( in the

second kind). The material according to the invention becomes, ™

Usually supplied in the form of rolls.

The material according to the invention is applied with the free surface of the membrane to the surface to be sealed and / or provided with an adhesive layer. In the latter case, the protective coating is removed at some point in order to make the other surface of the membrane ready for the application of the cover material. In order to create a continuous waterproof layer over the entire surface, the material can be laid λ so that the membranes overlap one another.

The width of the new material can be changed within wide limits be, for example between 2.5 and 120 cm and more. this Does not depend on the respective purpose. Generally amounts to the width at least 5 cm, e.g. 15 to 90 cm, with widths from 60 to 90. are preferred if an entire surface is waterproof

A variety of adhesives can be used for the membrane. However, the membrane must adhere to the desired surface without the application of heat or additional binders. D .HER must for the treatment of Betonfläehen which are relatively rough and dusty, a Klebemittelschicfct, are preferably used by 0,0β3 to O ₃ S cm Sterke of at least 0.025 cm. The thicker the adhesive layer, the better the waterproofing effect. In general, a layer 0.063 to Ο, Λ cm thick is sufficient. However, a thickness in the upper part of this range is preferred. Therefore, for material of the first type on the carrier, a single layer of adhesive with a thickness of 0.23 to 0.3 mm is preferred. For material of the second kind, a similar thickness is preferred. This can be achieved, for example, by two layers of adhesive, each 0.1 to 0.18 cm thick, which are arranged on both sides of a reinforcement panel.
