In general, it is desirable that the carrier for Water is practically impermeable. For many uses purposes, a carrier material is favorable, which according to the Application to a surface in the event of dimensional changes in the Concrete or other material * e.g. due to shrinkage * stretches so that moisture and water drainage

The seal used is retained. For this reason , it is desirable that the combined material of carrier material and membrane at 20 ⁰ Ci has an elongation at break of at least 300 £, among others If, however, elasticity and flexibility are less important than other properties, then you know what materials are used that do not meet the above-mentioned requirements. For example, it is desirable for some application sweets to use! Setallfollen, especially made of copper or aluminum, as ^ rSgermateri & i su *

The preventive carrier materials are foils made of natural rubber or a synthetic organic polyisere such as polyethylene, which is preferred ( e.g. in the form of the product available under the label "polythene"), polypropylene or other polyolefins, a polyamide, a polyester such as "Bo Folyäthylentherephthalat, a Pelyiareth ^ ie F @ lyvtnyl, © hlorid, a mixed polymers of vinyl chloride unu vlny !!

Inorganic © or metallic carrier materials can also be used ο

Particularly when used in road construction, it is desirable ₉ that hot asphalt can be poured directly onto the carrier without the waterproofing suffering as a result. For this swecke, the carrier material should withstand temperatures of at least 150 and a precautionary set of at least 175 ° C for asphalt sights such as sand / asphalt and even higher temperatures for hot asphalt.
