The single-ply dimpled membrane is high-performance drainage membrane and represents the ideal solution for the drainage of rising water, seepage water and back­water

Advantages:

• The drainage membrane offers the drainage capacity of conventional dimpled membranes many times over. The 20-160 is used in civil engineering, e. g. as permanent formwork between shoring and concrete structural wall. Accumulated water can then already be drained in the shell construction phase
• The dimple height of 20 mm offers an enormous drainage capacity of approx. 8,54 L/s·m. The pressure resistance of approx. 160 kN/m² ensures a high level of security and corresponds to a compressive strength of 16 t per m²
• In tunnel construction too, the 20-160 membrane offers major advantages. When installed horizontally, it takes up large quantities of mountain water and securely drains it into the drainage line at the base. For flood protection, the 20-160 is laid horizontally between the base slab and the top concrete layer or reinforced screed. This way, any water that accumulates as the groundwater level rises is securely discharged into the drainage line, where it can be pumped out

Installation:

• Roll out the drainage sheets on a level, stable surface, allowing the sheets to overlap lengthwise and crosswise by 20 cm; it is recommended that the rolls be as wide as possible
• The drainage membrane offers protection against rising damp. It also prevents cement paste from flowing downwards
• It is suitable for both new buildings and renovations; the sheeting can also be used in conjunction with various floorings. It is also possible to combine it with sound insulation or different floor heating systems
