PM 2SW-GEOTEX

Drainage membrane

PM 2SW-GEOTEX is an effective protection and drainage system, and the universal solution for horizontal surface drainage on all pressure-resistant substrates.

PM 2SG-GEOTEX consists of a dimpled membrane and a rugged geotextile. The smooth back side ensures an even load distribution across the waterproofing.

This two-layer system protects the waterproofing beneath against mechanical damage and harmful thermal stress. PM 2SG-GEOTEX has a compressive strength of 200 kN/m². The drainage sheet is available in many different length and width variations. The high draining capacity is multiple times higher than required by drainage standard DIN 4095.

PM 2SG-GEOTEX protects roofs of underground car and patios against becoming waterlogged.

The moisture penetrates the geotextile and enters the ducts of the dimpled membrane, where it is securely drained. In the process, the geotextile acts as a filter and prevents the ducts from getting clogged up.
