PM 3SG-GEOTEX
Drainage membrane
The three-layer PM 3SG-GEOTEX protection and drainage system is a high-quality addition to polymer modified bituminous thick coatings (PMBC) for exterior basement walls. Thick coatings act as a permanent waterproofing, filling in cracks and joints, but for backfilling or subsequent soil settling, they can be extremely sensitive to impacts and pressure.
The result: elaborate time-intensive and thus cost-intensive safeguarding work for the backfilling process and the risk of later complaints. PM 3SG-GEOTEX solves multiple problems as a complete, multi-layer protection and drainage system for below-ground structures with PMBC or other waterproofings.
PM 3SG-GEOTEX consists of a dimpled membrane, a rugged geotextile and a sliding foil on the back side. The sliding film distributes the effective earth pressure and acts as a sliding surface in case of any settling of the filling soil. The protective effect meets the requirements of DIN 18533. The good water draining capacity of PM 3SG-GEOTEX is multiple times higher than required by drainage standard DIN 4095.
PM 3SG-GEOTEX has a compressive strength of 200 kN/m². The drainage sheet is available in many different length and width variations.
