Drainage membrane

PM DRAIN-TEC-ECOnopp® is an effective protection and drainage system and the universal solution for both horizontal and vertical surface drainage on all pressure-resistant surfaces. PM DRAIN-TEC-ECOnopp® consists of a dimpled membrane and a sturdy geotex¬tile. The smooth back side allows for a uniform and extensive load distribution on the sealing. This double-layer system protects the wa¬terproofing below it from mechanical damage and damaging thermal stresses. PM DRAIN-TEC-ECOnopp® has a compressive strength of 400 kN/m². The drainage membrane is available in many different length and width variations. The excellent water draining capacity is multiple times higher than required by drainage standard DIN 4095.

PM DRAIN-TEC-ECOnopp® protects roofs of underground car parks and patio against waterlogging. 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. The optimal high-performance geotex¬tile boasts very high initial strength and is subject to only minimum deformation under increasing working load.

ECOnoppOur sustainable, environmentally friendly and resource-saving product line. The use of regranulates relieves the burden on the environment, reduces energy consumption compared to new plastics and reduces CO2 emissions. This closes the recycling cycle - without even making any compromises on quality or economic efficiency.
