PM DRAIN-TEC is an effective protection and drainage system and the universal solution for horizontal surface drainage on all pressure-resistant surfaces. PM DRAIN-TEC consists of a dimpled membrane and a sturdy geotextile. The smooth back side allows for a uniform and extensive load distribution on the sealing. This double-layer system protects the waterproofing below it from mechanical damage and damaging thermal stresses.
PM DRAIN-TEC 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 protects earth-covered roofs of underground car parks, patios and green flat roofs 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 geotextile boasts very high initial strength and is subject to only minimum deformation under increasing working load.
