PM DRAIN-TEC Surface drainage
PM DRAIN-TEC 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 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, green flat roofs and the outer walls of basements 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.
For inverted roofs: also available as perforated variant.
PM DRAIN-TEC is also a quiet whispering sheet underneath the drainage membranes, because the tested impact sound reduction, in accordance with DIN EN ISO 10140, is up to ΔLw = 27 dB for non-insulated flat roof structures.
As a sustainable drainage sheet variant of PMI-Plast, PM DRAIN-TEC-ECOnopp® has been developed has the same characteristics and properties as PM DRAIN-TEC, but differs in its production. It is produced proportionally from recycled plastics, so-called regranulates ("post-industrial/post-consumer granulate"). In this way, you as a user make an effective contribution to the topic of "climate protection" without having to forego consistent quality and specific product properties.
