Green areas and flat roofs
Drainage membranes are effective, high-performance protection and drainage systems for underground garage floors, terraces with paving stone or wooden coverings, and for extensively or intensively greened flat roofs. Essentially, an efficient area drainage for green roofs is necessary to protect them from waterlogging, which damages the green roof and encourages moss formation.
For this purpose, two-layer drainage sheets such as PM TERRA-TEC are used. In addition to their drainage function, single-layer drain and storage elements for green roofs offer the advantage that they can serve extensively or intensively green roofs as valuable water storage.
This allows greening to be carried out, which can also go for a long time without watering.
The advantages of green roofs
- Longer roof life
- High retention of rainwater
- Improved sound insulation
- Cooling effect outside and inside in summer
- Warming effect in winter
- Binding of fine dust and pollutants
- Habitat for plants and animals
PM TERRA-TEC
PM TERRA-TEC is a high-grade protection and drainage system as well as the universal solution for vertical surface drainage on all pressure-stable substrates.
PM DRAIN-TEC
PM DRAIN-TEC is a high-quality protection and drainage system as well as the universal solution for horizontal surface drainage for green roofs.
PM P-STANDARD GS
PM P-STANDARD GS is a water-storing perforated dimpled membrane and is the ideal solution for extensive green roofs.
PM P-STANDARD GS-GEOTEX
PM P-STANDARD GS-GEOTEX is a water-storing drainage membrane and is the ideal solution for extensive green roofs.
PM P-20
PM P-20 is a water-storing, perforated special knobbed membrane and is the ideal solution for extensive and intensive green roofs. In the green roof, it takes on the function of a protective and water storage layer.
PM P-20-GEOTEX
PM P-20-GEOTEX is a water-storing drainage membrane with an integrated geotextile and is considered the ideal solution for extensive and intensive green roofs. In the green roof, it takes on the function of a protective, filter, seepage and water-storage layer.
PM P-40
PM P-40 is a water-storing, perforated dimpled sheet in plate form for intensive green roofs. It offers a multiple of drainage and water storage capacity.
PM P-60
PM P-60 is a water-storing, perforated dimpled sheet in plate form for intensive green roofs. It offers an extended drainage and water-storage capacity. In the green roof, it takes on the function of an extremely powerful water-storage layer.
