Rubbertech Roofing R-tech drainage layer is a composite geo-mat made from polypropylene, with a non-woven filter on one or both sides.
The extremely high voids content of R-tech drainage layer ensures a high water flow capacity, especially at low overburden pressures.
Typical applications for the R-tech drainage layer include roof drainage, wall & cellar drainage, landfill surface drainage/sealing and retaining wall drainage.
• Reduced excavation
• High in-plane flow rate
• Massive weight reduction
• Optimum soil retention
• Easy installation
• Chemical resistant
• Biologically resistant
Rubbertech Roofing R-tech drainage layer reduces excavation and therefore construction costs, the high flow rate of the R-tech layer corresponds to a 20-30cm layer of drainage gravel.
One roll of R-tech drainage layer weighs just 24-35 kg, replacing 15-20 tons of gravel, The controlled product quality guarantees constant filtration and drainage performance.
The use of R-tech drainage layer with geo-textile as a filter guarantees optimum soil retention capability and water permeability.
R-tech drainage layer is chemically and biologically resistant and absolutely environmentally friendly.
