is a three-dimensional composite product, consisting of a drainage core and firmly attached filter nonwoven geotextiles for drainage applications. Secudrain® is multifunctional Secudrain® is used extensively to drain water or gas in various applications. In landfill engineering, Secudrain® serves three functions at once (filtration, protection and drainage) when installed directly above a geomembrane. The ability of Secudrain® to passively relieve water pressure makes it ideal for drainage over buried structures and for road-edge strip-drain applications. The filter geotextiles and the drainage core can be efficiently dimensioned to meet the required drainage capacity. Secudrain® is also used success fully as a drainage layer in the construction of buildings, tunnels and roofs. Advantages of Secudrain® filtration, protection and drainage in one product excellent in-plane flow properties long-term hydraulic performance replaces natural drainage aggregate very high creep resistance resistance to chemical and biological degradation perfectly suited for steep slope application due to very good shear properties robust against on-site conditions quick and cost-effective installation highest quality control standards ISO 9001 certified CE marked

Secudrain® is safe Secudrain® is properly dimensioned durable and robust; it handles mechanical loads with ease. It is resistant to all naturally occurring chemical and biological factors in the soil. The needle-punched nonwovens long-term filter efficiency allows for safe design of passive drainage and thus ensures the system’s longevity. The use of needle-punched non wovens leads to a high interfacial friction angle, especially important on steep slopes. The regular bonding between the geotextile and drainage core ensures transmission of shearing forces through the Secudrain® system. Secudrain®...
