Secudrain is a three-dimensional composite product, consisting of a drainage core and firmly attached filter nonwoven geotextiles for drainage applications. Secudrain® is multifunctional and it 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®
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® IS ECONOMICAL
Since the filter, drainage, and protection layer comprise one unit, Secudrain® can be installed rapidly. The use of Secudrain® in earth construction requires less excava tion of in-situ material and, in the case of a landfill liner, the containment volume is increased. Using Secudrain® saves time and natural resources since 10,000 m² of the Secudrain® system can replace the extraction, transport, and installation of approximately 3,000 m³ of granular drainage material. Secudrain® keeps your costs lower than conventional methods.
SECUDRAIN® IS SIMPLE
One or two people can carry and unroll the lightweight rolls of Secudrain® without problem and it can be installed in most weather conditions. Complicated connections are easy with Secudrain® and it readily fits to the contours of the job site.
CONCLUSION
Secudrain® excels by its versatility. The installation is simple and straightforward. Secudrain® is extremely resistant to environmental factors and its use saves natural resources.
