Secudrain®

Secudrain®

Secudrain® is a three-dimensional drainage system consisting of a drainage core and at least one geosynthetic filter layer. The filter layer protects the drainage core from the ingress of soil particles while allowing the inward movement of gas and water. All layers are regularly bonded together to maintain a high shear strength. Secudrain® solves liquid and gas drainage problems.

Secudrain® is used extensively to solve water and gas drainage problems in landfill and road construction applications.

In landfill engineering, Secudrain® serves three functions at once (filtration, protection, and drainage) when installed directly above a geomembrane. Secudrain®’s ability 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 and intended use. The raw materials of the drainage core and geotextiles can be selected to resist the effects of contaminants in the soil or leachate. Secudrain® is also used successfully as a drainage layer in the construction of buildings, tunnels and roofs.

Secudrain® is durable and robust; it handles mechanical loads with ease. It is resistant to all naturally occurring chemical and biological factors. For resistance to highly aggressive chemicals, Secudrain® can be manufactured with HDPE. 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 nonwovens 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.

Since the filter, drainage, and protection layer comprise one unit, Secudrain® can be installed rapidly. The use of Secudrain® in earth construction requires less excavation 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. 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.

Secudrain® excels by its versatility. The installation is simple and straightforward. Secudrain® is extremely resistant to environmental factors and its use saves natural resources.
