Non-woven geotextile SECUDRAIN®

polypropylenefor filtrationfor drainage

The drainage mat Secudrain® is a geocomposite of a wave-extruded monofilament drainage core and at least one Secutex® nonwoven geotextile as separation / filtration layer. All components are made of polypropylene and are firmly bonded with each other. Drainage of recultivation/cover soil layers on sealing systems Gas drainage under sealing systems or buildings Leachate detection in multi-layered sealing systems Seepage water drainage at building structures such as bridge abutments, cellars etc. The long-term behaviour of Secudrain® WD has been extensively investigated in both, laboratory and field tests. The wave structure of the drainage core ensures a high hydraulic capacity in the long term. Conventional drainage layers consist of several decimeters thick gravel or similar coarse material. Secudrain® replaces mineral material equivalently at significantly reduced work assignment and machinery application due to easier transportation and installation. Secudrain® geocomposites achieve high inner shear strength due to thermal fusion of the geotextile components to the drainage core. This shear resistant bond also simplifies installation of geocomposite panels.
