Secudrain® drainage geocomposites consist 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.
Advantage 1: Excellent long-term behaviour of Secudrain® drainage geocomposites
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.

Advantage 2: Secudrain® is economic and efficient
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.
Advantage 3: Thermally fused components for high shear resistant bond
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.
Secudrain® is used extensively to drain water or gas in various applications. In multi-layered sealing systems, Secudrain® fulfills multiple functions.
Three functions in one product – Filtration, protection and drainage
Secudrain® safely discharges seepage water of the covering soil layer. Additionally, it also filters the soil by means of the firmly attached nonwoven cover geotextile.
Sealing elements such as geomembranes are protected by Secudrain® against coarse particles of the adjacent soils.
Secudrain® drainage mats – Economic and efﬁcient
The 1.90m or 3.80m wide and typically 35m or 70m long Secudrain® rolls are quick and easy to install. The pre-manufactured overlap configuration of Secudrain® provides a simple and quick butt jointing of the geocomposite panels in the longitudinal direction.
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® drainage mats saves time and natural resources since 10,000m² of the Secudrain® system can replace the extraction, transport and installation of approximately 3,000m³ of granular drainage material.
