Drainage mat enhances structural stability with efficient water management

Secudrain® drainage mats are engineered geocomposites designed to provide effective water discharge and long-term stability across various construction applications. Each mat comprises a wave-extruded monofilament drainage core thermally bonded to one or more Secutex® nonwoven geotextiles, ensuring high shear resistance and durability. This configuration replaces traditional thick gravel drainage layers, offering a more economical and efficient solution. Secudrain® is ideal for applications such as landfill capping systems, where it drains recultivation soil layers; building structures like bridge abutments and basements, where it prevents hydrostatic pressure build-up; and multi-layered sealing systems, where it facilitates leachate detection. The mats’ high void ratio ensures excellent water discharge capacity, while their robust construction guarantees long-term performance even under significant compressive loads. By simplifying installation and reducing the need for heavy drainage materials, Secudrain® contributes to cost savings and enhanced structural integrity in civil engineering projects.

Secudrain® drainage mats

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.

Typical solutions with Secudrain®

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.
