Protection against bed and bank erosion on trenches and brooks

Erosion protection systems support near-natural trench course development

Permanent and temporary erosion control systems support the development of near-natural watercourses. They act against erosion by fluids such as wind or water, enable groundwater protection and help increase water quality and habitat diversity.

For trenches and brooks, the focus is on creating a suitable and natural surface for flora and fauna that also complies with the environmental principles, e.g., those of the EU Water Framework Directive.

Temporary natural fibre systems

100% biodegradable natural fibre systems with coir fibres are ideal for temporary installation. with coir fibres are ideal for temporary installation. They reduce flow velocity and support diverse brook hydraulics.

Georolls e.g., allow the flow to be specifically adjusted and therefore provide water morphological process areas. The size of the individual semipermeable elements and the modified flow allow flow and cross-sectional forms, current shadows, scouring, fords and embankments to form. The resulting complex dynamic structural diversity drives extremely good ecological conditions in flowing water bodies.

Typical solution

Permanent geotextile systems

For permanent installation, geomat product combinations of 3D Mesh and nonwoven components are suitable. The erosion control mats are modular and consist of a UV-stabilised, biologically, and chemically resistant 3D Mesh.

They reduce the flow energy at the trenches and brooks bottom so that only smaller particles can be transported and provide space for sedimentation. In combination with the nonwoven component, they additionally support particle retention below the product by forming a particle barrier.
