Trinter Soil Retention Mat

Trinter is an erosion control net made of strong polyethylene and polypropylene. It offers permanent protection against soil erosion from the moment it is installed and is being used extensively throughout Europe with great success.

Applications

Steep slopes, river banks, ditches, spillways and other exposed areas are often prone to damage caused by erosion of soil by wind or water. Vegetation can help protect against these erosive forces but often the soil is washed away before the vegetation is able to establish a strong root system. Terram Trinter Soil Retention Mat reduces the destructive forces of water and wind and provides a long term root reinforcement system.

Installation

Excavate the slope, fill any voids and make smooth with no ruts or undulations. Secure the Trinter soil retention mat at the top of the slope into an anchor trench and/or fix using steel pins. Unroll Trinter down the slope ensuring that the ‘soil pockets’ run horizontally. At each roll change place the leading edge under the preceding roll with a 100mm overlap. Secure the lap with steel pins. Continue installation along the slope length and overlap adjacent rolls by 100mm. Secure the overlap using steel pins at 1m centres.

Fill the Trinter Mat with topsoil ensuring that there are no gaps between the soil filled Trinter and the slope surface. Hydroseed onto the soil filled mat to encourage vegetation.
