Installation procedures

 

· Prepare the surface by removing large objects, filling any voids to obtain a smooth surface.

· Fix the geomat at the crest of the slope by means of “U” shaped pins (supplied separately).  In some cases an anchor trench may be required for extra stability.  Anchor trench dimensions are typically 400mm wide by 300mm deep.

· Unroll the geomat downward and cut to desired length.  Adjacent strips may be butt joined or overlapped by approximately 100mm.

· Fix the geomat with “U” shaped pins at approximately 1.0m centres and at the joints.

· Place the bottom end of each strip in a similar anchor trench (if required) and bury with soil.

· Brush with topsoil until geomat if filled.

· Spread with grass seed at a rate of 50gm/sqm.      

Geomat Erosion Control is a three-dimensional mat made from extruded and bi-oriented polyethylene grids.  The underside of the mat is made flat to provide even contact with the prepared soil surface.  The upper surface is made cuspated to provide excellent soil retention.  The three dimensional structure retains a layer of top soil and anchors the growing grass roots thus providing a stable surface highly resistant the forces of rain drops and run off.
