3D Geomat ( EM2------EM5) for slope protection HDPE mesh
Introduction:
Geonet is made of high-density polyethylene (HDPE) and the ultravioresistant agent
Features:
1.Aging resistance
2.Erosion resistance
3.Good Flexibility
Application:
1. Using the geonet on the roadbed of the roadway and railway can distribute the load effectively, improve the loading capacity and the stability of the roadway, and prolong its service life.
2. Spreading the geonet on the slope of road can prevent landslides, conserve water and soil, beautify the environment.
3. Spreading the geonet in the dyke protection in the reservoir and the river can protect it from the landslide.
4. Using the geonet in the coast engineering can amortize the concussion and the erosion of the surf.
Installation Involves:
. Shaping and compacting the sub soil to the required profile.
.Unrolling the 3D Geo-mat down the slope and fixing it in position with 150---300mm u-pegs.U-Pegs should be spaced between 300mm and 700mm depending on the substrate to ensure that the 3D Geo-mat makes contact with the surface.Overlaps should be pegged at 100mm centres in dry applications and 300mm in wet applications….
.Anchoring the top of the embankment in spade-deep trenches and ,Where necessary,anchoring the edges to prevent the 3D Geo-mat slipping on the slope and uplift…
.Longitudinal edges should be overlapped 50mm and transverse edges overlapped 150mm…
.After seeding the subsurface at a rate of 20-30
