Traditional ways of strengthening the slopes and splays by monolithic concrete, concrete slabs or bars do not provide a reliable and long-lasting protection of splays from the damaging effects of natural factors. Soil stabilization constructions with usage of volumetric plastic geogrids can reliably protect the surface of cones from water and wind erosion.
Geotextile — is a synthetic fabric made of polypropylene, waterproof and resistant to chemical influences of the environment. The material is intended to strengthen the soil, separation of the soil layers, and providing filtration of groundwater and wastewater.
