WASTE DISPOSAL WORKS

The nonwoven geotextiles GEO are largely used in waste disposal works and in the reclamation of polluted land areas. An efficacious containment of leachate and polluted liquids by means of geomembrane liners entails that these waterproofing systems must be adequately protected against the risk of mechanical damage. In fact, the geomembranes in contact with rough surfaces or draining gravel, usually subjected to high contact pressure, can be easily punctured without the protection action of a high efficiency nonwoven geotextile.

In the capping operation of landfills, the covering fill material must be separated from the gravel layer for the drainage of rain water. In this way the GEO nonwoven geotextile are installed between the covering material and the gravel layer, performing both functions of separation and filtration
.
