Effectiveness and Application
Geospan М HDPE is a high-density polyethylene 1.5 mm or 2mm thick geomembrane with a smooth surface. It is designed, per GOST 56586-2015, for the purposes of corrosion protection, providing antifiltering screens and waterproofing of various complexity, including waterproofing of concrete structures.
Geospan M use allows:
- lower construction and service costs through longer service life;
- lower construction cost as compared to conventional material application.
Geospan M application:
- construction of transport facilities under hard geology conditions;
- waterproofing of sites, warehouses, industrial and chemical reservoirs, and landfills.
