Geomembranes “Slavros” textured geomembrane

Description

Description The rolled polymer insulating material of the “Slavros” geomembrane is intended for carrying out waterproofing works of various degrees of complexity, protection against corrosion and waterproofing of concrete structures, creation of antifiltration screens.

Textured - designed for use on elevated slopes, as its structured surface improves adhesion of the material to the base, in addition, can be used in regions of seismic activity.

For the manufacture of geomembranes use lowpressure polyethylene or high-pressure polyethylene.

Main applications of geomembrane:

•      waterproofing of layers of the road pavement, lower layers of the roads and railways;

•       storage of industrial and domestic waste (landfills);

•       storage tanks of industrial and agricultural enterprises;

•       anti-filtration protection of storage tanks for petroleum products, automotive gas stations;

•       drinking water reservoirs, irrigation ponds and canals, rainwater collection reservoirs, fire reservoirs;

•       impervious screens;

•       corrosion protection, waterproofing and gas insulation of concrete structures;

•       industrial sludge collectors;

•       storage areas for hazardous substances;

•       soil pollution insulators;

•       dams;

•       lagoons of manure reservoirs;

•       storage of dry products;

•       architectural and landscape ponds;

•       waterproofing inversion roofs;

•       tunnels.

The main advantages of using the Slavros geomembrane:

  • ease of transportation and storage of materials;
  • absolute water tightness;
  • possibility of the vertical anti-filtration barrier;
  • high resistance to mechanical stress;
  • chemical resistance to a wide range of pollutants;
  • high speed of welding; service life more than 80 years;
  • material is absolutely nontoxic, is not dangerous to human health, animals, fish and does not change its properties during the entire service life.
