Geomembranes “Slavros” сomposite geomembrane

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.

Composite is material with smooth geomembrane and a draining non-woven geotextile coating that protects the geomembrane from damage when used on poorly prepared substrate.


Low-pressure polyethylene or high-pressure polyethylenes are used in the manufacture of these geomembranes.

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.
