Fatrafol 803/V – Hydro isolation

FATRAFOL 803 is identified first of all for the clamped waterproofing of ground and underground buildings to aggressive, pressure and sucking water and as a waterproofing layer of waterproofing systems to leakage of liquids and leaches into the ground waters. The membrane is suitable for insulation of ground tanks, reservoirs, agricultural buildings, water constructions and dispose of industrial products, which chemical influence respond to the membrane resistance warranted by the producer. The applied membrane fulfils also a function of anti-radon barrier within its
waterproofed function.

  • Waterproofing against ground moisture, pressure water and radon;
  • the material is an unreinforced membrane on a base of plasticized polyvinylchloride (PVC-P);
  • not suitable for the direct contact with drinking water;
  • the membrane can be mutual joined by hot air welding;
  • the membrane has excellent chemical resistance to most inorganic  acids, bases and their salts.
