Hydraulic Works

Easy to install and highly resistant, elastomeric bitumen geomembrane Teranap TP provides an industrial solution to waterproofing of all kind of hydraulic works: dams, canals or basins and ponds. Its chemical resistance makes it prefect for drinking water reservoirs and environmental protection hydraulic works.

Water retention installations:

  • Irrigation works: earth canals, concrete canals, aqueducts, reservoirs.
  • Dams, embankments.
  • Drinking water reservoirs.
  • Fire-fighting water tanks, sprinkler basins.
  • Storm water regulation ponds.
  • Leisure lakes, ponds for golf courses, fish breeding ponds.
  • Waste water storage and sewage treatment.
Performance requirements
  • Excellent resistance to ageing when UV exposed: resistance to high differences of temperatures and severe climatic conditions;
  • High resistance to puncturing: the geomembrane can be laid on a substrate which is not specially prepared;
  • Easy anchoring and joining to concrete structures;
  • Reliability and simplicity in application;
  • High level of mechanical properties, especially resistance to puncturing;
  • Elongation and flexibility thanks to the elastomeric bituminous blend;
  • High friction angle thanks to sanded surface.
Teranap TP is a geomembrane manufactured from SBS elastomeric bitumen reinforced with a non-woven polyester geotextile. The underside, covered with a polyester film, is highly resistant to root penetration. The surface is coated with silica sand.
If neccessary, it is possible to strengthen one or several characteristics of Teranap TP, by bonding an anti-puncturing or a drainage geotextile, UV-stabilised (Teranap GTX).
