DLT DREN 20 is a nodular drainage sheet (nodule height 20mm) made of High Density Polyethylene (HDPE) for use as a drainage layer and waterproofing protection in tunnels.

DLT DREN 20 has a resistance of 150 kN/m2.

 

FEATURES AND BENEFITS
  • Prevents the formation of hydrostatic pressure.
  • Constant and high drainage.
  • High compressive strength and stability.
  • Great long-term resistance.
  • Promotes proper ventilation.
  • Great protection of the waterproof coat.
  • Respectful of the environment, it does not pollute.
  • Quick and easy installation.
  • Resistant to chemical agents.
  • It is not attacked by humus acids.
  • It doesn’t rot.
  • Prevents root penetration.
  • Allows higher drainage for areas with a large amount of water.
APPLICATIONS
CONSTRUCTION
  • Insulation: DLT DREN 20 acts as an insulator in tunnels and other underground structures exposed to a strong flow of water.
  • Concrete slabs: the high-density polyethylene sheet (HDPE) is applied to slabs with a high load-bearing capacity.
  • Runways: DLT DREN 20 is used to favor runway conditions.
  • Raised floors: The nodular sheet is also used for raised floors.
