GEOSYNTHETIC DLT DREN 20

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.

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.

The application of 20 mm drainage geosynthetic has a number of advantages:

  • 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

DLT DREN 20 is a geosynthetic allowing more drainage areas and is used for works which are characterized by a high amount of water. It is also a geosynthetic that can be applied in:

  • 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.

FUNCTIONS

DLT DREN 20 is a geosynthetic that performs the functions of:

  • Waterproofing: the nodular drainage sheet performs the waterproofing function in tunnels.
  • Drainage: Performs the function of passing a fluid from one place to another in liquid or gaseous form, performing the function of elimination by evacuation in the thickness of the geosynthetic.
  • Separation: It avoids contact between two materials with different properties and avoids mixing and possible contamination.
  • Protection: DLT DREN 20 protects the waterproof coat.
