High-Strength Prefabricated HDPE Dimpled Drainage Mat (0.40″)

RamDrain DD-040HS is a 0.40″ thick high-strength prefabricated HDPE (high-density polyethylene) dimpled mat designed to provide drainage beneath accessible areas that do not need water storage and on vertical building components. It is typically used in areas necessitating a moderate compressive strength material for drainage, specifically for low load pedestrian accessibility for pavers, concrete or asphalt walkways, and patios.

It is typically used in areas necessitating a moderate compressive strength material for drainage, specifically for low load pedestrian accessibility for pavers, concrete or asphalt walkways, and patios. 

 

FEATURES:

  • Is a composite drainage layer consisting of a three-dimensional drainage core and a filter fabric.

  • Includes a filter fabric bonded to the core, preventing intrusion of the overburden into the drainage channels.

  • Retains soil or sand particles as well as freshly placed concrete allowing filtered water to pass through to the drainage core.

  • Is typically used in areas necessitating a moderate compressive strength material for drainage, specifically for low load pedestrian accessibility for pavers, concrete or asphalt walkways, and patios. 

 

USES:

  • Drainage below insulation in inverted assemblies

  • Pedestrian compressive strength grade drainage used below pathways or vegetated areas that do not need water storage
