  • Excellent capacity for drainage of groundwater. Rot-proof and does not contaminate drinking water.

  • Good tensile strength, compression and chemical agents.

  • Evenly distributes soil pressure.

  • Improves the thermal finish due to the air gap created between underground walls and the drainage sheet, allowing them to be ventilated and guaranteeing effective drainage.

  • Protection for waterproofing thanks to its high resistance to breakage, compression and traction.

  • Especially recommended to withstand the pressures of land, impacts and edges of gravel and stones.

  • Retains moisture from the ground before it reaches underground walls.

  • Ensures efficient drainage of any infiltrations through the nodules chamber.

  • Easy to apply, simply unroll the sheet and attach mechanically.

When applied on bituminous membranes with the cells facing up, it acts as an excellent mechanical protection and anti-root barrier for waterproofing. The cells can support a layer of gravel that will drain under the final cover.
