GXP® DREN 40

High drainage capacity

The new membrane GXP® Dren 40 is a retention and drainage module (HDPE) with high water accumulation and load capacity. For applications in intensive green roof systems. The innovative shape and properly selected mixture of hardened polyethylene HDPE ensure extraordinary retention parameters within its class. It is characterized by a very high compression strength, approx. 400 kN/m² (approx. 850 kN/m² after filling with aggregate) as well as extraordinary water accumulation, approx. 15 liters per square meter.

Advantages

  • Ensures very high water accumulation for plants (intensive vegetation)
  • Very high compression strength and breakdown strength
  • Increases thermal insulation
  • Limits heat accumulation
  • Optimal dehydration capacity
