Landfill capping layers often consist of a mineral sealing layer which prevents surface water from being introduced into the waste material.To safely drain off excessive rainwater to a suitable discharge point, a drainage composite such as WD600/4 can be used as a cost effective alternative to granular materials.

Where a geomembrane liner is used, WD 600/4 provides drainage along with protection against damage to the geomembrane.

Conventional methods for landfill drainage and venting may take a great thickness of aggregate, carefully placed and compacted. Unravelling a roll of drainage composite material, weighting down in place, and back filling over can be far more practicable and cost effective. The reduced thickness of a drainage composite maximises the volume available for waste material within the landfill.
