Waterproof Exterior Protection

Structures that are earth retaining can be damaged by moisture penetration from the outside or by the water under hydrostatic pressure. DELTA Membranes are available as geocomposites to deal with such problems. They act as a waterproof drainage layer, and quickly remove the water to suitable drainage around the structure. They prevent the build up of hydrostatic pressure on the structure and filter the water via an internal polypropylene filter layer. This prevents the fine ground particles from blocking the drainage facility and avoids destabilising the soil.
