Delta MS high dimple density membranes are made of high density polyethylene. They have a high compressive strength and have more than 1800 dimples per metre squared for efficient pressure distribution and low point loads, even on perimeter insulation.

Typical applications include sub-base coursing under concrete floor slabs, foundation wall protection and as a seepage layer within cavity walls.

Delta MS membranes are non-degradable in soil, non-polluting in drinking water and will provide additional heat insulation.

They have flat overlapping edges the ensure precisely fitting joints and a diagonal dimple configuration that permits straight creases.
