The 8mm studded HDPE profile holds the membrane away from the substrate, creating a drainage cavity that channels groundwater to perimeter drainage and a sump pump, controlling water ingress rather than resisting it. The clear membrane makes it straightforward to locate and fix CM Brick Plugs during installation.\u003c\/p\u003e\n\u003cp\u003eThe membrane requires minimal surface preparation and can be applied to walls, floors and ceilings. Because no drying-out period is needed, internal finishes and dry lining can be installed immediately after the membrane is in place.
