PM8 Cavity Drain Membrane

PM8 is a dimpled membrane designed for Type C waterproofing below ground. As a cavity drain membrane, PM8 can be used in basements and cellars to effectively control water ingress. The 8mm dimples form a cavity, allowing water to travel to a drainage channel and be safely removed from the structure.

Manufactured from virgin high density polyethylene (HDPE), these dimpled sheet membranes are easy to install and long-lasting. This provides homeowners with peace of mind.  

Uses of PM8 membrane

PM8 dimpled membranes can be used on internal walls and floors of newly constructed or existing basements, cellars and retaining structures.

Installing a PM8 dimpled membrane

For full installation guidelines consult the manufacturer’s instructions. The PM8 dimpled membrane has an 80mm stud-free overlap, making it easier to join the membranes.
