Biokil Crown 20mm Stud Membrane – Black is a heavy-duty, high-capacity cavity drainage membrane designed for use on basement floors, raft foundations, and ground-bearing slabs where maximum drainage and water movement is required. Manufactured from high-density polyethylene (HDPE), the 20mm stud profile creates a large drainage void beneath floor finishes, directing water to internal drainage systems or sumps as part of a Type C waterproofing solution.
Always wear gloves and protective clothing when cutting or handling. Refer to the product's Safety Data Sheet (SDS) for full health and safety guidance.
