20mm Stud Membrane - Black - Biokil Crown - High-Capacity Cavity Drainage Membrane
Biokil Crown 20mm Stud Membrane – Black
High-Capacity Cavity Drainage Membrane for Basement Floors and Ground-Bearing Slabs
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.
Key Features & Benefits
- 20mm Stud Height: Provides superior drainage capacity for high water table or flood-risk environments.
- Ideal for Type C Systems: Designed for use in cavity drainage systems in accordance with BS 8102:2022.
- Durable HDPE Construction: Tough, impact-resistant membrane for long-term below-ground installation.
- Floor Protection: Isolates finishes from damp or contaminated concrete slabs and helps manage hydrostatic pressure.
- Compatible with Drainage Channels: Easily integrates with perimeter drainage systems and sump/pump units.
Product Details
- Material: High-Density Polyethylene (HDPE)
