8mm Membrane - Clear - Biokil Crown
Biokil Crown 8mm Membrane – Clear
High-Capacity Cavity Drainage Membrane for Below-Ground Waterproofing
Biokil Crown 8mm Membrane – Clear is a robust, high-capacity cavity drainage membrane designed for internal waterproofing applications in basements, retaining walls, and other below-ground structures. Manufactured from clear high-density polyethylene (HDPE), the membrane features 8mm studs that create an air gap between the substrate and internal finishes, allowing water to drain freely into a perimeter drainage system or sump. The clear construction allows for visual inspection of the substrate during installation, making it ideal for damp-proofing and structural waterproofing.
Key Features & Benefits
- 8mm Stud Height: Provides excellent drainage capacity for high-moisture or below-ground environments.
- Clear HDPE Construction: Enables visibility of substrate for inspection and detailing during installation.
- Moisture Isolation: Prevents moisture and salt transfer from masonry to internal finishes.
- Compatible with Systems: Works with sump pumps, perimeter channels, and sealing accessories for full cavity drain systems.
- Durable & Chemically Resistant: Resistant to alkalis, acids, bacteria, and fungi – ideal for long-term installations.
Product Details
- Material: High-Density Polyethylene (HDPE)
- Stud Height: 8mm
- Thickness: Approx. 0.6–0.7mm
- Colour: Clear
- Roll Size: Typically 2m x 20m (40m² per roll)
- Fixing Centres: 250mm with Biokil Crown Brick Plugs or Newton MultiPlugs
- SKU: BC8CLR
Application Instructions
- Prepare Substrate: Ensure wall or floor surface is stable and free from sharp projections or loose materials.
- Cut & Fit: Trim the membrane to size using a utility knife or shears, ensuring full coverage of the surface.
- Fixing: Use appropriate fixing plugs with seals at 250mm centres. Seal around plug heads if required using mastic.
- Sealing & Finishing: Overlap sheets by at least one stud column and seal with jointing tape or overtape. Connect to drainage or sump system as specified.
Limitations
- Not suitable as a standalone waterproofing system without drainage provision.
- Internal finishes should not be applied directly to the membrane without an appropriate air gap or lining system.
Health & Safety
Wear appropriate PPE during handling and installation. Use caution when cutting membrane edges. Refer to the Safety Data Sheet (SDS) for full safety information.
