Product Description
This 250 micron BBA-certified black polyethylene damp-proof membrane (DPM) provides reliable protection against rising damp in ground-floor constructions. Compliant with BS 8102 and BBA approved, it is suitable for use beneath concrete slabs, screeds and insulation in both new-build and refurbishment projects. Supplied in a 4 m × 25 m roll (100 m²).
Key Benefits
Application
Lay the membrane over the prepared sub-base or blinding layer with a minimum 300 mm overlap at all joints. Seal overlaps with DPM jointing tape. Turn up at perimeters to lap with the wall DPC. Take care to avoid puncturing — protect with a sand blinding layer if laid directly on hardcore. Can also be used as a slip membrane over insulation before screeding with a 150 mm overlap.
Coverage
Each roll covers 100 m² (4 m × 25 m). Allow approximately 10–15% extra for overlaps and wastage depending on floor plan complexity.
