The 300-micron Damp Proof Membrane offers enhanced durability and protection, making it suitable for medium-duty applications under concrete floors. Made from recycled polyethylene, it provides a robust barrier against ground moisture and vapour. Available in black or blue, this BBA-certified product is supplied in both multi-fold and centre-fold formats, ensuring convenience during installation. Perfect for projects requiring a dependable, mid-thickness membrane, this solution combines superior performance with sustainable production, delivering confidence for long-term moisture protection.
When the sheet cannot be kept dry, form a double-welted fold using at least 300 mm of membrane. Secure the fold in place before adding concrete, e.g., by weighting with bricks.
Ensure the damp-proof membrane is continuous with the surrounding wall’s damp-proof course, using it as a vertical link if necessary.
Cover the membrane with a screed or protective layer promptly. Avoid stretching or displacing the membrane when adding concrete or screed, and allow for bridging prevention at internal angles.
Our Damp Proof Membrane is designed for easy installation, providing robust protection against moisture. Follow our recommended guidelines for optimal results, ensuring long-lasting durability and compliance with industry standards in every project.
