Our 500-micron Damp Proof Membrane is the ultimate heavy-duty solution for superior moisture protection under concrete slabs. Designed for demanding applications, it provides a high-strength barrier against water and vapour. Made from 100% recycled polyethylene, this BBA-certified membrane ensures reliability and environmental responsibility. Available in black and supplied in multi-fold or centre-fold options, it offers versatility and ease of installation. Ideal for projects requiring maximum durability, it guarantees long-lasting protection for even the most challenging environments.
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.
