Damp Proof Membrane 250

Damp Proof Membrane

250 Microns

Our much praised record producing DPM’s and a continuous investment programme has produced a comprehensive range of high quality damp proof membranes. Produced in blue or black and manufactured from high quality recycled polyethylene for use in solid concrete ground floors to protect buildings against water from the ground providing an effective barrier against liquid or water vapour for the lifetime of the concrete slab in which they are installed. Our externally audited quality system ensures attention to detail from start to finish of our manufacturing process. This enables us to offer both BBA and PIFA standards and ultimate confidence in the integrity of your products. We manufacture to both B.B.A & P.I.F.A standard.

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.

Installation

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.

Production Proccess

Our process starts with taking recycled plastic and feeding it into an industrial shredding machine. This step breaks down the plastic into smaller, manageable pieces, preparing it for further refinement.

Once the recycled plastic is shredded, it’s heated and melted down into a molten form. This crucial step prepares the material for molding, ensuring consistency and quality in our products.

The melted material is blown, stretched, and carefully pressed into shape before being cooled down. This process solidifies the structure, ensuring strength and durability in the final product.

Each product undergoes rigorous quality checks to meet our high standards. Once approved, the materials are carefully packaged, ready for distribution to ensure safe delivery to our clients.
