Extended Product Information

FAQs

Can this membrane be used under underfloor heating?

Yes, it is suitable for use under most underfloor heating systems, but ensure the insulation layer is placed between the membrane and the heating elements if required by the system manufacturer.

Is this product suitable for external walls?

No, this membrane is designed specifically for floor damp-proofing applications and is not a substitute for a vertical damp proof course.

How do I join two sheets together?

Overlap the sheets by a minimum of 150mm and use high-quality damp-proof membrane sealing tape to create a continuous, moisture-tight joint.

Is the material resistant to heavy foot traffic?

The 300mu thickness is designed to withstand normal site traffic during construction, but it should be protected from sharp tools and heavy, pointed machinery.

Does the 90% recycled content affect the durability?

No, the manufacturing process ensures that the recycled materials meet the same performance criteria and PIFA standards as virgin plastics.

Can I use this for a garden pond liner?

This product is engineered for building construction and damp-proofing. It is not recommended for use as a pond liner due to different material requirements for long-term water retention and UV exposure.

Troubleshooting

Difficulty flattening the membrane

Unfold the membrane in a warm area before installation to allow the material to relax, making it easier to lay flat.

Tearing during installation

Ensure the underlying surface is free of protruding nails, rubble, or jagged stones; clear the site thoroughly before laying the sheet.

Moisture seeping through seams

Verify that all overlaps meet the minimum 150mm requirement and are securely sealed using specialized DPM jointing tape.

Pros and Cons

Pros

High-grade puncture resistance for site durability
Easy-to-handle dimensions for smaller projects
Environmentally conscious material composition
Reliable barrier against damp and moisture
Industry-standard performance verification

Cons

Requires professional sealing tape for continuous joints
One fixed sheet size may necessitate multiple packs for large areas
Not intended for use as a vertical damp proof course

Setup, Compatibility & Care

Before installation, ensure the sub-base is clear of sharp debris that could compromise the membrane's integrity. To achieve a complete seal, use a compatible DPM-rated adhesive or jointing tape at all overlaps and junctions with wall edges. The membrane is compatible with most standard concrete and sand-cement screed systems. Store the pack in a cool, dry place away from direct sunlight and sharp objects until the moment of installation. If the membrane is punctured during the construction process, repair the hole immediately with a patch of the same material, ensuring the patch is properly taped on all sides to maintain the moisture seal.
