Yuzet Damp Proof Membrane - Black

This membrane is primarily used in the UK building industry as a damp proof course (DPC) or damp proof membrane (DPM) to prevent moisture from rising from the ground into buildings.

Yes, it is suitable for most common construction types in the UK, including new builds, extensions, and refurbishment projects, particularly under floors and in walls.

The use of 100% recycled polythene does not compromise its performance as a damp proofing barrier. It meets industry standards for durability and effectiveness.

BBA certification means the product has undergone rigorous independent testing and assessment for quality, safety, and fitness for purpose, giving users confidence in its performance.

While primarily designed for internal damp proofing applications beneath structures, its suitability for external use would depend on the specific application and local building regulations. Consult with a building professional for external use cases.

Store the membrane in a cool, dry place away from direct sunlight and extreme temperatures. Protect it from physical damage.

When installed correctly and protected from damage, damp proof membranes are designed to provide a permanent barrier against moisture throughout the life of the building.

Carefully inspect the area. If a small puncture is found, patch it using BBA-approved repair tape. For larger tears, a new section may need to be overlapped and sealed.

Ensure the surfaces are clean and dry before applying tape or sealant. Use the recommended BBA-approved products and follow their specific application instructions. Press firmly to ensure adhesion.

Verify that the membrane was installed correctly with adequate overlaps and proper sealing. Consider if other moisture sources might be present in the building that are not related to ground damp. Consult a damp proofing specialist if problems persist.
