The Visqueen Damp Proof Course - 300mm x 20mtr is designed for construction professionals seeking robust moisture and gas barrier protection. Its key benefit is providing certified protection against damp, radon, and CO2 ingress for the lifetime of the building. A potential caveat is its specific application in damp proof course and cavity tray installations, requiring proper integration with building structures. This flexible co-polymer thermoplastic (CPT) DPC system offers superior strength, tear resistance, and excellent mortar adhesion.

Verify that the DPC was installed at the correct level and that there are no breaches in the membrane. Ensure all laps and junctions are properly sealed. Check for alternative moisture ingress routes.
Confirm that the DPC was installed with all necessary laps sealed and that there are no gaps or penetrations. Ensure the correct type of membrane (gas-resistant) was specified and installed. Consult with a specialist if necessary.
Small tears or punctures can often be repaired using compatible self-adhesive tape or patches designed for DPC membranes. For significant damage, the affected section may need to be replaced.
Ensure the substrate is clean and dry before applying mortar. Use the appropriate mortar mix as specified by building regulations. The CPT material itself is designed for excellent adhesion, so issues may relate to application conditions.
Setup:
The Visqueen Zedex CPT Damp Proof Course is designed for installation within masonry construction. It should be laid on a firm, level base, ensuring it is fully supported. For damp proof course applications, it is typically incorporated into the mortar course at or near ground level. For cavity tray applications, it should be installed within the wall cavity, ensuring a continuous run that directs water outwards through weep holes.
Compatibility:
This product is compatible with standard building materials including brick, blockwork, and mortar. Its excellent mortar adhesion ensures a strong bond. Ensure that all laps are adequately sealed or overlapped according to best practice and project specifications to maintain the integrity of the barrier. It is designed to work seamlessly within conventional wall construction methods.
Care:
The Visqueen Zedex CPT Damp Proof Course is a passive material and requires no ongoing maintenance once correctly installed. Its durable CPT construction is designed to last the lifetime of the building. During construction, care should be taken to avoid puncturing or damaging the material. If damage occurs, it should be repaired according to manufacturer guidelines or best practices for barrier membranes.
