Product Information

Full details

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.

Extended Product Information

FAQs

What does BBA certified mean?

BBA certification (British Board of Agrément) means the product has undergone rigorous testing and inspection to demonstrate its fitness for purpose and compliance with relevant building standards and regulations.

Can this DPC be used in any type of building?

Yes, it is suitable for demanding construction applications, including new builds and renovations, where certified moisture and gas barrier protection is required.

How flexible is the Visqueen Zedex CPT DPC?

It is designed with a flexible co-polymer thermoplastic (CPT) construction, allowing it to adapt to various installation scenarios and contours within the building structure.

What is the expected lifespan of this damp proof course?

The product is manufactured from co-polymer thermoplastic (CPT) to protect against the ingress of damp for the lifetime of the building.

Is this product safe to handle?

Yes, it contains no hazardous pitch or PVC plasticisers, making it safe and clean to handle during installation.

What gases does this DPC protect against?

It provides protection against the ingress of gases such as radon and Carbon Dioxide (CO2).

What are the dimensions of the roll?

The Visqueen Zedex CPT High Performance Damp Proof Course is supplied in 300mm x 20mtr rolls.

Troubleshooting

Inadequate damp proofing after installation

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.

Gas ingress detected despite installation

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.

Material appears damaged during installation

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.

Poor adhesion to mortar

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.

Pros and Cons

Certified performance (BBA) for reliability and compliance.
Effective barrier against moisture, radon, and CO2.
Flexible material simplifies installation.
Durable and designed for the lifetime of a building.
High strength and tear resistance contribute to longevity.
Safe to handle with no hazardous materials.

Cons

Primarily designed for specific DPC and cavity tray applications.
Requires skilled installation to ensure a complete barrier.
Performance relies on correct integration within the building structure.
Not suitable for applications outside of damp proofing or gas barriers.
Specific dimensions (300mm x 20mtr) may require planning for larger projects.

Setup, Compatibility & Care

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.
