Yes, the Visqueen Zedex CPT is suitable for damp proof course and cavity tray applications in residential, commercial, and industrial building projects.
Ensure a minimum overlap of 150mm between pieces. All joints and laps must be securely sealed using Visqueen jointing tape or compatible jointing compounds to maintain a continuous barrier.

The Visqueen Zedex CPT High Performance Damp Proof Course is supplied in rolls measuring 100mm wide by 20 meters long.
No, the product contains no hazardous pitch or PVC plasticisers, making it safe and clean to handle.
The co-polymer thermoplastic (CPT) construction is designed to protect against the ingress of damp for the lifetime of the building.
Ensure the material has been stored correctly and is not exposed to extreme cold. Allow it to acclimatise to ambient site temperatures before installation for optimal flexibility.
Ensure the substrate is clean, dry, and free from dust or loose debris. Apply mortar cleanly and ensure consistent pressure during installation to achieve good adhesion.
Inspect for any visible tears, punctures, or improperly sealed joints. Repair any damage or seal any gaps using the recommended Visqueen jointing tape or compatible sealing compounds.
Verify that all laps, joints, and penetrations have been meticulously sealed according to manufacturer guidelines. Any unsealed gaps will negate the gas-resistant properties.
Setup: The Visqueen Zedex CPT Damp Proof Course is supplied in rolls for easy deployment. Unroll the material and cut to the required length using a sharp knife. Install in accordance with BS 5603 and BS 743 recommendations. Ensure overlaps of at least 150mm are maintained when joining lengths and at junctions. All joints, laps, and penetrations must be securely sealed using Visqueen jointing tape or compatible jointing compounds to create a continuous barrier.
Compatibility: This product is designed for use in damp proof course and cavity tray applications in residential, commercial, and industrial construction. It is compatible with common building materials including concrete, brickwork, and mortar. It contains no hazardous pitch or PVC plasticisers, making it safe to handle and compatible with a range of construction environments.
Care: As a permanent building element, the Zedex CPT requires no ongoing maintenance. However, during installation, care should be taken to avoid damage from sharp objects or excessive stress. Store rolls flat and protected from extreme weather and UV light before installation.
