Product Information
Full details
The Type E Internal Cavitray Insert is a professional-grade DPC solution designed for contractors and property owners looking to address damp issues in existing cavity wall structures. Its primary benefit is the ability to provide robust moisture protection by removing only a single course of bricks, significantly reducing labor and site disruption. A key caveat to keep in mind is that while the system is designed for ease of use, it requires precise mortar application to ensure the interlocking components form a completely watertight seal during installation.

Setup, Compatibility & Care
- Preparation: Identify the affected brick course and remove one layer carefully. Ensure the cavity is clear of debris.
- Adjustment: Measure the existing cavity width and adjust the tray components to match the 50mm-140mm range.
- Installation: Place the tray into the cavity, ensuring the rear upstand is securely positioned against the inner leaf.
- Sealing: Use appropriate mortar to bed the tray. Ensure all interlocking points are properly aligned to prevent gaps.
- Maintenance: Periodically inspect weep holes and exterior masonry to ensure no blockages prevent the drainage of moisture managed by the tray.
