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.

FAQs

Does this tray fit all cavity widths?

It is designed to adjust to cavity widths between 50mm and 140mm.

Can I install this myself?

While designed for efficiency, it is recommended for those with masonry experience to ensure compliance with building regulations.

Is the material waterproof?

Yes, it acts as a permanent DPC barrier against moisture ingress.

How many brick courses need to be removed?

Only one brick course needs to be removed for installation.

What is the function of the Anticapil design?

The Anticapil feature prevents moisture from traveling across the joint between two tray sections.

Troubleshooting

Tray does not sit flush against the inner leaf

Check the cavity for excessive mortar droppings or debris and clear the space before re-inserting.

Difficulty in aligning interlocking sections

Ensure the trays are level and verify that no mortar has hardened inside the interlocking track during placement.

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.
