Preformed cavity tray system
Works by reducing on site exposure to the membrane through the use of independent performed and rigid cavity trays installed to the perimeter of the building, in both the cavity wall with our PCT range and installed at the slab edging with our SPT range.

PCT Range – Horizontal cavity wall perimeter trays
Supplied in 2.5 metre lengths and manufactured from heavy duty 2mm polypropylene. They should be installed continuously around the external perimeter of a building to allow the membrane to be laid at a later stage and so prevent damage as building works proceeds.

Corners – PCT and SPT ranges
Available in both SPT and PCT ranges and manufactured from heavy duty 2mm polyethylene. The standard corners are 90° but a wide range of options are available and selection is by cavity size, wall construction and damp proof course or slab rise required.

Stopends & change of level units
Available in the PCT range and manufactured from heavy duty 2mm PP. Suitable if breaks appear in the natural run of the cavity tray system, and available in cavity size and rise options with 75, 150 and 225mm steps.

Radon sumps (RSUMP01)
Prefabricated sumps are required when a sub floor depressurisation is required under full radon protection. The sump is installed beneath the floor slab in non-suspended floor applications and vented to atmosphere via a connecting 110mm drainage pipe to an external source and capped off with proprietary products i.e. air bricks & telescopic under floor vents or roof vents.

Televent gas sleeve tray (TST01)
For use when telescopic under floor vents need to pass through a perimeter cavity and still maintain gas tight integrity. Threshold internal protection tray (TPT01) Designed for detailing rebated areas inside door threshold to maintain water and gas tight integrity without having to trim membrane to fit. Due to possible variations in size, threshold dimensions will be required.

Column cloaks (made to order)
Non-standard applications can require gas and water integrity around columns and stanchions. Timloc will design and produce rigid preformed units that are user friendly: simply contact our technical department.

• Timloc can prepare a comprehensive schedule and quotation service. Forward full working drawings and specifications to our technical department.
• Orders can be established from written quotations by stipulating number issued.
