Horizontal Perimeter Cavity Tray 2.5m x 150mm Rise
Radon, methane, CO2, hydrocarbon, vapour & DPC cavity tray.
Works in conjunction with radon, methane, CO2 and hydrocarbon gas barrier systems to contain rising gases across the footprint of the building.
Preformed mouldings eliminate the need for site fabrication to prevent errors through poor workmanship. Easy to handle, flexible, tough, durable and puncture-resistant.
Can be used for multi-storey or high-loading applications and will not extrude under high loads up to the point of compression failure of the wall.
As with DPC, accessories should always be bedded onto the fresh mortar, never dry bedded. The masonry laid over the DPC should also be bedded onto fresh mortar so that the DPC is approximately halfway through the thickness of the mortar joint. DPC must be lapped onto the accessory by a minimum of 100mm.
All lapped joints must be fully sealed with jointing tape. It is essential that the joining surfaces are clean and dry or the jointing tape will not seal correctly.
No building materials included.
