Damp proofing

Damp proofing is essential to prevent external water penetrating the interior of a building which can lead to structural problems and have a negative effect on the health of occupants. Cavity trays can prevent damp and are required for roofs, walls and flooring to meet Building Regulations, NHBC Standards and BS 8215.

Cavity trays

Glidevale Protect’s comprehensive range of cavity trays offers a full solution for use in brick, block or random stone external masonry walls to prevent rain from penetrating external walls in accordance with British Standards and the NHBC. Our trays incorporate an array of features and benefits for ease of installation. They are specifically designed with all components being pre-formed or pre-creased to avoid inadequate installation and the issues most often found with conventional sheet DPC materials which can be difficult to form on-site.
