This Type E preformed DPC Cavitray can be inserted into an existing cavity wall and requires only one course of bricks to be impacted with just a few bricks removed at any time.
This self-contained Cavitray is the length of two bricks and can simply clip together with another Cavitray, so you can quickly and easily create a long run. With preformed angles catering for piers and corners, it has stand-alone discharge via a weep. It is compatible with all common cavity widths, thanks to its hinged cavity upstand that can adjust to always fit the 'as-found' cavity width.
Ideal for preventing damp penetration from an original external wall that has become an internal wall due to an extension being built, this Cavitray can also re-establish damp control measures where an original DPC has failed.
