A systematic approach of arresting and reducing the flow of water within a cavity wall prior to any change in status of that wall helps balance demands on damp protection measures. In the case of a circular window passing through a curved cavity wall, protecting against damp ingress is easily achieved using a preformed Type K cavitray. The preformed Cavitray is curved to match the wall. Conventional flat material or roll material cannot uniformly match the radius of a wall.

The forming of a level threshold would be easy if the designer did not have to consider the prevention of damp ingress. The problem is a number of elements converge at a threshold, and when the threshold is required to be practically level, it can be difficult to bring together protective measures in a manner that promote integrated functionality and structural convenience. A different approach to forming level thresholds is offered by Cavity Trays Ltd. It literally and physically covers the problem. The Type LTT Level Threshold Tray is a three-dimensional preformed DPC that envelops opening masonry skins.
