Damp Proofing



Type E Cavitray

Available in 6 variation(s).

Use
To introduce a horizontal DPC at roof intersection level in an outside wall which has become an inside wall, by virtue of an extension being built.

Introduction
The Type E is a preformed DPC cavitray which is inserted into an existing cavity wall. The Type E requires only one course of bricks to be disturbed, with just a few bricks removed at any time. The self-contained Type E cavitrays are the length of two bricks, and clip together, so long runs are easily and quickly created. Preformed angles cater for corners and piers. Each unit has stand-alone discharge via a weep. Suitable for all popular cavity widths because the cavity upstand of the Type E is hinged and adjusts to always suit the ‘as-found’ cavity width.

Data

  • Standard two length cavitrays with integral perp upstands.
  • Material - solid DPC polypropylene.
  • Positive jointing integral anticapil clip eliminates gluing, sticking or overlapping.
  • Shape and depth of projecting lip prevents discharge water permeating the bedding joint - an often overlooked consideration on exposed sites.
  • Adjustable cavity upstand accommodates cavity size 50mm to 140mm.
