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.
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.
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.
