Cavity wall drainage duct
A cavity wall drainage duct or weep vent for discharging water from within a cavity wall construction comprises a hollow box section body (204, fig 3) having opposite open ends 206, 207 and a sloping internal base channel 212 that slopes down towards the external face of the cavity wall. Preferably the sloping internal case channel has a gradient angle of 2 degrees or between 1.8 degrees and 2.1 degrees. The cavity wall drainage duct may have a plurality of projecting ribs 211, 215 to reduce mortar slumping when the perpendicular joint in which the device is located is filled. Preferably the outlet opening is smaller than the inlet opening 207. The inlet opening may be the same height as a masonry brick.
