I have recently seen on a bricklaying tutorial, the mention of a
requirement for a cavity tray at DPC level, along with weep vents at
regular intervals above the DPC. I've never noticed this in the regs
before, and assumed the cavity extending a distance below the DPC
would be enough for water running down to soak away.
The tutorial used an extra-wide DPC in the outer leaf and curled it
upwards. It looked like it was tucked into the inner leaf higher up. I
have seen this before, but never at DPC level.
Can someone confirm if I need a cavity tray at DPC or not ?
Thanks,
Simon.
