hi i need help, im about to build my own extention and im about to roll out the DPC and bed it down.

My question is, after laying the DPC do i need to put in a cavity tray at that level aswell ???

any help will be appreciated, thanks

knocka007,
If you are building cavity walls and you have filled the cavity below ground to within 2 courses of the DPC there will be not need for a cavity tray.
