Hi all im in the process of building an extension, I have got as far as the dpc course and I'm curious as to how I join/overlap the new extension dpc to the existing house dpc.
Also I'll be putting in a vertical dpc running down the house, once I've cut roughly 40mm down the wall of the house how do I finish off the last bit of cutting down to the house dpc..
Plus how do I attach my cavity tray to the house? I have got stop ends specially made.
Thanks all
