So I have a timber frame with an outer block and render skin.
Our external finished ground is going to be level with the slab (including channel drains at every opening).
MBC have installed their DPC under the sole plate and lapped it down to the ring beam that supports the blockwork (see image below).
I think I've gleaned that standard practice is then to add a second DPC 100-150mm above the external ground level and lap it down onto the frame DPC. Does that sound right?
However, where I'm confused is where to put the weep vents? If they go at the bottom then they will be blocked by the external ground. If they go at the higher level then the lower section could just fill up with water.
I'm beginning to to think I've got this detail all wrong?
