Hi
I understand from there should be 225mm of space in the cavity below the dpc. If not then in situ cavity trays should be used to direct any water to the outside via weep holes.
We have the following construction type - see diagram.
Is there a serious risk of water penetrating through the inner leaf under the dpc ?
The outer leaf is concrete block which is to be wet harled.
