Hi I am extending at the side of the house up to an existing solid 9" brick wall. The wall has a DPC but due to sloping ground my FFL will be 440mm above it. I will go for 65mm Screed on top of 100mm concrete but that leaves me with 275mm to make up. How should this be done? Do I just use extra thickness of insulation with the DPM running up the side of the wall to FFL?
The ground on my side is currently just about level with the DPC.
