SteffanPE Posted May 17, 2022 Share Posted May 17, 2022 I’ve finished reducing the levels of my groundfloor, and ready to lay hardcore, concrete slab and then insulate before laying the UFH pipework. However i’m unsure how i should be dealing with the door threshold that is a cavity. As my concrete slab level is higher than the internal leaf. The required level for slab is top of wood in photo. How should i go about avoiding the cavity from being filled with concrete? And getting dpm fitted correctly. Link to comment Share on other sites More sharing options...
