Defining DPC and DPM
A Damp-Proof Course (DPC) is a horizontal (and sometimes vertical) protective layer, typically placed in a wall above ground level to stop moisture rising from the foundation or external soil into the wall structure. It often appears as a thin layer of impervious material—like bitumen polymer or plastic—sandwiched within the mortar line.
Meanwhile, a Damp-Proof Membrane (DPM) is used to cover larger surface areas, primarily floors, and sometimes walls. Think of it as a sheet or film laid beneath or across the building slab or screed to block water migrating upwards from the ground. Some DPMs can also run up walls, forming a continuous “bowl” that ensures water beneath the slab can’t enter the building fabric.
Both solutions work on the same fundamental principle
