Damp Proof Course

See DPC - a horizontal moisture barrier built into masonry at low level to prevent rising damp. In extension construction the new DPC must be connected to the existing house DPC at the same level. Extensions built above the existing DPC level can result in moisture bridging if not correctly detailed.
