Damp proof membranes are essential components in modern construction when protecting against moisture ingress in floors and walls. Typically made from high-density polyethylene (HDPE) or bitumen-based compounds, these membranes act as barriers that prevent ground moisture from rising into concrete slabs, screeds, or internal surfaces.
