@thetopealao: DPC and DPM sound similar—but they don’t do the same job. Here’s the simplest way to remember: DPC → Protects your walls from rising ground moisture DPM → Protects your ground floor from ground moisture And where both are required, they should be properly detailed to help create a continuous moisture barrier. Building in a waterlogged or high-ground-moisture area? Don’t wait until dampness appears before thinking about moisture protection. Protect the building from the beginning.
