Damp proofing is a system of control which prevents moisture from passing through walls and floors into interior spaces. It increases moisture resistance, but does not completely prevent water from entering the surface. Waterproofing is a more complete method of resisting moisture as it stops water seepage caused by hydrostatic pressure, which is the rising of ground water into your surfaces. Damp proofing uses materials like tar. Waterproofing is more environmentally friendly and uses materials like rubber.
