Waterproofing is the combination of materials or systems that prevents water intrusion into structural elements of a building or its finished spaces. Basic waterproofing and envelop design incorporates three steps to ensure a watertight and environmentally sound interior.
1. Understanding water sources likely to be encountered
2. Designing systems to prevent leakage from these sources
3. Finalizing the design by properly detailing each individual envelope component into adjacent components
