When selecting a waterproofing system, conservatism is the watchword. If leaks appear after the building is completed, the cost of excavation for repairs — even minor repairs — typically far exceeds the initial cost of the waterproofing system. Remember, as a designer you only have one chance to do it right. Research and due diligence are required to ensure that the right system is specified and all waterproofing issues are properly addressed. Site-specific issues and building requirements also necessitate proper consideration.
Waterproofing is the formation of an impervious barrier that is designed to prevent water from entering or exiting from various sections of the building structure. The waterproofing system is a series of integral components that function in unison to prevent moisture intrusion into the facility. The system configuration is generally similar in all waterproofing applications. The material components that are common to all types of waterproofing applications are the structural substrate, flashing, membrane and insulation.
