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.
