Vapor intrusion mitigation protects a structure from vapors produced by subsurface chemical contamination in the ground below. It shields your occupants’ health. Vapor intrusion occurs when chemicals in soil or groundwater migrate out of the ground to contaminate indoor air in a structure above. These vapors may include:
Typically, vapors enter a structure by way of its foundation, through cracks from settling, gaps around plumbing and utility lines, or even through the pores of the concrete itself. Vapor intrusion poses a risk for anyone breathing the contaminated air. Health risks can be immediate or long-term depending on the chemicals, the vapor concentration, the amount of ventilation, and how much time people are exposed. In rare cases, vapor buildup from chemicals such as gasoline can create a risk of explosion. Because of these dangers, vapor intrusion is a significant environmental issue that has become a matter of concern for regulators as well as real estate developers, insurance carriers, building owners, and structure occupants and residents.
Vapor intrusion may be a significant environmental issue for building owners, designers and residents. We can assist with risk-based evaluation and design the appropriate system to prevent vapor intrusion. The Liquid Boot systems have proven performance and an extensive track record. These systems reliably provide protection from potentially harmful vapors.
All Liquid Boot systems are inert spray-applied, water-based products which contain no volatile organic compounds (VOCs). When cured, they form a continuous self-healing membrane with superior chemical resistance properties, preventing contaminated soil vapors from entering the building.
