​Vapor Intrusion

The movement of volatile vapors from contaminated soil or groundwater into overlying indoor spaces.  Vapor intrusion can occur when hazardous materials- petroleum products, solvents, dry cleaning constituents- are released to the environment.  Impact to soil and groundwater migrates via vapors that are not easily detectable via sight or smell.  Vapors can migrate through passages in your floor- openings around pipes, sumps, cracks, or pores in the concrete slab- and compromise indoor air quality.  Vapor intrusion is an urgent national issue and knowledge is constantly increasing around it. 

Vapor Mitigation

Depending on the concentration and types of vapors migrating into a building, a vapor mitigation system may be necessary to protect the health of the occupants.  There are two types of mitigation methods: Active or Passive.  Passive methods include:  sealing cracks, installing barriers, or below-grade venting.  Active methods include:  installing a sub-slab depressurization system, which mechanically vents vapors outdoors, and implementing structure over-pressurization, which involves adjusting building climate and ventilation to increase the indoor pressure relative to the sub-slab pressure.    
   

CUSTOM MITIGATION SYSTEM DESIGN & INSTALLATION

Vapor Control Solutions works with clients to design and install vapor mitigation solutions to meet their particular needs.  Vapor Control Solutions has installed vapor mitigation systems for a variety of structures- scales, uses, and aesthetics.
