Soil Vapor Mitigation


Soil Vapor SolutionsENVIRO TESTING has been actively involved in soil gas remediation since 1985. Over one thousand soil gas remediation systems have been successfully assessed, designed and installed in a wide variety of buildings including residential, commercial, industrial, churches and schools.

Reason for mitigation:

To reduce the level of dangerous soil gas vapors entering a structure to below EPA/ NYS DEC recommended levels.


Various methods are available and range from reduction of negative pressures, simple sealing of wall/floor cracks, crawl space venting, sub-slab depressurization, block wall depressurization and air/heat exchangers.


Sub slab communication testing is performed after installation of the sub slab vent system to guarantee negative pressures exist below the entire structure.
