Radon Mitigation

Active Soil Depressurization Interior Installation
The EPA's most recommended method for radon reduction. It has proven successful in small residential homes as well as large, multi-story buildings. Its long range success is dependent upon the quality of the installation and the design reflecting the construction characteristics of the building. Radon reduction is achieved by generating negative pressure under the slab floor.

Active Soil Depressurization Exterior Installation
Similar to the interior system except that the piping is placed on the exterior of the building. The design of this system requires a thorough knowledge of construction and building techniques to insure that damage is not done to the foundation or the plumbing and electrical systems of the building. In most cases the exterior piping can be designed to blend esthetically with the exterior appearance of the building. This type of system is generally used when construction features prevent the installation of an interior ASD system.

CRAWLSPACE Sub-Membrane Depressurization
This system is used when buildings with crawlspaces below them do not provide enough natural ventilation to neutralize the radon gas emanating from the soil. A durable membrane

Commercial Mitigation Applications
Installation of radon mitigation systems in commercial buildings require a more in-depth knowledge of construction and building techniques. The basic theory of radon reduction is the same as that applied to residential buildings. But since building codes and construction designs are much different, the mitigation contractor must be thoroughly knowledgeable of building codes and construction practices to avoid damaging the structure or violating the building's structural integrity. Often commercial builders of apartments, nursing homes and office buildings incorporate Radon Resistant Building Standards into their buildings during construction

Pre-Construction Radon Prevention
The US EPA and the states of Florida and Colorado have produced technical guidelines or recommended standards for Radon Resistant Construction Techniques for new residential and large building construction. These guidelines and standards are currently employed in many large and small construction projects throughout the US. The systems, if installed properly, can help eliminate the potential for high levels of radon in a completed building.

Mechanical Ventilation
Mechanical ventilation is most commonly used in the southern part of Florida, in multi-family apartment and condominium communities. This system brings in a balanced amount of outside fresh air which serves to dilute the radon gas to below the EPA action level of 4.0 pCi/L while generating a slight positive pressure inside the apartment. The slight positive pressure prevents the entry of radon gas from the slab penetrations.
