Radon is typically reduced by installing a system that creates a vacuum beneath the structure which is larger in strength than the vacuum applied to the underlying soil by the building itself. This method (active soil depressurization) collects the radon laden soil gases before they enter a building and exhausts them to a safe location above the building.
The success of this approach depends upon the ability to draw air from beneath the foundation, which in turn is dependent upon soil permeability, obstructions, such as grade beams, and foundation walls. The proper location of a suction point is critical in developing a cost-effective approach.
The evaluation of a building’s HVAC system is also critical in developing possible solutions to the mitigation of the effects of radon gas. Many times an adjustment to the building’s HVAC system can alleviate elevated levels.
CVC is experienced in performing the diagnostics to determine solutions for mitigation as well as designing a system and/or plan that will be the most cost effective and create the desired results.
Elements of a CVC Radon Design:
- Provides clear interpretation of radon results survey
- Provides steps and a time table for remediation
- Provides cost-estimates for repair
- Represents a clear and responsible approach to radon
- Can save capital and operating costs
- Can often be implemented by maintenance staff
- Can be used as a basis for bids from local contractors
- Can be passed on to future building owners for implementation if radon has become an issue at the time of sale.
