How Does Radon Gas Enter Your Home....?
Radon Gas enters buildings
through small openings in the foundation. Since the building can hold
the radon similarly to smoke trapped under a glass, indoor radon
concentrations can increase to many times that of outdoor levels.
How Is Radon Levels Mitigated....?
The best method in reducing radon levels in the home is by installing a PVC vent pipe through the basement floor to force vent the radon gas below the slab to the exterior of the home. This method of radon reduction is known as "subslab depressurization." Typically, a hole is drilled through the basement floor and remove enough soil to create a pit (or a sump pit is used), then a PVC pipe is installed in the hole and properly sealed and finally routed to the outside. On the exterior of the home a fan is attached to the pipe to create suction to draw the radon from below the basement slab floor into the pipe, rather than allowing it to creep into the home. A differential water gauge is placed on the pipe to show that it is creating suction. The typical cost of a having a radon mitigation system installed range between $800 - $1,500.
