ABSTRACT:
A radon gas home/building mitigation method that reduces a home's/building's high radon level to a value that is within the recommended "safe" range. The mitigation method works by removing radon gas from the soil that is in contact with points of entry in the home/building, namely the homes slab, footer and below ground block that is connected to the footer. The method uses a hydraulic press/impactor to drive sections of threaded and perforated pipe under a home's/building's entire slab and footer. The pipe is made of sufficient length by threading and bonding numerous such pipes together. During the hydraulic press operation, each section of pipe has a tipped bit connected to its lead length and an impact sleeve connected to and disconnected from each end that is subjected to contact with the hydraulic press. After all the pipe sections are in place, each of the sections are interconnected at one end to each other and several vents. Each of the sections are interconnected at their remaining ends to each other and an automatic timer controlled fan(s) or wind turbine(s). The fan(s) create a vacuum in the pipe and cause the radon gas in the soil to be drawn into the pipe through its perforations and exhausted to the outside air where it quickly dissipates.
