Garage Attic 2nd Tap Radon Mitigation Installation

Subslab depressurization Garage Attic 2nd Tap Installation - Diagram of the system installation and a brief overview on how the radon gas mitigation system functions to remove radon gas from your home or establishment.

2nd Tap Sub-slab depressurization systems are installed in homes or businesses with slab flooring and are necessary in situations where a single tap or collection point is not adequate enough to bring radon levels in the establishment down to safe levels. This is either due to the amount of radon gas found in the the location or due to the soil found underneath the establishment. The radon mitigation system is made up of PVC Piping. A garage attic installation with a 2nd tap involves running the piping from the sub-slab radon collection points created in the slab to the garage where you will find the radon mitigation fan installed in the attic of the garage. From the fan there is a roof stack where the radon gas is expelled from the building. This is a common practice for homes that need more power or collection points to help mitigate the radon from underneath the home or business.

The system works by creating a negative pressure under the home where the radon collection points have been established, with this type of system there are 2 collection points instead of just one. The radon fan that is mounted in the attic must run continuously in order for the system to work correctly to mitigate the radon from the home or building. From the 2 radon collection points under the slab the radon gas is collected and the systems fan will suck the gas from under the home out of the radon collection points and route the gas safely through the PVC piping up through the garage attic where the gas exits the building out of the installed roof stack. This method isn't quite as common as a single tap system and is only needed in severe occurances and depending on the radon level or radon gas situation.
