STANDARD SUB-SLAB DEPRESSURIZATION INSTALLATION

Standard Sub-slab Depressurization Systems are installed in homes or businesses with slab flooring. The radon mitigation system is made up of PVC piping and involves running the piping from the sub-slab radon collection point created to the fan that is mounted on the exterior, the radon gas is expelled from the building through the stack that extends past the roof line.

 

The system works by creating a negative pressure under the home where the radon collection point has been established, with this type of system there is one radon collection chamber. The radon fan that is mounted outside of the building 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 chamber under the slab the radon gas is collected and the systems fan will pull the radon gas from under the home out of the radon collection chamber and route the gas safely through the exterior piping where the gas exits the building out of the radon systems exterior 

INTERIOR SUB-SLAB DEPRESSURIZATION INSTALLATION

Interior Sub Slab Depressurization Installations are installed inside of homes or businesses usually to keep the system inconspicuous or not visable from the exterior of the establishment.

 

The system works by creating a negative pressure under the home. The radon fan that has been installed in the attic of the home or building runs continuously in order for the system to work correctly to mitigate the radon from the home or building. From the radon collection point under the slab of the home or business the radon gas is collected and the systems fan sucks the radon gas from under the home out of the radon collection point which routes the gas safely through the PVC piping up through the attic where the gas is removed from the home out of the systems roof stack installed through the roof of the structure.
