Passive Systems and New Construction Homes

In most cases passive radon systems are installed during the construction stage of newly built homes. All new homes should have a passive radon system.  A passive radon system includes a pipe fitted into the slab prior to the slab being poured. This is done so the passive piping will have good access to the radon air under the slab. The pipes required for a radon system can be built into the home and a small stack on the roof is an excellent alternative to possibly running a stack on the outside of the home.

Depressurization Systems:

A 4" hole is cut into the concrete slab. A cavity is created into the soil below. Piping is then installed into the hole and a mitigation fan is used to draw radon as well as tougher soil gases from beneath the slab and exhausted safely above the home.

Crawlspaces: Sub Membrane Depressurization

Piping with perforations is laid on the dirt or gravel inside crawlspace, and a 6 mil plastic sheathing is placed over the entire crawlspace area. The piping draws the radon from under the sheathing.

Garage and Attic Installations:

In some cases it is possible to run the radon piping up through the house or garage and into the attic above.

Exterior Installations:

With slab on grade homes or walk out basements it may be possible to install a radon system entirely on the outside. This is a useful method when your basement is finished and you may not want piping inside your basement area.

Other Considerations:

Sump pumps, floor cracks, perimeter cracks and condensation drip points all must be sealed. Furnace drip line should be fitted with 6" condensate drip tube. A gauge to measure system performance will be installed.
