Be Radon Ready

Build right the first time with Soil Gas Collector from PDS!

The world’s scientific community has concluded that there is no safe level of radon gas; therefore, the onus is on building occupants to ensure that the air they breathe is healthy and safe. Typically this is done by the homeowner or builder venting radon gas in a safe and effective manner.  With PDS’ proprietary soil gas collector (SGC), contractors, builders, mitigators, and, most importantly, homeowners can save time, energy, and money by building homes and commercial buildings “radon ready”.

Radon ready means that if a building is found to have radon gas inside, mitigation is simple.  A passive radon system has already been built, and by adding a radon fan a homeowner or mitigator can activate the system and bring the radon levels down further.

What is Soil Gas Collector?

Soil gas collector (SGC) is a semi-permeable hard plastic membrane that can withstand tremendous pressure.  It is placed directly on the “pad” or soil before a concrete foundation is poured.  When installed properly, the SGC creates an airway that bypasses the interior of the building and allows sub-slab gases (including radon) to vent safely to the outside air.  Passive systems give radon gas an “easy out”, however, radon can still enter the home through cracks and crevices.  It is still recommended that builders and homeowners test for radon at least once every two years.  If a high level is found, attach a qualified radon fan to the system and activate it.  This will usually bring radon levels down significantly.  SGC is extremely durable and can withstand work boots, wheelbarrows, and other common building site hazards.

What makes PDS’ SGC so special?

PDS’ soil gas collector is manufactured right here in the USA.  Competitors products are typically ½” thick, but PDS’ SGC is a full 1” thick.  This allows for the best sub-slab communication.

How do I know how much material I need?

Great news!  We’re just a short call away and can quote your project typically the very same day.  Send us your foundation plans so we can spec the SGC onto the drawings* for your records and send you a price quote at no additional cost!  When planning a job yourself, use the guidelines below:

SGC must run around the entire perimeter of the building.  It requires a “T-riser” to vent approximately every 2,000 sq ft.  T-risers often need a nail to keep them in place and SGC requires staples every 2-3 feet, especially if it will be down for a few days before the slab is poured, or it is installed in windy conditions.  For areas when SGC crosses or connects, there are a variety of connection types and builder preferences vary by region, please visit our products page to see more.

*We ask for 2-3 business day’s notice for complimentary foundation drawings; though often drawings are returned much faster.  Foundation drawings must be easily decipherable and sent as an uncompressed .pdf or .ai file.  Dropbox links or zip files will not be accepted.  Scale must be accurate and clearly notated.
