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 mat (SGC) sometimes referred to as “vapor mat”, contractors, builders, mitigators, and, most importantly, homeowners can save time, energy, and money by building homes and commercial buildings “radon ready”. In the industry, we call it radon ready new construction or RRNC for short.
RRNC means that if a building is found to have radon gas inside, mitigation is simple. A passive radon gas mitigation system has already been built, and by adding a radon fan a homeowner or specialist can activate the ventilation system and bring the radon levels down further.
What is Soil Gas Collector Mat?
Soil gas collector mat (SGC) A.K.A. vapor mat 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 vapor mat creates an airway that bypasses the interior of the building and allows sub-slab gases or vapor (including radon) to vent safely to the outside air. Passive RRNC systems give radon gas an “easy out”, however, radon can still enter the building 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. These radon gas mitigation systems will usually bring radon levels down significantly. Soil Gas Collector Mat is extremely durable and can withstand work boots, wheelbarrows, and other common building site hazards (up to 3,000 PSI).
What makes PDS’ SGC so special?
PDS’ soil gas collector mat is manufactured right here in the USA. Competitors products are typically ½” thick, but PDS’ SGC is a full 1” thick (as stipulated in the ASTM International Guidelines). This allows for the best sub-slab communication. Our 1″ thick mat has the same airflow as 4″ schedule 40 PVC perforated pipe, all while being low profile, making it a perfect fit for RRNC. Soil gas collector mat does not need gravel to be effective either, which will significantly cut costs when compared to perforated pipe.
How do I know your material is an approved method of depressurization?
ASTM international Guidelines list Soil Gas Mat as an approved method for Radon Ready New Construction (see pages 9-10 here). Most states and municipalities have no regulations for RRNC. Those that do all approve of Soil Gas Mat (with some variations in recommended installation). For more details, call PDS or your local regulatory agency. Colorado, for example, recommends but does not require soil gas mat for RRNC.

How do I know how much material I need?
Great news! We’re just a short call away and can quote your radon gas mitigation project typically the very same day. You can also fill out THIS FORM and we will email you a quote ASAP*. When planning a job yourself, use the guidelines below:
SGC vapor mat 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. Architects, see our sample drawing below.
What about footers and trenches?
PDS has designed a steel sleeve in order to go through footers and span trenches. Simply thread the mat through the sleeve and pour concrete. Saving time and money. 24″ long by 1″ high by 12″ wide.

I’m an architect. How much Mat do I use?
See the sample drawing and video:
Soil gas collector goes around the perimeter of the building. T-riser exhausts are placed every ~2,000 sq ft of slab. T-risers are typically hidden in chases and mechanical rooms, as “activated” systems create air noise that can be heard by occupants (always try to keep exhausts out of bedrooms). For very large buildings, runs of mat can be added every 3,000-4,000 sq ft. Many architects use too much mat on their first drawing which not only wastes material, but in some cases can make the systems less effective.
