Soil Gas Collector “T Riser” for 4″ schedule 40 PVC
Due to rising plastics costs, PDS has redesigned our famous T riser. This 4″ only riser saves time and money. PDS designs ALL gas mat systems for 4″ schedule 40 PVC unless otherwise noted. For a 6″ riser, see our older design here. 4″ risers are spread across every 2,000 sq ft of slab. 6″ risers across every 4,500 sq ft of slab.

The SGC T-Riser is a male end to 4″ schedule 40 PVC. Fit the 4″ schedule 40 around the pipe. Optional: use a dremel tool to cut off the fasteners to perf pipe or simply caulk and seal to ensure a tight fit before pour. After the concrete cures use a FF PVC connection to extend your PVC piping through the roof of the building. This unique design allows for a clean and easy connection and prevents excessive air flow resistance.
The system of the SGC matting and T-Riser very effectively streamlines the installation process during new home construction. This is very important for builders who have tight time constraints when working with subcontractors. Two people can install 200 L.F. for a 2,000 sq.ft. basement in less than an hour. The savings in time and labor is significant.
Radon Mat Install Guide
“T Risers” are installed approximately every 2,000 sq feet underneath the slab for radon-ready new construction in conjunction with Soil Gas Mat (SGM) to allow for radon gas to be exhausted safely.
New 4″ riser design has quickly become our most popular. For 3″ pipe, use standard PVC reducers after stubbing up 4″ PVC.
**Small changes should be made to fit 3″ or 4″ PVC. For example, for 4″, use a Dremel tool to remove the small triangular pieces on the vertical stub, then seal with caulk and fasteners. This small effort saves $50 versus other T RISER designs.**
Several alternate designs were introduced in 2020 in order to meet demand. Alternate designs are interchangeable and have all been tested to meet our standards. See photos or call for more details.
