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 also has an ABS riser attached to it, which extends above the top of the concrete floor. Note that the future pipe opening is sealed to prevent wet concrete from entering the collection box.  After the concrete cures, a simple cut reveals the opening into which a 4 inch PVC pipe can be connected. This unique design allows for a clean and easy connection and prevents excessive air flow resistance.  T riser can also be cut to allow for 6″ schedule 40 pipe to be inserted instead of 4″.

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.

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.
