StormTech, Inc., Stormwater Chambers
Scope/Solutions
StormTech manufactures underground molded polypropylene chambers for stormwater retention systems. With no design standards available for these structures, StormTech asked SGH to assess the structural performance of the chambers and develop design procedures.
Polypropylene is a thermoplastic with excellent durability, but with time-dependent strength and stiffness properties. Highlights of our evaluation and analyses of the polypropylene chambers include the following:
- Adapted AASHTO design procedures for thermoplastic pipe to the evaluate of the chambers
- Conducted computer simulations under earth and live loading conditions
- Monitored full-scale field tests to evaluate performance under live loads and earth loads in excess of those anticipated during service
Based on our work for this project, SGH authored ASTM F2418 standardizing design criteria and laboratory test methods.

Additional Projects
Northeast
Jamaicaway Towers Parking Garage
P.J. Spillane engaged SGH to develop and design means and methods to provide temporary support while three columns supporting the three-level concrete garage structure were removed and replaced.
Northeast
Riverside Park Pedestrian Bridge No. P34
The bridge carries a pathway over the Charles River in Riverside Park, which is operated and maintained by the Department of Conservation and Recreation (DCR). SGH assessed the condition of the circa 1915 pony-truss bridge and was the engineer of record for the rehabilitation.
