What Solidification Products International does

Solidification Products International, Inc. (SPI) is a privately held, veteran-owned manufacturer founded in 1991 by Bill Gannon and headquartered in Northford, Connecticut. The company designs and produces patented oil containment and spill prevention products that allow rainwater to drain passively while automatically sealing upon contact with hydrocarbons. Its core technology is a patented three-layer filtration media system that removes oil sheens to non-detectable levels (<1 ppm TPH) without sensors, pumps, or valves, supplemented by polymer-based solidifier chemistry (Oil Bond®), geomembrane secondary containment liners (XR-5), and a passive fire-quenching grating system for transformer pits (StoneQuench™ LHD®).

SPI's product portfolio spans drain fittings (Petro-Plugs®), sloped drain-pipe filters (Petro-Pipes®), high-volume gravity-fed sump filters (Petro-Barriers™), pump-assisted high-flow systems (Pump-Thru Barriers™), stormwater variants, and complete integrated containment systems. Products are custom-specified for each facility and manufactured at the single Northford facility. Revenue is generated through direct enterprise hardware sales plus custom system design services, with quote-based pricing and no disclosed public list prices. Distribution is direct (phone and website inquiry), with no channel intermediaries, and the company offers free consultations.

The customer base spans electric utilities and hydroelectric power plants (primary segment), military and government installations, industrial and manufacturing facilities, solar and wind farm operators, and a broadening set of newer verticals including data centers, battery storage (Tesla Megapack), mining, food & beverage, and transportation. SPI is ISO 9001:2015 certified, holds multiple U.S. patents and registered trademarks, and its products are explicitly accepted under EPA SPCC, SWPPP, and FRP regulations. In 2026 the company was named 'Oil Containment System of the Year' by Energy Business Review.
