Bill Gannon, Founder and President Traditional oil containment approaches are designed to answer a single question, “Where will the oil go if equipment fails?”
Backed by more than 40 global patents and technologies, it has never recorded a single incident of oil escaping into the environment. Since entering commercial use in 1998, SPI has redefined what “fail-safe” truly means.
In 2002, an oil spill of approximately 300 gallons occurred at a site in New York. The Petro-Barrier solidified the oil into a rubber-like mass that was later removed and replaced with minimal material loss. The product has proven its worth at the utility through numerous incidents, including severe transformer failures and fires, reinforcing SPI’s early promise of fail-safe and field-proven protection.
Solidification Products International (SPI) goes beyond traditional containment design. Its patented systems are engineered to allow effective drainage under normal and storm conditions, remove trace oil and sheen during everyday operations, and automatically react to contain oil in the event of a catastrophic spill.
For utilities and energy operators, that shift changes everything. Instead of managing water levels, chasing compliance or hoping containment holds under stress, SPI gives them something far rarer—certainty. Renowned for manufacturing industry-leading oil-spill prevention products and solutions, SPI strategically controls spills, leaks and other issues.
“Many claim to achieve our standard of quality. But the reality is that delivering this high level of performance requires technology we’ve already patented and proven over decades,” says Bill Gannon, founder and president.
The effectiveness of the design has driven global adoption.
Effective Problem Solving
A persistent challenge for clients is groundwater infiltration. Routine rainfall and snowmelt steadily shrink the containment volume. Most drainage systems can’t move water at the high flow rates sites actually need.
SPI’s chemistry-driven oil containment systems, made in-house at its Northford, Connecticut facility, are powered by its patented filtering technology. They efficiently drain rainwater through proprietary media, while maintaining full containment capacity. If oil is present in trace amounts, it is easily removed by the system.
In the event of a spill, oil is instantly absorbed by the material, quickly forming a solid seal that stops all flow and fully contains it.
The media inside SPI’s products functions like a compacted filter cake— dense in appearance, yet engineered to allow water to pass through efficiently. Water moves through the filtration bed under natural head pressure, enabling steady, high-rate drainage and maintaining the containment’s full operating volume. Without effective dirt control, fine debris can accumulate on the surface of the media, slowing drainage and restricting flow. Managing dirt has always been a core design priority for SPI, ensuring consistent water movement without compromising containment performance.
Where Chemistry Becomes Engineering
SPI has engineered its core chemistry into a range of solutions.
Petro-Barriers, Petro-Pipes and custom-fabricated systems preserve containment volume, eliminate stormwater risk, and adapt to any soil, layout or site. All SPI products meet SPCC requirements.
Petro-Barriers are engineered for 100 percent oil containment in large areas, such as concrete or lined systems. They can be cast directly into concrete or installed in liner systems, featuring flexible discharge options that allow for either direct infiltration into suitable soils or lateral routing to dry wells. Depending on diameter, each barrier delivers 22 to 50 gallons per minute of clean water flow, protected by top-hat pre-filters that prevent sediment from entering the media.
The origins of its foolproof approach date back more than two decades. In the late 1990s, a major U.S. utility operating under an environmental consent order was struggling to stop oil from escaping its substations. The search led to SPI’s first Petro-Barrier installation in 1999 in one of its substations. For the next 18 months, the system was closely observed through rain, snow and changing conditions to confirm that water continued to drain as designed. The results prompted the client to consider a wider rollout across the utility’s unit substations, followed by installations at larger transmission facilities.

High-Capacity Drainage
For containment systems that rely on sumps and pumps, SPI offers the Pump-Thru Barrier, a portable, above-ground containment unit designed for rapid removal of high-volume of water. Rainwater is pumped into the barrier’s inlet and first passes through a pre-filter to remove dirt and debris, then through internal dirt and oil-sheen filters before reaching the SPI media canister, allowing clean water to flow at around 30 gallons per minute.
“In the event of a spill, any oil that enters the system is absorbed and sealed. The system automatically stops flow and diverts the oil back into the containment area via an overflow valve,” says Gannon.
Petro-Pipes, an integral part of a complete oil spill containment solution, are designed for rainwater discharge. A larger diameter Petro-Pipe installed at a 25° slope can achieve around 4 gallons per minute of drainage. To prevent water from accumulating within the containment area, installations are engineered with an adequate number of Petro-Pipes based on site conditions and drainage requirements. The units can be cast directly into concrete using a housing pipe. Afterward, the Petro-Pipe slides into place and is secured with stainless steel fasteners. A pre-filter basket is positioned in front of each unit to prevent dirt and debris from entering the pipe.
When containment areas are backfilled with stone, SPI incorporates a half moor gravel guard, a perforated protective enclosure ranging from 24 to 48 inches. . Rainwater filters through the perforations and flows toward the drainage system, while the gravel guard prevents stone and debris from obstructing performance. The design also allows operators to easily lift the cover and visually inspect the system, ensuring proper operation and simplifying routine maintenance.
“The effectiveness of the design has driven global adoption,” says Gannon.
Petro-Pipes are used by a German-based solar inverter manufacturer in every skid housing its inverters and transformers. After evaluating alternative solutions, the manufacturer selected SPI for its performance, reliability and completeness. The client integrates SPI technology into systems deployed worldwide.
In one instance, an elevated substation in Staten Island experienced a catastrophic transformer failure that resulted in a fire lasting over three hours. A network of vertically installed Petro-Pipes running through the containment floor ensured every drop of oil was held in check.
Purpose-Built for Real-World Conditions
Field-tested confidence became the catalyst for change. When many of its legacy patents approached maturity, SPI produced a series of new systems tailored to emerging installation challenges.
To accommodate installations that require specialized geometry, SPI custom-fabricates aluminum systems in-house. Recognizing the need for innovative solutions, it developed the Petro-Pipe Sump Box, a highly effective oil-containment system for efficient drainage. The system positions the Petro-Pipe within a sump angled at 25 degrees, ensuring that all water on the containment floor naturally flows into the sump. Inside, integrated dirt filters capture debris.
Equally impressive is the SPI Oil Containment Shield. It protects pad-mounted transformers holding up to 700 gallons of oil, making it especially ideal for smaller transformers located near waterways. Fabricated with coated bottoms to prevent corrosion, the shields can be customized for size and can address site-specific obstacles by adjusting sump dimensions. Manufactured as a single piece or multiple sections, it allows for flexible shipping and installation.
SPI’s Patented Petro-Plug Wall Box units are angled with a sump that is three-inches below the floor of the Oil Containment Shield. As rainwater enters the containment shield, it is directed into this sump, immediately creating full head pressure against the media at a rate of two to eight gallons per minute, while preventing any oil from escaping the system.
This innovation momentum has fueled significant operational growth, prompting SPI to expand its manufacturing and training capabilities. Since then, SPI has added multiple patents across the EU, Australasia and Canada.
SPI is committed to exceeding compliance rather than merely meeting it. While federal regulations permit oil concentrations of up to 15 parts per million, state and municipal standards are often more stringent. SPI sets its own bar higher, engineering systems to achieve discharge levels below 3 parts per million.
Future-Proofing with Continuous Innovation
SPI serves global customers. A major New York City utility undertook a multi-year initiative to support the transition to synthetic ester transformer fluids, which offer significantly higher flash points than traditional mineral oil and align with emerging environmental priorities. To meet this shift, SPI developed a new proprietary polymer, manufactured in-house and created in collaboration with the University of Connecticut. The resulting technology has since been approved by the utility for use across its oil containment systems. SPI is currently the only company in the world capable of delivering this patented solution.
SPI has also introduced advanced fire suppression capabilities by bringing proven European technology to North America.
SPI’s rapid growth has driven a major expansion of its manufacturing footprint. With demand increasing 12 to 20 percent annually, it is completing construction of an 8,000-square-foot facility dedicated to Petro-Pipe and media production, while repurposing its existing 9,000-square-foot facility for metal fabrication.
Another new building is planned with offices and a training center designed for customer demonstrations and SPI’s annual ‘Plug That Leak Day,’ where clients witness full-scale spill scenarios in a controlled environment.
Where every site is different, and every mistake is costly, SPI is the partner that provides engineered certainty—field-proven oil containment that never fails.
Rethinking Oil Containment For Modern Energy Infrastructure
Oil containment systems occupy a quiet but decisive position in energy and utility infrastructure. Substations, renewable installations and industrial facilities depend on them to prevent environmental release during transformer failures, routine drainage and extreme weather events. Regulatory scrutiny has intensified, public tolerance for spills has narrowed and infrastructure operators are under pressure to demonstrate that containment capacity is not merely theoretical but proven under stress. Executives responsible for acquiring oil containment systems must therefore look beyond basic bunding or passive pits and examine how a system behaves under rain load, debris accumulation and full-scale oil discharge.
Effective containment begins with water management. Rainwater that accumulates inside a containment area reduces available volume. If it is not drained efficiently, a transformer failure can result in overflow even when the containment footprint is technically compliant. Drainage cannot come at the expense of environmental protection. Systems that rely solely on mechanical separation or manual pumping introduce risk, particularly when oil sheen is present. The most credible designs allow rainwater to pass while blocking hydrocarbons automatically, without dependence on operator intervention.
Drainage performance must be evaluated alongside dirt control. Construction debris, concrete dust and windborne sediment frequently compromise outflow points. A system that does not integrate pre-filtration or sediment management will slow over time, undermining both compliance and capacity. Buyers should examine how the solution handles head pressure, how it prevents clogging and how it signals or reacts to hydrocarbon overload. Passive shutoff triggered by oil contact, rather than sensors or human oversight, reduces failure pathways.
Verifiable field performance remains essential. Laboratory claims are insufficient in a sector where a single release can trigger consent orders and long-term reputational damage. Executives should request documented spill history, evidence of regulatory thresholds achieved and proof that large-volume events have been contained without release. The difference between filtering light sheen and containing tens of thousands of gallons during a catastrophic transformer failure is substantial. Systems must be tested against both scenarios.
Solidification Products International presents a technology-driven approach shaped by these pressures. Its containment solutions are built around a patented media designed to allow rainwater to drain while removing oil sheen to non-detectable levels, then solidifying and sealing when exposed to significant hydrocarbon volume. Once oil contacts the media, it forms a tackified barrier that shuts off discharge, converting the outflow path into a sealed system. This automatic response addresses the core tension between drainage and containment without reliance on active controls.
Its Petro-Barrier units are engineered for concrete or liner-based containments and support varying flow rates depending on diameter, enabling designers to match rainfall conditions and basin size. Integrated pre-filters and top hat filters intercept debris before it reaches the media, reflecting an emphasis on dirt management that directly influences long-term performance. For retrofits where pumps are already in place, its pump-through barrier routes discharge through staged filtration and a media canister, returning oil to the pit if overload occurs. Field experience includes containment of both moderate spills and full transformer failures without reported escape of oil, including high-volume events at utility and renewable sites.
Executives evaluating oil containment systems must look for sustained drainage capacity under sediment load, automatic shutoff under hydrocarbon exposure and documented performance in real spill conditions. Solidification Products International aligns with that benchmark through patented media technology, configurable barrier systems and demonstrated full-scale spill containment. In an environment where compliance is measured by what does not escape, it stands as a disciplined and defensible choice.
