Transformer Oil Containment & Secondary Containment Coatings
We line transformer oil containment pits, curbs and basins at substations, power plants and data centers, plus generator fuel and chemical containment, so a leak stays where it belongs.
Why Do Transformer Pits Need a Containment Coating?
Oil-filled transformers sit over a concrete pit, curb or basin meant to catch the oil if the tank leaks or fails. Bare concrete is not enough on its own. It cracks, shrinks and has joints and penetrations, and oil and water find every one of them.
We seal the floor, walls, joints and penetrations into one continuous lining that bridges cracks and moves with the concrete. The containment design belongs to the owner's engineer and the facility's spill plan (SPCC). Our job is to make the structure hold oil, working within your outage and safety rules.

What the Lining Does
Bridges cracks
Flexible, crack-bridging linings move with the concrete, so a new hairline crack does not become a leak path.
Seals joints and penetrations
Corners, cold joints, conduit and drains are detailed as part of the same lining, not left as weak spots.
Resists the fluid on site
We confirm resistance to your specific transformer oil, diesel or chemical before choosing the lining.
Holds up outdoors
UV-stable topcoats protect exposed curbs and walls from sun, rain and temperature swings.
Easy to inspect
A light, uniform surface makes cracks, staining and damage easy to spot on routine inspections.
Fuel and chemical containment
Generator fuel dikes, day tank areas, chemical storage curbs and battery rooms get the same careful detailing.

FAQ
Transformer Oil Containment Coatings Questions
Why isn't bare concrete good enough for a transformer pit?
Concrete cracks, shrinks and has joints and penetrations. Oil and rainwater move through those openings over time. A continuous, crack-bridging lining keeps the pit tight so it can hold oil until cleanup.
Does a coating make my facility compliant?
Not on its own. Compliance comes from your spill plan and the containment design set by your engineer. The lining makes the structure capable of holding oil, which is what that plan relies on. We work from the engineer's drawings.
Can you line a pit that already has stone and old oil in it?
Yes. We remove the stone, pump out water, clean or remove oil-soaked concrete, repair cracks, line the pit and inspect it before the stone goes back in. The pit comes back clean, sealed and ready for service.
Can you work at an energized substation or operating data center?
Yes. We work under the owner's safety program, outage plan and escort rules, and schedule pits and curbs around the access windows you set. Nothing starts until your team has signed off on the plan.
How much does a containment lining cost?
It depends on the number and size of pits and curbs, whether stone and old oil have to come out, how much concrete repair is needed, the fluid being contained and your outage windows. We return a full bid within 24 hours of receiving plans, so send yours or request a site walk.
