Custom Spray-Foam on an Oil Storage Tank
2" closed-cell foam wrapped around a curved metal oil storage tank. No framing references — depth confirmed by hand throughout.

We handled this project just outside Moorcroft, about 15 minutes from the shop, which made mobilizing equipment quick and efficient. Short drive, full crew on-site, foam in the air before the morning was over.
The challenge: no framing references
Most spray-foam jobs have studs, joists, or rafters as built-in depth gauges — you know you're at the right thickness when the foam is flush with the framing. A round oil tank has none of that.
The foam sprayer worked methodically around the tank, applying material evenly and checking depth throughout the process. Since there were no framing references to guide thickness, handheld tools were used to confirm the foam stayed at the requested 2-inch specification. That kind of constant verification is the difference between a tank that performs to spec and one that has thin spots you'll never see.
Consistency on a curved surface
Consistency was key. On a curved metal surface, small variations can happen quickly — the gun has to keep moving around the cylinder at the same rate, the same distance, the same angle. Maintaining a flat, uniform finish required steady control and attention from start to finish.
Why this matters in the oil patch
This project also highlighted an opportunity in the surrounding oil-field region. With several tanks in areas like Moorcroft, Gillette, and Douglas, projects like this can be completed efficiently when planned in advance — get a few in a row and the mobilization economics get a lot better for the operator.
