On-site fueling for heavy equipment fleets requires concrete that contains spills, resists hydrocarbon attack, and supports tank loads with no settlement risk. Portland Concrete builds fuel station pads, containment areas, and tank pads engineered for environmental compliance and the actual loads your equipment imposes. Every project starts with a free written estimate.
A fuel area without engineered containment is a liability waiting to happen. Spills during refueling, slow leaks at fittings, and tank-area drips all need a concrete surface that contains them long enough for cleanup, with sealer that does not degrade under hydrocarbon contact and drainage that does not let fuel escape to the soil or storm system.
We engineer fuel station pads with containment curbs or sloped containment basins that hold a defined spill volume, hydrocarbon-resistant sealers rated for the specific fuel types handled, tank pads sized for full-tank weight on the worst-case soil, and the environmental documentation that supports tank-code compliance.
We confirm the fuel types handled (diesel, gasoline, def, etc.), the tank sizes and types (above-ground, below-ground), the required containment volume per environmental code, and any specific regulatory approvals needed.
Engineer pad and containment
The pad is sized for the heaviest equipment plus full-tank weight, containment curbs or basins engineered to hold the required spill volume, sealer matched to the fuel chemistry, and drainage designed to keep contained fuel separate from storm runoff.
Excavate, pour, contain
The site is excavated and based to engineered spec, forms set with containment geometry built in, reinforcement placed for the loads, slab poured with the containment cast as one monolithic structure rather than added later.
Seal and document
Hydrocarbon-resistant sealer is applied to the cured surface, the containment volume is verified, and environmental compliance documentation is delivered for tank-code review and facility records.
Why fuel pads fail
Sealer Maintenance Is Not Optional
Hydrocarbon-resistant sealer protects the slab from fuel attack but degrades faster than standard concrete sealers. Re-application on the schedule the manufacturer specifies (typically every few years) is what keeps the protection in place. Skipping the re-seal cycle means the slab eventually stains, then absorbs, then degrades.
We deliver the maintenance schedule with the project handoff and can return on the cycle to perform the re-seal as part of facility maintenance. Coordinate with adjacent wash bay work where both share environmental compliance documentation as part of our industrial concrete services.
Containment volume, hydrocarbon sealers, tank loads and environmental compliance.
Environmental code typically requires containment volume equal to the largest tank plus a percentage margin. We confirm the exact spec with your environmental officer or local regulator and engineer to that volume.
Hydrocarbon-resistant penetrating or topical sealers rated for the specific fuels handled. Diesel and gasoline have different chemistry; the right sealer matches the actual exposure with a margin. We spec based on your fuel inventory.
Yes, often. Tank pads are engineered to the tank weight and dimensions; the fuel station pad serves equipment access. Sometimes they are integrated, sometimes separate; depends on the layout and tank approach.
Yes. Containment volume verification, sealer specification, material specs, and as-built dimensions are all delivered at handoff for the facility's compliance file and any regulatory inspection.
Several weeks for design, engineering, pour, cure and seal. Larger fueling stations with multiple tank pads stretch longer. The full schedule is in the quote, including time for any regulatory review.

What Portland Operations Say About Their Fuel Stations
On-site diesel fueling for our fleet. Containment passes environmental inspection, sealer holds against the diesel exposure, tank pad shows zero settlement after two years of use. Right engineering.

★★★★★
Fuel station with both diesel and DEF, containment sized for both tanks. Compliance documentation supported our environmental audit cleanly. Real regulatory awareness.

★★★★★
Re-seal schedule was in the project handoff. We followed it; the pad still looks new four years in. Maintenance side mattered as much as the install.

★★★★★
Fuel station for our farm equipment fleet. Sized for our tank, contained for the spill volume our code requires. Inspector signed off without questions. Compliance done right.
