Concrete and metal pole barns
Slabs, driveways, sidewalks and metal pole barns, plus our own dump trailer for the dirt and gravel. Based in Seminole, working all over Oklahoma.
From the dirt work to the doors
One crew hauls the dirt, sets the forms, pours the slab and puts up the building.
Estimates are free. Call, tell us what you have in mind, and send photos if you can.

How a job goes
A barn on a new slab, start to finish. Swipe or use the arrows.
-

First, the dirt
Our dump trailer brings in fill and gravel and hauls off what comes out. The pad gets graded flat.
-

Then the forms
Boards and stakes set the edges and the height. Plumbing and anything under the slab goes in now.
-

Pour day
Vapor barrier and steel go down, then the concrete. Some pours run under work lights.
-

The barn goes up
Posts, framing and steel siding, built square on the slab.
-

The floor goes in
Inside a pole barn we pour and finish the floor right under the trusses.
-

Doors and apron
Roll-up doors, a walk door, and a concrete apron so the mud stays outside.
-

Ready to use
Room for the tractor, the trailer or the truck, right next to the pens.

What should I have ready?
The kind of project, where it is, about how big, your budget, when you'd like it done, and anything special about the site. Photos of the area help most.
What does an estimate cost?
Nothing. Estimates are free.
How far will you travel?
We're based in Seminole and take jobs all over Oklahoma. Tell us the town or county when you call.
Can you do the dirt work and hauling too?
Yes. We haul with our own dump trailer, so fill, gravel and haul-off can be part of the same job.
Can you pour the slab and build the barn on it?
Yes. Concrete and metal pole barns are both what we do, so one call covers the whole building.
Are you insured?
Yes. Trejo's Construction LLC is fully insured.
