Urethane cement floors we put down
Self-leveling urethane cement
A smooth poured layer that levels itself out over the slab. It suits coolers, warehouses and dry production rooms where carts roll and floors get mopped.
Textured finish for wet rooms
A rougher surface made by spreading grit into the wet layer, so feet keep their grip when the floor's soaked. It fits wineries, breweries and washdown areas.
Is urethane cement flooring right for my plant or cooler?
Urethane cement flooring is a tough floor system we install over the concrete slab in Martinez food plants, wineries, breweries, coolers, freezers and warehouses, the working spaces where spills, hot washdowns and cold wear through ordinary coatings.
Usually the call comes because the floor is losing to the work, with old coating lifting by the drains, concrete pitting from spills or a cooler floor breaking up. It isn't a weekend project, since one maker says its urethane cement system is only for experienced professionals. The price moves with the square footage, how much old floor and damage has to come off, how many cracks need repair and whether you want a smooth or textured finish. The schedule turns on when you can shut the space down and how long the product needs before people and forklifts go back on it. I put your own price in a written estimate after I've looked at the slab.
Slab prep and the urethane cement install
I start with the slab and how you use the room. If it never sees spills, washdowns or cold, polished concrete flooring or stained concrete flooring may be the simpler fit.
Plan around your shutdown
We set install dates around the window your space can be shut down, so production loses as few days as it can.
Test the slab for moisture
We test how much moisture is rising through the concrete before anything goes down, because one maker's instructions require that test.
Grind and repair the slab
Our crew grinds the slab and repairs damaged spots and cracks, since the new floor holds only as well as the concrete under it.
Lay and finish the floor
Our crew lays the urethane cement, smooth or textured, and finishes it tight against walls and drains, where water tries to get under a floor.
Why Martinez businesses call Stonefield for floors
I taught myself floor coatings and learned the rest beside experienced crews, then started this business in Martinez in 2017. We're known for floors that stay bonded because we put our time into the slab first. Call (925) 231-8429 to set up a visit.
The owner on the job with the crew
Our crew does the prep and the install, and I'm on the floor with them, so the person who looked at your slab is there while it's done.
Licensed and insured for prep and install
We're licensed and fully insured. California's licensing board counts getting the surface ready as part of a flooring contractor's work, and that's where we put most of our time.

Before you sign anything, I tell you what we'll do to your slab and why, in plain words. Satisfaction guaranteed.

Urethane cement flooring questions in Martinez
How much does urethane cement flooring cost in Martinez, CA?
Installed urethane cement flooring in California usually costs about $11 to $20 per square foot. Where your floor lands in that range comes down to the prep, repairs and finish covered above, and I'll put your own figure in a written estimate after I see the slab.
How long does urethane cement flooring take to cure before we can use the space?
One maker's data sheet lists foot traffic after 12 hours, vehicle traffic after 24 hours and full cure at 7 days. Times differ by product, so we tell you the times for the one we're putting down and you can plan your closure around them.
What causes cracks to show through a new urethane cement floor?
Cracks and joints that still move in the slab underneath cause it, and one maker says they will show through the finished floor. We repair what we can, but if your slab has moving cracks, I'll tell you before we start that those lines will stay visible.
Does a food business in Martinez need county approval before replacing a floor?
Yes, the county health department lists replacing or installing a floor in a food facility among the projects that need plan review, and no work may be done before the plans are approved. We set the crew's start date after that approval comes through.
Does urethane cement flooring change color in sunlight?
It can, because one maker says its urethane cement floor isn't color stable unless a UV resistant topcoat, a top layer that holds up to sunlight, goes over it. If part of your floor gets sun through a dock door or windows, bring it up at the estimate so the topcoat is part of the plan.
Can urethane cement flooring go over an old epoxy or painted floor?
Not over the old coating itself, because one maker's instructions say the concrete must be clean and sound, with paint films, oil and grease removed. Our crew strips it and grinds down to bare concrete before anything new goes down.

A lot of the floors we're called to here sit in wineries, food plants and cold storage, where the county's plan review covered above comes first, so we hold the schedule until you're cleared. We do the same work in Benicia and Concord, and across Martinez and the cities around it.
