Union Gap concrete work, from older houses to shops
Union Gap sits right up against the south side of Yakima. On our jobs here we see older houses on settled lots, newer homes, and shops and small businesses close by. Our calls come from both, a homeowner whose driveway has dropped at the garage, or a business owner who needs a lot or a floor poured.
Most of what we pour in Union Gap replaces something that's already there, so the job usually starts with breaking out the old slab and seeing what it was sitting on.

Concrete services for Union Gap homes and businesses
Concrete driveway building
For Union Gap driveways that have sunk by the garage or split across the middle, we break out the old slab, rebuild the base and pour new.
Concrete patio construction
A back patio here often starts as a few pavers or a small stoop, and we pour a full slab that drains away from the house.
Stamped concrete services
Stamped concrete gives a Union Gap patio or front walk the look of stone or brick, poured over the same packed base as any plain slab we do.
Concrete sidewalk building
We pour walks from the driveway to the door with a broom finish, a light texture that keeps shoes from slipping when it's wet.
Garage floor concrete
Older garages around Union Gap often have cracked, oil-stained floors that have dropped at the door, so we replace the slab and set it to drain out.
Decorative concrete
Color, exposed stone or a scored pattern can dress up an entry or a shop front, and we talk through which finishes hold up best to foot traffic.
Concrete retaining walls
Where a yard steps down or a driveway is cut into a slope, a concrete retaining wall holds the soil back so it doesn't creep onto your slab.
Concrete floor installation
Shops and workspaces in Union Gap need floors that stay flat under carts and shelving, so we pour interior slabs with the base packed and joints planned.
Concrete pool decks
A backyard pool deck has to drain fast and stay safe underfoot, so we slope it away from the water and pick a finish that grips when wet.
Concrete steps construction
Crumbling front steps on older houses are a common call here, and we pour new ones with even risers, the height of each step, so they're easy to climb.
Slab foundation building
For a new garage, shop or addition here, we pour the slab foundation on a packed base, with the steel placed where the plans call for it.
Foundation installation
When a house, addition or outbuilding needs footings and walls rather than a slab, we dig, form and pour the full foundation to the engineer's plans.
Concrete parking lot building
Small businesses along Union Gap's busier roads need lots that carry customer cars and delivery trucks, and we plan the pour around your hours.
Concrete footings
Footings carry the weight of a deck, a porch, a wall or an addition, so we dig them down to firm ground before we pour.
Foundation raising
If a corner of your house has settled and doors stick or cracks run up the wall, we tell you straight whether raising the foundation is worth doing.
Concrete cutting
We saw-cut old concrete for a new doorway, a utility trench or a clean edge where a damaged section of driveway meets the part worth keeping.

What we know about working in Union Gap
Inside Union Gap city limits, building permits go through the city's Building Division. Many things decide whether a job needs one, so the city asks you to call 509-575-3638 about any project within its limits. Some addresses around here fall under Yakima County instead, so I check which office covers yours, and we don't set a pour date until the permit side is settled. Check two things on any contractor you're thinking of hiring. The state requires every construction contractor to register with Washington L&I, and the city requires a Union Gap business license for any business working inside city limits. We're licensed and fully insured, and we handle the permit paperwork for our part of the job.
The price depends mostly on what's under the old concrete and how much of it has to come out. After that it's the size and thickness of the slab, how close a truck can get, and the finish you pick. The schedule turns on the permit and on the crew's calendar. Your written estimate spells out the mix, the prep and what's included, so you can see where the money goes. Union Gap is next door to our base in Yakima, so getting a crew and a truck here is easy, and we do the same driveways, patios and foundations farther down the valley in Toppenish.

Why Union Gap slabs crack, sink and need replacing
Most of the cracked and sinking driveways we look at here weren't let down by the concrete. They were let down by the subgrade, the dirt and gravel the slab sits on, which got raked level instead of dug out and packed, so it kept settling and took the slab with it. The same jobs often have water pooling against the garage or running toward the house, because nobody checked which way the slab fell. We dig down to firm ground, pack a proper base and set the forms so water runs away from your house. You never see that part once we're done, and it's the last place I'd cut if a budget gets tight, because a fancy finish on a bad base still cracks.
Shop fronts, small business lots and driveways where someone parks a work truck take more weight than a patio ever will. For those we go thicker, add rebar, the steel bars that hold the slab together if it cracks, and cut control joints the day of the pour. Those are shallow grooves that give the slab a chosen place to crack.
How a concrete job runs when you call us in Union Gap
Here's how it goes from your first call to the day you drive on the new slab, and you'll know the price before we break any ground.
Call or send us a message
Call (509) 452-5002 or use the form, and tell us what you want poured and where. We get back to you to set up a time for me to come out.
I come out and measure
I come out myself, measure, look at the old concrete and the ground under it, and ask how you'll use the slab, so it helps if you can be there to walk it with me. You get a written estimate with the mix, the prep and what's included spelled out, so you know the price before anything gets broken out.
We sort out the permit
Once you say go, I check what the city or the county asks for, and we handle the permit paperwork for our part. The city says review can generally take up to 2 to 3 weeks, depending on how many applications are ahead of yours, and some jobs also need fire or utilities review. We set the pour date once it clears.
We dig, pour and clean up
Our crew digs out and packs the base, forms and pours, and I'm on site for the pour and the cleanup. Before we leave, we tell you when it's safe to walk on and when you can drive on it, because curing, the slow hardening that gives concrete its strength, needs time without weight on it.
Concrete contractor questions in Union Gap
Call (509) 452-5002Your price comes down to the size of the driveway, how much old concrete has to come out, how much base work the ground needs and the finish you pick. A plain broom finish costs less than stamped or colored concrete, and keeping the same footprint usually costs less than widening it. On any home job of $1,000 or more, a registered contractor has to give you the state's disclosure statement, so ask for it.
Keep it from sinking and choose where it cracks. All concrete cracks a little as it dries, and the goal is to keep those cracks in the joints and the slab level. That takes the packed base described above, water that drains away from the slab, a pour timed out of the midday heat so the top doesn't end up weak and dusty, and joints cut on time. Ask any contractor how they handle each of those before you hire them.
For most building permit applications in Union Gap, yes, the city requires plans. New structures and extensive remodels need detailed plan sets from engineers or architects. Small projects such as patio covers, carports or decks need simpler plans that an owner or a contractor can draw up. I'll tell you which kind your job needs when I come out.
If you build, extend or alter a structure, or change the land, in a mapped flood zone, the work has to fully comply with the city's flood rules. The city uses the flood zones mapped in Yakima County's flood insurance study, and you can see the maps at the city's Community Development office at 102 West Ahtanum Road. The permit application asks whether your property is in the flood area. Breaking the flood rules is a misdemeanor, so it's worth knowing before you plan the job.
You declare an exemption from the state contractor law on the city's building permit application. You also agree to hire only contractors who are registered and currently licensed in Washington for any labor or help. That means any crew you bring in for the pour still has to be registered with the state. If you'd rather not handle that, we take care of the paperwork for our part of the work.
Building work in Union Gap follows the International Building, Mechanical, Plumbing and Energy Codes as adopted and amended by the State of Washington. So the state's changes count, not just the national code. We pour to whatever your permit and those rules call for.

If you call before the old slab gets worse, the tear-out is usually smaller and there's less base to rebuild.
