Slab foundation building in Richland WA - firm, even support from the ground up
Building a home, addition or shop on a slab? We pack the ground and base first, so the concrete sits on even, stable support.
R&S Richland Concrete Construction is a concrete contractor based in Richland, working across the Tri-Cities and the cities around it. Homeowners call us for driveways, patios, steps and foundations, and property owners call us for lots and cutting jobs. Slab foundation building is work I like explaining as much as doing, because what goes under a slab decides how it holds up.
- Plain answers at every step
- Pours planned around the season
- Site cleaned up before we leave
What goes into building a slab foundation
Slab foundation building in Richland starts below the concrete. The slab is poured over a compacted subgrade, the packed soil it sits on, and a base layer above that, so it has even support from edge to edge. People call us when they're building a house, an addition, a garage or a shop on a slab, and if you need walls and deeper footings instead, that's our foundation installation work.
The price mostly follows the slab's size, how much digging and base the ground needs, the slope of the lot and how much steel goes in. The schedule turns on the season, the permit and the cure afterward, since the next stages of the build wait on the concrete. Your estimate puts all of that into numbers for your own lot.
- Digging out. We dig out the loose topsoil instead of raking it level, because a slab on loose dirt settles right along with it.
- Packed base. We spread and compact a base that drains well and stays firm under trucks and crews while the building goes up.
- Moisture barrier. A concrete trade group's guide advises a vapor retarder, a moisture barrier, directly under every indoor floor slab, so ask whether bids include one.
- Steel and forms. We set the forms for the edges and the rebar, steel bars that hold the slab together, before the truck arrives.
Slabs we pour for homes and shops
We pour slab foundations for whole houses and for smaller buildings, and the ground work under each one gets the same care. These are the jobs people usually call us about.
Home slabs
A full slab for a new house, with the ground dug out, packed and checked for drainage before any concrete is ordered.
Additions
A slab for a room added onto your house, set to meet the height of the existing floor and joined where it meets the old foundation.
Garage slabs
A slab for an attached or detached garage, reinforced for the weight of vehicles and sloped so water drains out the door.
Shops and barns
A slab for a shop, barn or outbuilding, built for the tools, equipment and storage you'll be putting on it every day.
If you're building something else on concrete, like a concrete parking lot or an equipment pad, call and ask us about it.
Why a slab foundation is worth doing right
The slab is the one part of the building you can't get back to once the walls are up. Getting the ground, the water and the pour right at the start gives the rooms above a flat, solid floor to sit on.
- Base before finishIf the budget gets tight, I'd cut somewhere other than the base, because nobody sees it on day one but it carries everything.
- Water runs awayWe check where water runs on your lot so the ground falls away from the slab, not toward it.
- Cooler pour timesWe avoid pouring in the midday heat, because a top that dries too fast turns weak and dusty later.
- Joints cut on timeControl joints, shallow cuts that give shrinking concrete a chosen place to crack, go in early so cracks don't wander where nobody planned.
How a slab job runs
I come out and measure
You call, and I come out myself to walk the lot, measure and talk through your options while we're standing where the slab will go.
Written estimate and plan
You get a written estimate that spells out what's included, and we plan the pour around what the job and the season call for.
Pour and walk-through
I'm on site with our crew from the dig-out to the finish, and before we leave I walk you through caring for the new slab while it cures.
Why people hire us for slab work
I'd rather you understand what's going under your building than just take my word for it. We explain each step as we go, and if you'd like to start with questions, call (509) 581-2407.
You see what you're paying for
I walk you through every line of the estimate, so you know what the base, the steel and the barrier each add before you decide.
An engineer when it's needed
When a slab needs an engineer's design, we bring one in and pour to those plans instead of guessing.
Satisfaction guaranteed
That's our promise, in those words, and I'd much rather hear a concern at the walk-through than have you wonder about it later.
Slab foundations in Richland and nearby cities
Permits for work in Richland, along with their inspections, go through the city's EnerGov permitting portal. When your slab needs a permit, we check with the office for your address, whether that's Richland, Kennewick or West Richland, and sort it out before work starts, telling you what to expect along the way.
Washington requires every construction contractor to register with the state Department of Labor & Industries, or L&I, and state law also requires them to be bonded and insured. We're licensed and insured, and it's worth confirming that anyone you're weighing meets the state's rules before you sign.

How much does a concrete slab foundation cost in Kennewick?
A reinforced concrete slab in Kennewick usually runs about $6 to $11 per square foot, before any staining or stamping. That's the going rate in the area, not a quote, and your estimate puts a figure on your own foundation.
Can a concrete slab be poured in cold weather in Richland?
Yes, if it's protected. Concrete guidance counts a pour as cold weather work when the air hits 40°F or is expected to drop below it, and with proper mixing, placing and protection the concrete still gains its strength. Frozen ground can freeze new concrete or let the slab settle after a thaw, so we tell you how we'll keep both from freezing.
When can I walk on a new concrete slab?
Usually within 48 hours, though concrete takes about 28 to 30 days to fully cure, which is the slow hardening that keeps going after it looks dry. To be safe, wait about a week before heavier loads go on it, and plan the next stages of your build around that.
How do I check if a contractor is registered in Washington?
Look the business up in L&I's Verify a Contractor, Tradesperson, or Business tool, where every registered contractor is listed. State law also requires contractors to put their registration number on estimates and bid proposals, so look for it on every bid you compare.
