Concrete contractor in Issaquah, WA - slabs built to drain and sit flat
Kirkland Concrete Company is a concrete contractor based in Kirkland that pours driveways, patios, walkways, steps and foundations for homeowners in Issaquah, with the digging, base and drainage worked out before the truck shows up.
How Issaquah's houses and yards shape a concrete job
Issaquah runs along I-90 at the south end of Lake Sammamish, and on our jobs there we mostly see two kinds of house. Near downtown there are older homes whose original driveways and walks have had decades to settle and crack. Farther out there are newer neighborhoods with wider driveways, patios out back and garage aprons that take a lot of traffic. It's much the same mix we work on over in Bellevue.
What ties them together is wet ground. Rain soaks in for most of the year here, so how a slab holds up depends on what's under it, and that's where an Issaquah job starts for us.
What we know from working in Issaquah
Inside Issaquah city limits, permits come from the city's Permit Center, which issues construction permits and land use permits, and the land use review checks that the work fits zoning and environmental rules. When your job needs a permit, I'll tell you at the estimate, and we take care of the application or walk you through it so you know where it stands. The pour date waits until it clears, so the permit and the weather are what your schedule really turns on. Your price moves with the size and thickness of the slab, how much old concrete has to come out and how much digging and base your ground needs. The free estimate is where I put numbers to your own job. We're licensed and fully insured.
Issaquah is a straight run down I-405 and I-90 from Kirkland, so I plan site visits and pour mornings around that drive, with the crew there and the forms set before the concrete truck pulls up. The same freeway takes us out to Mercer Island, where we do a lot of the same driveway and patio work. We cover the county areas around Issaquah as well as the city itself.
Why driveways and patios in Issaquah wear out the way they do
Most of the cracked, sinking and uneven slabs we look at here failed from underneath. Wet ground goes soft, so a slab poured on dirt that was only raked level sinks with it. A slab that slopes toward the house sends rain straight at your foundation. We dig down to firm subgrade, the soil the slab sits on, then bring in gravel, pack it and set the slope away from the house before a form goes in. That base work is buried on day one, and it's the first thing people want to cut from the budget. If money's tight, I'd rather you go with a plain broom finish, the light brushed texture that keeps a slab from getting slick, than skimp on what's under it. If your lot sits in an area the city counts as a special flood hazard area, let me know at the estimate, because that's worth settling with the city before we plan anything.
The other call we get a lot is for older front steps and walks that have tipped or crumbled after years of wet winters. When steps start to rock or chip, we usually replace them, because a patch on top of a step that's still moving tends to break loose again. Our page on concrete steps construction covers how we build them.

Meet me at your site
I come out myself to look at the ground and where the water runs, and to hear what you want. Then I walk you through the plan and give you a free estimate.
Get the permit sorted first
If the job needs a permit, we file it with the city or walk you through it. The pour date waits on the city's review, so this step sets the schedule.
Dig, pack and set forms
Our crew digs out, packs the base and sets the forms well ahead of the concrete truck, so pour day isn't rushed. You'll want the cars moved and a clear path for the truck and wheelbarrows.
Pour, finish and let it cure
We pour in the cooler part of the day so the top doesn't come out weak and dusty, and we finish the surface and cut the joints while it's fresh. Then it needs time to cure, the slow hardening that gives it strength, and I'll tell you when it's safe to walk and drive on.

Questions about concrete work in Issaquah
Do I need a permit to pour a concrete driveway or patio in Issaquah?
Plan on it, because the city says most improvements on a residential lot inside Issaquah need a permit. I'll tell you at the estimate whether yours does, and we handle the application or walk you through it.
How do I apply for a concrete permit in Issaquah online?
You apply through MyBuildingPermit.com, the portal the city uses for permit submittals and resubmittals, and city staff process what comes in there. If you'd like help, permit staff take appointments and answer calls at 425-837-3100, and the city's permitting page has the details.
Will my Issaquah concrete project need a pre-construction meeting with the city?
It might, since the city often requires a pre-construction meeting, especially on large projects. You can ask permit staff at CPD@issaquahwa.gov whether yours needs one, and if it does, we plan the schedule around it.
What building code covers a new slab or foundation in Issaquah?
Homes in Issaquah are built to the International Residential Code with city amendments, and the city notes its codes are also subject to Washington State amendments. Buildings that fall outside the residential code go under the International Building Code instead, so if your slab is for something other than a house, I'll check which one applies before we plan the footings.
How much does a new concrete driveway cost in Issaquah?
Your price comes from the driveway's size, its thickness and what's under it, and I give you a number at the free estimate once I've seen the site. Tearing out an old driveway, hauling in extra gravel for soft ground, adding drains or choosing stamped concrete over a broom finish all raise it, while a simple shape the truck can reach easily keeps it down.
What causes a new concrete driveway in Issaquah to crack?
Concrete shrinks as it dries and moves when wet ground under it settles, so some fine cracking is normal, and I won't promise you none. We cut control joints, grooves that give the slab a straight line to crack along, add rebar, the steel that keeps a crack from spreading apart, and pack the base so the ground doesn't drop out from under it.
