Groundbreak Redmond Concrete Company is a concrete contractor based in Redmond, WA, and we pour driveways, patios, garage and shop slabs, steps and retaining walls for homes in Maltby. We look at the ground and where the water runs before anyone talks about the finish, because that's usually where old concrete went wrong.

Maltby sits north of Woodinville where SR 522 meets SR 524, and the properties we work on up here usually have more room than lots closer in. That means long driveways and turnarounds, detached garages and shops that need a floor, yards that fall away behind the house, and now and then a business owner with a lot or a walk to sort out. A long driveway on soft ground has more places to settle than a short one, so the first thing I ask about is what's under the old slab and where the water goes when it runs off.
Send the form or call (425) 285-8618, and we'll reply within one business day to set a time. I come out to Maltby myself to look at the old concrete, the ground and the slope, and you get a free estimate with no obligation to book us.
(425) 285-8618Many of our Maltby calls are for long driveways and turnarounds, garage and shop slabs, and patios off the back of the house. Where the yard drops away from a door, we build concrete steps that sit on footings instead of loose fill, and where it drops harder, we build retaining walls. On older places we cut out slabs that have sunk or cracked and work out why before we pour the new one.
Snohomish County sets land use and zoning for Maltby, and its Planning and Development Services office issues building permits and clearing and grading permits in the county's unincorporated areas. When a county permit is needed, its review comes before the pour, so it sets the start date more than our calendar does. Washington requires every construction contractor to register with the Department of Labor & Industries and to be bonded and insured, so that's the first thing to ask anyone bidding your job. The county licenses only a short list of regulated businesses, and most contractors need no county license at all, but a job inside City of Snohomish limits needs that city's non-resident business license. Before we set a date, we find out which office covers your address and what your project calls for, then tell you plainly who'll handle the permit and the inspections.
The price moves with the size of the slab and what we find under it: how much old concrete comes out, how deep we dig to reach firm soil, how much rock goes back in and gets packed, how thick the slab needs to be, and how close the mixer truck can get. The schedule turns on the permit, if there is one, and on how long the new concrete has to cure, or harden, before it takes weight. You get your own number at the estimate, because I'd rather show you what you're paying for before we start than explain it after. We come up from Redmond for this work and do the same jobs across the cities around it, from Maltby down to Issaquah.
I come out for the estimate myself, walk the old slab and ask a lot of questions about where water runs and when the cracks showed up. Then our own crew does the work with me running the job, so the person who priced it is on site.
Nobody sees the dug-out, packed subgrade under a slab once it's poured, which is why it's the first thing a tight budget cuts. I'd rather trim the fancy finish than the base, because a pretty slab on soft ground still sinks.
We started with side jobs for neighbors in Redmond and have been in business since 2013, licensed and insured. Your satisfaction, guaranteed. To talk through your Maltby project, call (425) 285-8618 or send the form, and I'll come out to look.
Your price comes down mostly to the size of the driveway and the ground under it, so a long one on soft soil costs more than a short one on firm ground. Tearing out old concrete, digging down and packing a rock base, extra thickness and rebar, the steel laid inside to hold the slab together if it cracks, all add to it. A plain broom finish, the lightly brushed texture that keeps tires and shoes from slipping, costs less than stamped or decorative work, and I'll give you your own number at the estimate.
You're off it while the concrete cures, and walking on it comes well before driving on it. I give you both dates for your pour before we start, since a car on young concrete can crack or mark it. On a long driveway we can sometimes pour in sections so you're not shut out the whole time.
Most sinking starts underneath, when the base was raked flat instead of dug out and packed, so the slab settles as the dirt does. Water running toward or under the slab makes it worse, and cracks wander when control joints, the grooves cut so the slab cracks along a line we chose, go in late or not at all. Before we pour, I want to know which of those killed the old slab so the new one doesn't fail the same way.
We plan it from the ground up. After we reply, I come out, look at the old concrete, the slope and where the water runs, and work out what the slab or wall needs underneath. You know what you're paying for before we set a date.
You do if the slope on your parcel, or within 200 feet of the work, is 33 percent or steeper, because the county requires a geotechnical engineer to evaluate it. In a landslide hazard area the county allows building only when there's no other spot and its conditions are met, and a covenant that stays with the land, stating the hazard and that you accept the risk, has to be recorded before any permit is issued. A lot with no landslide on the state's maps can still have the hazard, so we look at the slope ourselves at the estimate.
A registered contractor has to give you the state's disclosure statement notice on any residential job of $1,000 or more. That's on top of the state registration covered above, so ask for the notice if nobody mentions it. From us you'll also get a clear estimate, so you know what you're paying for before we start.
