What goes into building a concrete parking lot in Redmond?
Concrete parking lot building in Redmond means removing the old surface, packing a firm base and pouring a concrete slab that handles daily parking with less upkeep than asphalt. Most of the time goes into prep and curing, not the pour itself.
Usually the call is about a gravel lot that ruts out every winter or old paving that's cracked and holding water. The price moves with the size of the lot, how much old surface has to come out, how much base work the ground needs and how the water will leave the lot. The schedule turns on the city's review, the weather and the days the slab has to cure before anyone parks on it. If old paving has to come out in clean sections, that's a job for concrete cutting. Either way, I'll give you a written quote with each part on its own line, so you can see where the money goes.
How do you know your parking lot needs replacing?
Ruts and mud in gravel
Every wet season the gravel pushes into ruts, puddles sit in the low spots and mud tracks into the building. That usually means the base was never built for traffic, and each year of regrading is money spent on a surface you'll still have to replace.
Cracks spreading through old paving
One crack turns into a web, and pieces start to loosen where cars turn and brake. It usually means water is getting under the surface and softening what's below, and the longer it sits, the more base we have to dig out and rebuild.
Water standing after rain
Puddles that hang around for a day or run toward the door mean the slope is wrong or the base has settled. Standing water keeps soaking the ground under the lot and makes a slick spot for anyone walking in, so it tends to get worse, not better.
How we build a concrete parking lot
A lot is a business decision as much as a concrete one, so I start by helping you weigh what it costs now against how long you plan to use it, and we talk early about where people will park while it's closed. Then our crew digs out the old surface down to firm ground and packs the subgrade, the ground the slab sits on, because a base that's only raked level settles with the dirt under it. We set the grade so water runs off the lot and away from the building, set the slab thickness for the heaviest vehicle that will use it, and lay rebar, the steel that holds the slab together if it cracks. We pour in the cooler part of the day so the top doesn't come out weak and dusty, give it a broom finish so tires and shoes grip in the rain, and cut control joints, shallow cuts that tell the slab where to crack, while the concrete is still young so the cracks land where we chose. The base is the part nobody sees on day one and the first thing people want to cut from a budget. I'd rather spend your money there and keep the finish plain, because you can't fix bad prep once the truck has left.
Lots rarely come alone. Light poles, sign posts and bollards sit on concrete footings, and we pour those with the lot so they're on the same schedule. If a building next to the lot has settled and its doors or walkways no longer line up, foundation raising is worth looking at before we set the lot's grade to meet it.

What happens after you call us about a parking lot in Redmond?
Here's how a lot goes from your first call to the day you open it again, and who you'll deal with at each step.
Call or send the form
Call (425) 285-8289 or send the form, and we'll get back to you to set a visit. Have the lot's rough square footage, what's on it now and your target dates handy.
I walk and measure the lot
I look at the site, measure it and ask how you'll use it, from cars to delivery trucks. You get a written quote with each part of the job on its own line, so nothing hides in one total.
We set dates and permits
Once you say go, we set a date and take care of the permit side if the job needs one. The city says its clearing and grading review generally takes 4 to 5 weeks, so that wait goes ahead of the start date.
We build it, I run it
Our crew does the work and I'm on site running it from the prep to the cleanup. The lot stays closed while the slab cures, with the parking plan we talked through at the start.
Why Redmond owners call Allied Redmond Concrete for parking lots
On a lot, the base and the drainage decide whether it's still flat after many winters, so that's where I spend the most time on your quote. Get in touch and I'll come walk it.
I quote it and run it
I come out to look at the lot myself, and I'm on site running our crew while they do the work. The person who priced your base is the one checking it before the pour.
Flatwork and foundation crews first
I learned concrete on flatwork crews, the ones that pour flat slabs like driveways and lots, and on foundation crews before starting this business in 2021. That's where I saw what a skipped base costs a few winters later.
Licensed and insured, and checkable
We're licensed and insured. Washington's Labor & Industries Verify tool shows whether any contractor you're comparing has an active registration and paid-up workers' comp for its crew, along with any safety violations.
Ask us where trucks wash out
Redmond's stormwater rules keep concrete truck washout off the ground and out of storm drains, streets and streams, so it happens off-site or in a set washout area. It's a fair question for every bidder, and we'll answer it at the estimate.
Permits, rain and runoff on Redmond parking lot jobs
The City of Redmond requires a permit and approved plans once a project creates or replaces 2,000 square feet or more of hard surface, and most parking lots get there. Paving a dirt or gravel lot counts as new hard surface, tearing old paving out down to the base layer underneath counts as replaced surface, and pervious concrete still counts, so it won't get you around the rule. Once a project crosses the city's thresholds, its stormwater rules apply too. If your lot needs a permit, I tell you at the estimate and we handle the application and inspection requests, and if a question falls outside that, I'll point you to the right permit office.
Rain is the other local factor. Any work expected between October 1st and April 30th needs a city-approved wet weather plan for erosion and sediment control, so a fall or winter start needs time for that plan. We're based in Redmond and work in the cities around it, and the wet winters are the same on jobs in Kirkland and Woodinville, so we keep a dug-out base protected from rain until the concrete goes down.
Questions about concrete parking lots in Redmond
(425) 285-8289How much does a concrete parking lot cost in Redmond?
Building a concrete parking lot across the US usually costs about $5 to $10 per square foot for the finished lot. That's a national guide price, not ours. Your number in Redmond depends on the base work, the drainage and what has to come out first, and our written quote shows each of those on its own line.
Is a concrete parking lot worth it over asphalt?
It is if you plan to keep the lot a long time. Asphalt typically costs 20 to 40 percent less up front, but concrete lasts about 25 to 40 years against 15 to 25 for asphalt, and over 30 or more years concrete often matches or beats asphalt on total cost. If you're likely to sell or rebuild in a few years, asphalt's lower price can make more sense.
How long does it take to build a concrete parking lot?
Installing a parking lot usually takes 2 to 4 weeks, depending on its size, how many features it has and the site. Material shortages or bad weather can slow it down, so leave some slack around your business, and count the city review on top of that before the start date.
How soon can we park on a new concrete parking lot?
Plan on at least 7 days before cars go back on it. That's curing, the wait while concrete gains strength, and the slab reaches full strength at 28 days. Keep the lot closed or line up other parking for at least that first week.
How often do concrete parking lot joints need resealing?
It depends on the sealant, from 3 to 8 years for hot-poured, 8 to 10 years for silicone and up to 20 years for preformed seals. Preformed costs the most and hot-poured the least, so you're trading the upfront price against how often you'll reseal.
What causes a concrete parking lot to crack and sink?
Usually a soft or poorly packed base, water getting under the slab, and control joints cut late or skipped. Concrete still cracks some, so the aim is a base that doesn't move and joints that keep cracks in straight lines. That's the prep work described above, and it gets its own line in our quote.

Concrete footings
Light poles, sign posts, bollards and small sheds next to a lot all need a solid footing below them, sized and set before the slab goes in.
Foundation raising
When a building beside your lot has settled and its doors, steps or walkways sit low, lifting it back first lets the new paving meet it cleanly.
