Building on a new lot and unsure which foundation fits? We'll match it to your slope and drainage and build it to handle frost.
Foundation installation in Aberdeen means building the concrete base your house sits on, built so freezing ground can't push it around, and it all happens before the walls go up.
If you've got a lot and plans, the first thing to settle is which foundation fits the ground. Our ground freezes, so the foundation has to resist frost heave, which is soil lifting as it freezes. One way is a T-shaped slab on deep concrete footings. The other is a frost protected shallow foundation, where insulation keeps the soil around the house warmer, and national guidance says that lets it sit shallow in almost all of the continental US.
The method moves the price and the schedule more than anything, because a T-shaped slab with deep footings is more complex, so it takes longer and costs more than the shallow kind. On a slab, every plumbing drain goes in, in the right order, before any concrete, since fixing or adding one after the pour is hard and expensive. When the job needs a permit, we take care of the application and keep you posted. Your estimate lays out what's included for your lot.
You reach me at (605) 824-9815 or through the form, and I get back to you to set a time to come out. Tell me a little about the lot and what you're building so I know what to look for.
I come out myself, and we look at your slope and where the water runs to settle on the foundation that fits. Have your house plan handy so we can talk through the drain layout right there.
Your estimate spells out what's included, from the method to the prep under the concrete. I'm happy to go through it line by line so nothing about the price catches you off guard.
Once you say go, we handle any permit paperwork, set a pour date that works with the weather, and the city inspects the work against minimum code standards along the way. I'm on site with our crew from prep through the finish.
Much of the ground around Aberdeen is mapped as the Aberdeen soil series, very deep and moderately well drained, formed in old glacial lake sediment, and water moves slowly through its top layers. That's a soil map, not your lot, but slow-draining ground is why water gets planned with the foundation. Slab guidance starts with grading the site to shed water, then gutters and downspouts sized to carry it off, and a vapor retarder over a gravel capillary break, a layer that stops ground moisture wicking up.
Before anything gets staked out, the house has to meet the city's setbacks from your property lines, and you can call Aberdeen's Community Development Department at 605-626-7017 to find the ones for your zoning area. For projects under the county's jurisdiction, Brown County Planning and Zoning reviews building and floodplain permits. We're based in Aberdeen and work in the cities around it, on houses and on business jobs like a shop slab or a concrete parking lot.
What a foundation job covers:
Most foundation installs are new work, a house or an addition going onto open ground, so the real choice there is the method. If an existing house has settled, a new foundation isn't always the answer, and foundation raising can be worth a look first. Once I've seen the cracks, the grade and where the water goes, I'll tell you plainly which way I'd go and why.
Past the method we covered up top, it's mostly your lot. How much grading it takes, how many drains go in under the slab, and whether the soil calls for drain tile all add work. The base under the concrete is where people usually want to save first, and it's the one place I won't cut, because nobody sees it on day one but a nice top can't save a bad base.
I learned this trade from an old-school contractor who made me reset forms until they were dead straight and wouldn't let a truck pour on a base he hadn't walked himself. I started Aberdeen Concrete Company in 2023 to run jobs the same careful way, so I walk the base myself before we pour.
I also want you to understand your job before we start, so the plan and the price don't catch you off guard. We treat your yard like it's ours, keep the site tidy while we work and clean up before we leave. Satisfaction guaranteed.
Call (605) 824-9815 while your house plans are still on paper, since that's the easiest time to settle the foundation and drains.
Put in your lot address, whether it's inside city limits and where the plumbing drains will go. I'll reply within one business day to set up a free on-site estimate, with no obligation.
On steep or uneven ground, a T-shaped slab with deep footings is usually the better choice, because it relies on footing depth to resist frost heave. The shallow insulated kind tends to suit flatter lots, and I'll look at your grade with you before we pick.
Your cost comes from an on-site estimate, because it turns on the method, your lot and how much water work it needs. I write out what's included and walk you through it, so call (605) 824-9815 to set up a visit.
Check with the city's Building Inspection Department, which issues building permits for residential construction, because foundations aren't on its list of work that needs no permit. That list covers things like painting and short retaining walls, and if your job needs a permit, we'll handle it.
A contractor doing residential work in Aberdeen has to be licensed through the City of Aberdeen, whether they're based in the city, elsewhere in South Dakota or out of state. We're licensed and fully insured, so ask anyone you're comparing whether they hold that city license.
Watch for water and moisture around the house, keep the drainage working and landscape so water runs away from the slab. With a frost protected shallow foundation, also keep the inside warm enough through the cold months, since that warmth helps keep frost out of the ground underneath.
The soil traits that matter most are depth, slope, erosion, runoff, shrink-swell potential, water table and flooding. Shrink-swell means soil that swells when it's wet and shrinks when it dries, and when I come out, I'll tell you how each one applies to your lot.
