Concrete patio construction in Forest Lake MN - a slab that sheds rain and snowmelt
Old patio cracked, sinking or holding water? We pour a new slab on a packed base, sloped to drain, with joints we plan with you.
What goes into building a new concrete patio in Forest Lake?
Concrete patio construction in Forest Lake, MN means digging out the yard, packing a firm base and pouring a concrete slab sloped just enough for rain and snowmelt to run off, so you end up with a solid, even place to sit outside. Most of the work happens before and after the pour. Before it, we build the base underneath. After it comes curing, the wait while the concrete gains strength before you load it up.
Maybe the old slab out back has cracked and tipped toward the house, or water sits by the back door after every storm, or you've just got a patch of lawn you'd rather sit on than mow. The price moves with the size, whether there's old concrete to break out, how much digging and gravel the yard needs, the thickness and the finish you choose. The schedule turns on the weather and on what the city or the watershed district needs first, so before we set a date we check with the city and any other office the job touches. When I come out, I walk the yard with you and write down exactly what your price covers.
How our concrete patio construction works
I start by walking the yard with you and checking where water runs now, because a patio that tips toward the house sends every rain toward your foundation. We dig out the sod and soft dirt down to firm subgrade, the ground the slab sits on. Then we bring in gravel and pack it in layers, because a base that's only raked level settles with the dirt under it, and that's how patios sink and crack. We set the forms with a slight fall away from the house and lay rebar, steel bars that hold the slab together if it does crack. We pour early in the day, because concrete that sets in midday heat can end up with a weak, dusty top. We finish it with a broom, which leaves a light texture so wet feet don't slip, then cut the control joints, shallow grooves that give the slab a place to crack. We go over where those joints will sit with you before the pour, so any cracks land where we planned them instead of across the middle of your patio. If the budget gets tight, I'll tell you to cut back on the finish before the base, because nobody sees the base on day one, but you can't fix it once the slab is on top.
A lot of patios tie into other work. If you'd like a pattern and color pressed into the surface instead of a broom finish, that's our stamped concrete services, and the slab still sits on the same packed base. If you need a path from the driveway or side door, our concrete sidewalk building can go in during the same job, so the forms and the slope line up.
Why Forest Lake homeowners call us for a concrete patio
The owner estimates and pours
I come out to look at your yard and write the estimate, then I work on the crew that builds it, so the person who agreed on the slope with you is there setting the forms. I started Forest Lake Concrete in 2023 after learning the trade on a local crew.
An estimate that lists the work
I write down what the price covers, from tear-out and base to thickness and finish, so you can compare it line by line with anyone else's. I'd rather spend an extra half hour on your questions than have you guessing after we leave.
Licensed and insured, worth asking about
Minnesota requires a residential building contractor or remodeler license when someone you hire directly takes on work at a house with up to four units and the job covers more than one special skill, and digging and concrete count as separate skills. We're fully licensed and insured. Ask any contractor, us included, which skills your contract covers and who's doing the digging, since the City of Forest Lake requires excavators to hold a city license.
Watershed rules planned for up front
We're based in Forest Lake and work across the cities around it, and every site inside the watershed district, CLFLWD, has to put in erosion control like silt fence or biologs, which are rolled fiber logs, while the dirt is open, whether or not a permit is needed. If your patio needs a permit, we help you sort it out and tell you who we've talked to.
The base and the slope matter more than anything on top, so ask any contractor about those first. When you're ready, send us your patio details or call (612) 448-0764 with the size you're picturing, what will sit on it and whether your lot is near a lake or wetland.
Get a written estimate for your new patio
Tell us the size you're picturing, what the patio will hold and whether your lot is near a lake or wetland. We reply within one business day to set a time, then I come out, walk the yard with you and write down what your price covers. The estimate is free, and there's no obligation.
Patio slabs and finishes
Questions before you build a concrete patio
How much does a concrete patio cost in Forest Lake?
A concrete patio's price comes from its size, how much old concrete or dirt has to come out, how much gravel the base needs, the thickness and the finish. A plain broom finish costs less than stamped or colored concrete, and a tight backyard where equipment can't get close adds labor. I'll walk your yard and write down what your price covers before you decide anything.
How thick should a concrete patio be?
Most patios are about 4 inches thick, the same as a typical sidewalk, while flatwork that carries heavier loads is often 6 inches. If you're planning a hot tub or anything else heavy, ask each contractor whether 4 or 6 inches fits your plans, and we'll ask you the same thing at the estimate.
What causes a new concrete patio to crack?
Concrete shrinks as it dries and moves as temperatures change, so most slabs crack somewhere, and joints decide where it cracks, not whether. Plan for some cracking and ask any contractor how the joints will be laid out across your patio, which is why we settle that with you before the pour.
Can I pour a concrete patio in October in Minnesota?
You can, but a patio poured in October or November needs extra care, because a Michigan concrete group's guidance says late-season concrete may not get enough drying time before deicers go on. The same group suggests skipping deicers until the patio is a year old and using sand for traction on snow and ice. It also says new concrete in cold weather should stay under insulated blankets, above freezing, for at least 3 days until it's strong enough to use.
What permits do I need to grade my yard for a patio in Forest Lake?
The watershed district requires a permit when grading or filling moves 50 cubic yards of earth or more, and the city helps residents get the permits they need. Lake and wetland lots have more triggers, including any wetland impact, grading in public waters or within 40 feet of the bluff line, and disturbing more than 100 square feet where a shoreland setback variance is needed. Questions about setbacks or how big you can build go to the city's Zoning Department.
How do I take care of a new concrete patio?
Plan on resealing about every three to five years, since that's how often most concrete sealers need a fresh coat. To check, sprinkle some water on the patio, and when it stops beading up, it's time to reseal.
Other concrete work that goes with a patio
- Stamped concrete services
If you'd rather the patio look like stone or brick than plain gray, stamped concrete presses a pattern and color into the slab while it's still fresh.
- Concrete sidewalk building
A new walk from the driveway or side door gives you a dry, level way to the patio instead of a muddy path worn across the lawn.
