A sunken slab is a trip hazard and a drainage problem waiting to get worse. We lift it back to level in a few hours - no jackhammers, no weeks of waiting, no concrete hauled away.
Foundation raising in Fond du Lac is the process of pumping material beneath a sunken concrete slab to fill the void underneath and push the slab back to its original level position - most residential jobs take two to four hours, and you can walk on the repaired surface the same day.
If you have a sidewalk panel that has dropped, a garage floor that slopes where it used to be flat, or a front stoop that has settled away from the house, foundation raising is almost always less expensive and less disruptive than tearing out the old concrete and starting over. Fond du Lac homeowners deal with this every spring - the ground freezes hard every winter and thaws every spring, and that cycle gradually creates voids beneath slabs. It is not a sign that anything was done wrong with your home. It is simply what happens to concrete in Wisconsin over time. If you have a slab that has also cracked and needs a new pour rather than lifting, our concrete cutting service can remove damaged sections cleanly before replacement work begins.
The process works best when the concrete itself is still in reasonable shape and the problem is the void or soft soil underneath - not the slab surface. A quick site visit tells you which situation you are in before you spend any money.
If you can feel a lip or bump when you walk from one concrete panel to the next, that is a classic sign of settling. In Fond du Lac, this often becomes obvious in April or May after the frost leaves the ground. That uneven edge is also a trip hazard - if someone falls on your property, you can be held responsible.
When a concrete slab settles, it can tilt toward the house instead of away from it. That means rainwater runs toward your foundation instead of draining away. In a city with Fond du Lac's soil moisture levels and proximity to Lake Winnebago, water sitting against your foundation is a serious concern that can work its way into your basement over time.
Garage floors are one of the most common places for settling to show up, especially in older Fond du Lac homes where the garage slab was poured separately from the foundation. If your garage floor feels uneven underfoot, or if a crack running across the floor has widened over the past year or two, the slab may be sinking.
A basement floor that was once flat but now has a noticeable dip or a crack that has opened up is worth having assessed. In homes near the lake or in low-lying parts of Fond du Lac, soil movement from moisture changes is a common cause. This is not always an emergency, but catching it early keeps your repair options open.
We raise sunken concrete slabs throughout the Fond du Lac area using both mudjacking and polyurethane foam injection, depending on which method suits the slab, its location, and the homeowner's budget. Mudjacking uses a cement-and-soil slurry pumped under the concrete to fill voids and push the slab back up - it has a long track record in Wisconsin's climate and tends to cost less than foam. Foam injection uses a lightweight expanding material that cures faster and puts less weight on the soil, which makes it a good choice for slabs close to a home's foundation wall. For homeowners whose slabs have shifted significantly or require new concrete rather than lifting, we coordinate with our slab foundation building service so the whole scope of work gets handled under one roof.
Beyond driveways and garage floors, we also raise front stoops, back patio slabs, sidewalk panels, and pool deck sections. Every job starts with a free on-site estimate. We walk the area with you, explain what caused the settling, tell you whether raising is the right fix or whether something else is needed, and give you a written price before any drilling begins. If you are also dealing with concrete that has settled so badly it needs to be cut out and replaced, our concrete cutting team handles that work cleanly so the replacement pour starts on a solid base.
Best for homeowners who want a proven, cost-effective method for lifting driveways, sidewalks, and garage floors with a long track record in Wisconsin's freeze-thaw climate.
Suited for slabs near the foundation wall or in tight spaces where a lighter material, faster cure time, and minimal disruption matter most.
Ideal for a sunken front stoop or entry slab that has created a trip hazard at the door - typically completed in two to three hours with same-day results.
For outdoor entertainment slabs that have settled unevenly, creating low spots that collect water or make the surface uncomfortable to use.
Fond du Lac sits at the southern tip of Lake Winnebago, and the combination of a cold northern Wisconsin climate and soil that holds significant moisture makes settled concrete a near-universal experience for local homeowners. The ground freezes hard every winter and thaws every spring - that repeated cycle pushes soil up and down year after year, which gradually creates the voids beneath slabs that lead to settling. A significant portion of Fond du Lac's residential neighborhoods were built in the mid-20th century, meaning many homes have concrete that has been through 40 to 70 years of those cycles. If your home was built before 1980, checking your sidewalks, garage floor, and front stoop every spring is a smart habit. Homeowners in Oshkosh and Neenah deal with the same freeze-thaw conditions and often call us for the same reason.
The clay-heavy soils common near the lake expand when wet and shrink when dry, which puts additional stress on slabs even in areas that were properly graded when the home was built. That soil movement is one reason why voids form beneath slabs that appear fine from the surface. Scheduling a foundation raising job in early spring - before the ground softens further after winter - is smart for two reasons: it stops the slab from settling further, and it means you are calling before every other homeowner in town does the same thing when the snow melts. Spring is the busiest season for this work, and wait times grow as the season progresses. You can learn more about Wisconsin's freeze-thaw climate zone from the USDA Plant Hardiness Zone resources, which document why this region experiences the soil movement patterns that affect concrete over time.
When you call, we will ask a few basic questions - which slabs are affected, roughly how much they have settled, and whether there are any visible cracks. This helps us show up with the right equipment. Most calls take 10 to 15 minutes, and we aim to return messages within 1 business day.
We walk the area with you, check how much the slab has dropped, and look for signs of what caused the void underneath. We tell you honestly whether raising is the right fix or whether the slab is too far gone to save. You leave with a written price - no obligation to move forward.
Before the crew arrives, move vehicles out of the garage or driveway, pull patio furniture off the affected slab, and make sure the crew can get their equipment close to the concrete. We will tell you exactly what to move. This usually takes less than 30 minutes on your end.
The crew drills small holes through the concrete, pumps the lifting material underneath, and watches the slab rise gradually. Once level, they patch the holes and clean up. For most residential jobs this takes two to four hours. Before leaving, we walk the finished area with you and tell you exactly when the surface is safe to use again.
Free on-site estimate. Written price before any drilling. Most jobs done the same day.
(920) 375-8490We give you a fixed written estimate after the site visit - not a range, not a ballpark. You know exactly what you are paying before the crew arrives. In a market where low estimates and rising invoices are a common complaint, that written number is your protection.
Foundation raising in Wisconsin is not the same as doing it in a milder climate. We know how spring timing, soil moisture near Lake Winnebago, and freeze-thaw cycles affect both the settling and the repair. That local experience changes how we approach each job and what we recommend after the work is done.
Most front stoops, garage floor sections, and sidewalk panels are level and ready for foot traffic the same day the crew arrives. You are not waiting for a pour to cure or a dumpster pickup to happen before you can use your driveway again. The crew arrives, does the work, patches the holes, and cleans up.
Some slabs are too far gone to raise - and a contractor who tells you otherwise is one you should not hire. If replacement is the better answer for your situation, we will tell you that before you spend money on lifting. The American Concrete Institute sets the standards our work is measured against, and we follow those guidelines on every job.
Every one of these points comes back to the same thing: a contractor you can trust to give you a straight answer. That is what we try to be every time a Fond du Lac homeowner calls us about a settled slab.
When a slab is too far gone to raise, we cut it out cleanly so a replacement pour starts on solid ground.
