Uneven concrete slabs can present safety issues, damage vehicle tires, and look unappealing. For over 40 years we have been helping homeowners throughout Wisconsin avoid the expensive option of concrete replacement by raising and leveling their concrete instead. You can resume normal use of your surface within minutes of leveling, and depending on the size and accessibility of the work, most projects take no longer than an hour from start to finish.
In Wisconsin especially, it’s no secret that cold, wet winters can wreak havoc on your concrete. With the ongoing expansion and contraction caused by the changing weather, the ground below your driveway, sidewalks, and surrounding your foundation will—over time—begin to shift. If you have a concrete slab in your driveway, sidewalk or basement which is uneven, or even cracking, replacement of that slab is not your only option.
What types of problems can concrete raising fix?
Concrete raising is a fantastic alternative to replacing your concrete, often times saving you over 50% of the cost of replacement! Some common areas we raise, level and repair concrete slabs are patios, front porches, driveways, sidewalks, garage & parking slabs, steps, and pool decks.
I recently purchased a home that had a bowed wall. I called RaiseRite and they sent out an expert in that field to diagnose the problem and estimate the cost to straighten the wall. They also recommended having the exterior of the wall sprayed with high density polyurethane. The polyurethane will act as a crack sealer, water sealant, and excellent insulating characteristics. My job was completed in three days and didn’t affect my home life. The wall was restored to its original condition and put value back into my home. The crew was extremely professional and did an excellent job of cleaning up. Thanks RaiseRite! ~Dave Manitowoc, WI
Concrete raising in Wisconsin is the first option you should explore when considering fixing your uneven concrete slabs. There are two main types of concrete raising solutions available—polyurethane foam concrete raising and mudjacking concrete raising.
What causes concrete to settle?
Poor or improper compaction of the base before concrete was poured: The weight of the slab will further compact the base after curing, and settlement can happen quickly.
Climate: The Polar Vortex, experienced last year by many in the northern hemisphere, wasn’t just hard on you, but also on your concrete. Freezing and thawing causes slabs to expand when frost is in the ground – it causes concrete to heave or raise. When the ground thaws, the concrete will settle again, but many times not to where it was originally. This results in trip spots between shifting slabs. On the opposite end of the climate spectrum, heat and drought can cause expansive clay soils to shrink, causing the slabs to settle. When the clay soils receive rain, and expand once again, the concrete slabs shift and become uneven.
Erosion: Damaged water and sewer lines, improperly placed downspouts and excessive rain can all lead to a washout of base materials under concrete causing the slabs to settle.
Machine/Traffic Vibrations: Concrete slabs may shift or settle on highways or in industrial settings where there is frequent heavy vibrations or loads being transported. The vibrations from machinery and passing traffic can lead to the base compacting and slabs settling or moving.
Slab Curl/Rocking Slabs: Slab curl occurs when a relatively large section of concrete is poured. During the curing process, the top slab may cure slightly faster causing the slab to curl, rock, and become unstable. Vibration can also cause slabs to settle.
