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.
5/16/16 Dave, It was about ten years ago that my basement walls started to move and leak. I called a local company to have the situation taken care of. They came over and proceeded to install a system that was meant to bring the walls back into position and prevent cracking and leaking. They did this by drilling through the walls and extending a rod out to the yard about eight to 13 feet from the house. It was supposed to be tightened to bring the wall back to the original place or close to it. It did move the walls ever so slightly, but return, cause more cracked in the walls. After repeated calls for the firm to come and fix the problems, the leaking did cease but the company asked me for $100 a year to guarantee their warranty. They worked on the East and South walls. Two years ago, the west and north walls began to leak and I called another local firm, because I lost all tryst in the first firm. They did the same procedure with the same results. Tighten the rods and get more cracking and more leaks. After continued leaking for the better part of the last two years, I decided, after a $15,000.00 expenditure, to call and get the basement fixed correctly to end the leaking. A competitor contractor mentioned your name and I called you. I had your firm mudjack my driveway a couple times, but I did not know you did basement work also. I accepted your bid in the winter of 2015 to do the work in the spring of 2016 and this past week, after two weeks, the job is complete! You excavated around the entire house, pushed back the walls, installed steel beams every four feet in the basement, filled all of the cracks inside and out and applied a sealer on the outside of the walls. I am confident that my basement is not sealed and should not leak. I can only have words of praise for the men who performed the work. They were not only courteous, but very hard working and when they left, the outside of my home was landscaped and the property cleaned up. We are very appreciative of the excellent quality of work you performed and look forward to a “dry” (SureDry) basement in the future! Again, Thank you Clyde Menasha, Wisconsin
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.
