Why Fix A Garage Slab?
Having to replace a section of sidewalk can be costly and inconvenient, but it is nothing compared with having to replace a compromised garage slab. In addition to the hefty price tag, homeowners have to remove everything from the garage for at least a week and must have their home accessible for excavation and repouring. While this process is sometimes necessary and is the best option in certain circumstances, concrete lifting should first be considered to save time, money, and hassle.
The two main causes of garage floor settlement are inadequate soil compaction/insufficient reinforcement by the original builders and soil shifting underneath the slab. With either of these initial causes the concrete slab is perfectly fine; it is merely a matter of the soil beneath the slab being compromised. Because of this, the process used to stabilize a garage floor slab by polyurethane foam lifting is the exact same as for sidewalk lifting or driveway lifting, just on a slightly larger scale. This in no way tests our capabilities; our foam systems are used for significantly bigger applications such as firetruck and bridge supporting slabs, man-made river support systems, and factory floor stabilization and reinforcement.

By strategically injecting expanding foam in a grid pattern throughout a garage, the compromised soil underneath can be reinforced to avoid future settlement and the garage slab lifted back up to its original position. Total work time for garage leveling projects is generally between 1-3 hours, and only minimal prep work on the homeowner is necessary. At most, removing cars and large items from the garage during the injection period is needed. When the crew is done, the only visual evidence of work having been performed are the penny-sized holes that are filled with a color-matching grout. The average price to fix a sunken garage is between $1,600-$3,200, with some projects being less expensive or more expensive depending on the amount of settlement and the size of the area requiring repair.
While garage lifting is a great option for garage settlement, it can not fix everything. Other common garage problems include excessive cracking and crumbling without any settlement. This is generally caused by poor concrete mix, erosion from salt brought in on car tires, and excessive temperature fluctuations. For these problems, the concrete will either have to be resurfaced if it is salvageable or otherwise replaced through demolition and repour.
