Concrete Floor Cracks
Cracks in concrete floors happen for a number of reasons, like subgrade settlement, premature slab dryout, curled slab, bad control joint design or heavy load use. Concrete crack repair for commercial and industrial applications is complicated and needs to be assessed properly. Otherwise the work will be short lived, and the building owner will have to stop work again, and address the concrete crack issue.
It’s important to determine which of these problems may have caused your concrete to crack. If you repair cracks in a concrete floor that are experiencing any movement it may lead to your repair failing prematurely.
Assuming the cracks are stable, we would repair a crack using the following methods.
Fixing Cracks in Concrete Floors
If your cracks are not stable (meaning they move up and down when you drive over them with a load) you will need to stabilize the cracks prior to repairing them. To determine if your cracks are moving stand with one foot spanning both sides of the crack and drive a heavy load over the crack and see if you feel any movement. You should not feel any movement at all. If your crack is moving it is very important to stabilize the crack movement before any repair.
This process is know as slab stabilization and can be complicated and technical. ICS repairs miles of cracks every year and has the knowledge, equipment and techniques to perform crack repair right the first time.
