The good news is that a cracked concrete slab can be repaired in many cases. There are many different types of concrete crack repair kits. For cracks less than half an inch wide, there are several putty and sealant options available. Simply crush the crack and then use a trowel to spread the putty evenly.
A caulking option will dry quickly, in a couple of hours. Larhom An ugly and more extensive (expensive) repair involves removing the tiles over the crack, installing a mesh or membrane that isolates the cracks, and then putting them back on. But I would look at the entire building inside and out to determine the nature, scope and, in particular, the cause of the crack as if there was a meaningful agreement that needs to be addressed. Choosing the right product for the job is the first step.
If the repair is done between ¼ and 2 vertically, use the Sakrete quick-setting cement patcher. For repairs up to 4 vertical, approach the Sakrete Pro-Mix multi-purpose cement mix. Concrete surfaces cannot be repaired with concrete. Instead, use a concrete repair mix; these are available at home centers and online.
Options include epoxy compounds, latex patch material, and mortar mixes. The latter option works best for filling large cracks (or chipped edges), while the other products are suitable for cracks in concrete that are inch wide or narrower. The raised concrete was raised following exactly the path of the clogged and buried, frozen (and burst) drainage line. Settlement cracks in a concrete floor around a support Lally column can be indicative of a serious problem, such as building settlement if the columns are settling.
And I suspect that the concrete mix was wrong, maybe too much water, sand and gravel and little concrete. Crack cracks occur when the concrete surface dries and contracts at a different rate than the underlying concrete. A floating concrete slab is one that is poured with a (usually) uniform thickness on the ground without a separate base. Contractors should approach repairing plastic shrink cracks and drying shrinkage in the same way.
Some contractors repair concrete with more concrete, but this method only fills the crack and does not provide any tensile strength, only the bond strength, which is not strong enough to withstand typical movement. The use of carbon fiber reinforcement products has been proven to provide permanent solutions to a variety of cracks and damage in concrete, and offer contractors a permanent solution for concrete slab repair. While in some cases it takes a professional to work with concrete successfully, almost anyone can fix cracks in concrete. They do not compromise the structural integrity of the surrounding concrete and provide a permanent solution for slab crack control.
Often, cracks in slabs are repaired by epoxy injection or by filling the surface of the crack, and while this may seem to fix the problem, these repairs usually fail and result in callbacks or additional problems.
