Wide cracks in concrete are better patched and sealed with a concrete patching compound. Patching compounds are usually mixed with water and applied with a trowel. For deeper cracks, we recommend using an epoxy sealant. An epoxy sealant can also be used in smaller cracks, but for larger fractures in concrete, you will want to stick exclusively with an epoxy remedy.
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. 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 good news is that Edens Structural Solutions is Tulsa's trusted concrete foundation expert, with over 34 years of experience protecting homes and giving you peace of mind. The crack will meander along the concrete, narrow to a stop, and then continue to start on a line parallel to the first crack, meandering through the concrete again.
Conversely, a concrete slab may have settled on a poorly compacted or washed backfill (as in some garages) without cracking (instead, tipping over), but it may be necessary to repair it to correct the slope, provide drainage, or prevent further settlement or even collapse. The same standard states that cracks that occur in the control joints of concrete slabs are normal and acceptable. We discuss the recognition and importance of shrinkage cracks in concrete in detail in Shrinkage Cracks in Slabs. You can see the shrinkage of even a perfect concrete slab without visible cracks in the field of its surface if the floor is poured inside an existing base.
I am certainly guilty of letting concrete problems persist until a larger and more costly solution is required. NYC You'll want to cut or grind the top of the unused rebar bump to below the concrete surface, then seal the surface with a weather resistant concrete surface patch. The area should be thoroughly pressure-washed to remove all dirt, chemical residues and loose concrete from the surface of the slab. Slab repairs are often overlooked and contractors may even avoid talking about slab cracks due to lack of permanent solutions.
We decided to go into the concrete repair business because it is a less competitive business and there is a lot of work. Concrete contractors are often asked to address non-structural imperfections that can occur soon after a concrete slab is laid. 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.
