Concrete Slab Crack Repair
When a home inspector discovers a concrete slab crack, he or she may ask you about concrete slab crack repair options. These cracks can indicate a larger problem with your foundation, so you should have a professional look at the crack and determine what the best solution is. If you suspect a crack is caused by settling, you should contact a concrete repair company. Listed below are some tips to help you choose the right repair options for your home.
Stitching
While epoxy grout filling is a quick and easy option for fixing cracks in a concrete slab, stitching is a more structurally sound option. Stitching works by sewing two pieces of concrete together. To do this, a carbon fiber stitch is inserted from either side of the crack. The carbon fiber stitch will prevent the crack from expanding further. This method is particularly effective in cases where the slab is pulling apart.
One of the benefits of stitching is that it can be installed quickly and easily, even on damp substrates. This method provides additional reinforcement to the concrete and helps maintain the interlock of aggregates. It is commonly used in longitudinal joints to prevent slab separation. The technique is considered to be more reliable than traditional methods because of its ability to fix cracks without causing significant damage to the foundation. It can also be applied on cracked areas where the underlying slab is more fragile than the surrounding one.
Epoxy Injection
If you have a post tension foundation, epoxy injection is a better option. The post tension cables hold the slab together, but you need to fill the cracks to prevent moisture and insect intrusion. If moisture is allowed to seep in thru the cracks the post tension cables with rust and can snap under the pressure. This can damage the foundation and even the walls and tile flooring. It is also a much more expensive repair. To inject pressurized epoxy into the cracks to seal them and protect the cables.
