A cracked concrete slab can be caused by concrete shrinkage or changes in the soil underneath. Because of this, simply repairing with epoxies will not prevent an active, moving crack from opening up again. Luckily, Moisture Loc has a permanent solution using our Concrete Crack Loc System. This system prevents slab movement from the inside of your foundation, without the need for excavation. Contact us today for a free consultation. Serving Charlotte NC and the surrounding areas.
