Metro concrete is a trip hazard repair company. We use many cost-effective repair methods to make sure that our customers are getting the biggest bang for their buck. Concrete grinding is used to eliminate trip hazard's that are smaller than 2 inches. Grinding is usually 10% the cost of replacement. Mud jacking or slab raising is used to raise sinking concrete instead of replacing it. Slab raising runs about half the cost of replacement. If neither grinding or mud jacking can repair someone's concrete then we will replace it but only when absolutely necessary. Concrete replacement is the most expensive method of repairing concrete.
