Lynn M. of Sherwood, AR called about an area of her walkway that was a trip hazard. Her concrete was sinking. We also discovered that her driveway was suffering from the same issues. We used our PolyLevel™ Concrete Injection System to lift and level her walkway. We sealed the joints with NexusPro™ sealant. This will divert water away from the walkway, keeping it from causing further damage.
