I had a new concrete driveway installed in the spring of 2004 - house was completed in fall of 2003. I live in the Midwest and the winters can be pretty harsh with ice, snow and salt. The concrete was sealed by the contractor for an additional cost. In the landing pad area, the concrete is now pealing, flaking, crumbling and on certain corners is cracking. The front walk way, back walk way and patio are all fine. I am most likely way beyond any warranty, but am going to contact the contractor for advice. Is there anything I should or can be doing such as cleaning and resealing to prevent any further damage. Any advice on this annoying problem would be greatly appreciated.
