i hired dave mallozzi in warrington pa to give me a concrete driveway. he said that i would get 6 inches of concrete 6 inches of crushed stone and reinforcement wire. i later found out through a core sample that there was less than 6 inches of concrete no stone added and no reinforcement wire. he damaged the walls of my garage. there are no expansion joints and the job looks very sloppy. beware of this contractor. the driveway was installed on november 2009 in one day. i later found out through other contractor that this is a two day job. a section of the driveway had heaved in the cold and buckled the siding of my garage.
