Hey guys, my house is around 6 months old and we have notices that our driveway is heaving about 1" above our garage floor (concrete breaking underneath brick work). The brick work is also pushing up against siding causing this to buckle. I have went around to a couple of the neihbors houses and thier driveways are not like this. Will the slab return to normal? Is this a warranty issue with the contractor? Thanks for any info.
