Re: concrete driveway repai
I have fixed many cracks, and your best option for a few years is forget the caulk and the sealant. THEY ARE CRAP!!!
You are from the burgh, I am sure you are familiar with the steel building, I have fixed many cracks on the steel plaza. You want to get a masonry wheel for either a grinder or circular saw, and cut the concrete back to where you have 8" to a foot to fill, then chip that out with a chipping hammer. you can rent them fairly cheap at HD. leave some rough edges on either side, and paint with a concrete boding agent (follow directions on bottle). cut some mesh to fit in the hole, and pour concrete into said hole. make sure you shopvac the hole before you paint
you dont have to make a million, just be thankful to be workin'
