Concrete Driveway Crack Repair?
Question:
I’m not a driveway or concrete guy but if freezing is a concern, it should be sealed when it is cold. If you do it in the summer, when it cools it will contract and pull away from the seal. I would suggest a flexible sealer or tar (I know it’s ugly but you could do the entire drive to match?) Ever notice when the highway crew fills the cracks with tar? Instead of doing it in the summer when it would flow nice in the heat, they do it near winter when the cracks are getting large and just before there is any chance of a deep freeze. — Tony – Hide quoted text — Show quoted text – > Dave, I was sorta thinking the same thing, but a guy emailed me that if water gets into the crack > and freezes, it will expand and force the crack even wider.

If you are in the 4 season area,you can expect this type of condition. Winter ground movement. Ground expands when frozen and contracts in the spring. Best bet seal with concrete caulking seal now to prevent water and ice from causing more damage now.Spring time repeat procedure. Because of ground movement,expect it to be a on going seasonal thing. http://community.webtv.net/MasonRepairs202/MasonRepairs

Some thoughts/questions on your driveway: The horizontal cracks that were put in are actually to give a place for a crack to "happen" as opposed to a random crack. Then, if reinforcing wire/rod was used, the crack should pose no significant problem. All comments about sealing to prevent water getting under the slab are relevant. I’v used some of the concrete caulk mentioned, and it doesn’t look too bad as long as it’s not smeared. Ace – Hide quoted text — Show quoted text – > My concrete driveway was put in about a year ago.

Dave, I was sorta thinking the same thing, but a guy emailed me that if water gets into the crack and freezes, it will expand and force the crack even wider. I really have no clue.

IMHO an unpatched crack is always less noticable than one that’s been repaired. (at least for hairline cracks) – Hide quoted text — Show quoted text ->How should I fill the crack?

My concrete driveway was put in about a year ago. It is cracking. The company that installed it said "some cracking is normal". Both cracks go right through the horizontal lines in the driveway that I thought were supposed to stop a crack from propagating. The driveway is 75 feet long and the larger crack runs for about 50 feet — width is 1/16 to 1/4 inch. Questions: Should I wait for the crack to stop growing before I patch it? If I patch it and then have to later patch it again, that could look ugly. How should I fill the crack? The Home Depot and Lowes stores have a paste that comes in a tube (silicone based goo). Is this the best way to go? It’s cold here now (North Carolina, USA). Should I wait until spring? Alan -if this were a binary group, I could post images of the cracks taken with the digital camera
