Hello to all. I have posted to this group a few times and have received excellent advice.
A few weeks ago, I posted a question about concrete repair. No responses were given. Perhaps it was overlooked, as there were many other postings. Or, no offense, simply no one chose to respond.
My question is, is it ok to repost a legitimate repair question in this group?
Okay, I'll play- to answer your original question, I'd try to pull out the old pieces and refill with new material. Dig out as much loose material as you can, and try to dig down to solid sub-surface material. If all you see under it is dirt, put a layer of sand or gravel in bottom. Corners break off when substrate washes out or compresses, and it either gets full of water and freezes, or a car drives over an unsupported edge. Projects like this is what SakCrete and similar premix products are for. Mix it up pretty stiff in a bucket or washtub, cram it in there, and screed it off. As soon as it starts to set a little, use a broom to put lines in it to match the rest of driveway. If you are worried about a color match, you can mix in a fistfull of tint from the tile grout aisle. Otherwise, Mother Nature will make it match in a year or three.
Hey, you have pretty much nothing to lose but an hour's work- SakCrete is cheap. If it works, it works, if not, no big loss. And it will be a lot cheaper than epoxy. It may work well enough to tide you over until city repaves street, replaces curbs, and gives everyone a new matching driveway entrance.
