Hi,
Seeking advice on how to tackle repairing portion of concrete floor of garage.
Small portions of the slab closest to the garage door opening are exposed so that you can "sweep" out the dust and small pieces of gravel that made up the concrete. It is all within 8-10 inches of the slab end (where it meets the asphalt driveway). The flaking (or whatever it is called) is only about 1/2" deep at the deepest point and does not present a structural problem. This, as far as I'm concerned, is strictly an aesthetic issue (in addition to always having to sweep up tiny amounts of dust/concrete pebbles).
What are possible solutions? For ex., is there a way for me to either cut (with a saw?) a few inches (how much is enough, too much?) off the top of the affected areas and repair (with what material?). Maybe just chip away the affected area with a chisel to get down to a recommended depth (what is it?) and then use some kind of re-surfacing product or fill-in product? Obviously, whatever material I use must bond to the existing slab, so that appears to be where I would struggle with the right solution.
Thanks,
Al

PARTNER SAWS - By Fire Hooks Unlimited (http://www.firehooksunlimited.net/saws.html)
I would cut a line behind that 10" you mentioned with a partner saw. See link. Chop out the loose pieces at least 3 inches down, if not all the way. Then mix some portland cement (3 sand to 2 portland) & fill the gap.
