Pictures don't really show it. Salt will cause spalling, in fact many people do a rock salt finish. Where did the salt come from?Hello all. New to this website. Need some opinions expertise. New driveway and live in Michigan. Experiencing a lot of flaking after 1 month of install. It was installed last November and it did rain that day. Builder is claiming salt caused it and we are still trying to get if fixed. Possibly the issue but could it of been a bad mix, not a winter mix or the rain when it was being laid. It was not covered during the rain. Also step on front porch cracking and porch cracking. It’s been 1 yr for all. Thank you
Doesn't look like your porch cracked. That's just the seam of where they poured against. Your concrete shrunk a little (normal) and I guess you think it cracked.
Perhaps you can get that caulked if it bothers you.
