Hairline cracks on my driveway
I moved in a new house last year and my driveway was poured in May 2017. Today I noticed that there was a long hairline crack on the entire driveway (vertically) - almost 20 feet. It is very fine (1mm). I know crack on concrete is common but I was surprised that it happened now not at the time concrete was poured. Maybe extreme weather here in Saskatchewan caused this fine crack? Do you think it's just surface crack?
My question is, should I fix it in spring? or should I just leave it as is? If I need to fix it, what do I need to do?
