Concrete walk way (L shape concrete plate, from one side of drive way to front door concrete stairs) is actually being departed from the drive way... ( a lot).
2 years ago, that was the very small hair line crack... In this spring, I just noticed that it does now become a big Gap (>3/4~1/2 inch).
Considering the cold weather here in Michigan, that seems caused by water frozen and expantion... (maybe other reason...)
What would be the best solution? Just pouring any concrete sealer product? any recommended product for such application?
Any kind of advice will be highly appreciated...
