Overview
A cold joint is where a fresh batch of concrete meets one that has already been cured. It’s hard for uncured concrete to form a seal with a block that’s been cured already. Therefore, a cold joint is the area where cracks are more likely to form, followed by water infiltration. For below-grade construction, waterstops represent a safe, commonsense approach to preventing water infiltration through seams in concrete.
