Repairing cold joints in concrete is essential for maintaining structural integrity. Conventional methods like epoxy grout injection can address cracks effectively. Where the two are distinguished, it is rather in the definition of a crack and that of a concrete joint. What is the difference between a cold seal and a crack? Even if we sometimes tend to confuse them, a crack. When fresh concrete is placed against concrete that has already begun to set, it creates a visible discontinuity where the two layers do not bond properly. If this is not achieved, there is insufficient adhesion subsequently. A cold joint in concrete, also known as a construction joint, is a point in a concrete structure where fresh concrete is placed against previously cured or partially cured concrete.
