  • The cold joint is blocked

    The cold joint is blocked

    Repairing cold joints isn't just a good idea; it's essential for maintaining the integrity of your concrete footings. A cold joint in concrete is an area or surface with a structural discontinuity caused by the delayed concrete pouring between two layers of concrete. The delayed placement prevents full integration and knitting between the concrete batches and might lead to reduced structural robustness, increased. Cold joint concrete is a common problem in the construction world. It's important for construction professionals to understand what causes cold joints and how to manage them effectively.
