Cold joints are useful

Control joints are intentional and beneficial, designed to manage cracking in a controlled manner. But do you know what concrete cold joints are? 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. A contraction joint is formed, sawed, or tooled groove in a concrete structure to create a weakened plane to regulate the location of cracking resulting from the dimensional change of different parts of the structure. This discontinuity occurs because the older material has passed its initial setting time, preventing a true chemical bond with the fresh mix. These sneaky little rascals can turn your sturdy foundation into a wobbly mess faster than you can say “oops. Spoiler alert: it's not the kind of party you want. Concrete, being a mix of cement.
