Every crack in concrete isn’t just a defect it’s a diagnosis waiting to be understood. From early shrinkage to long-term chemical reactions, each pattern reveals something about how the concrete was designed, placed, or cured. Here’s a quick breakdown of the most common types of cracks we encounter on site 👇 🔹 Plastic Shrinkage Cracks – Appear soon after pouring when surface moisture evaporates too fast. 🔹 Settlement Cracks – Diagonal or irregular cracks caused by uneven foundation movement.

Welding Hot Cracks🔥 Hot cracks (also called solidification or liquation cracking) are among the most dangerous welding defects. They form at high temperatures, near the solidus, when the weld is still partially molten and extremely brittle. 🔍Where do they occur? · Weld Metal → Solidification cracking (centerline of bead). · HAZ → Liquation cracking (partially melted zone). ⚠️ Why and when do they happen? · Lack of ductility at high temperature. · Impurities (S & P) segregating at grain boundar
