🧱 Concrete joints: how to control cracking before it appears 📐| Design Expert INT

📏 Concrete cracking cannot be completely avoided, but properly planned joints help control where it occurs. In slabs-on-ground, control joints are used to guide shrinkage and temperature cracks, while isolation joints are placed at walls, columns, and other restraint points to allow movement and reduce stress concentrations.

📐 As a practical guideline, control-joint spacing is commonly set at 24 to 36 times the slab thickness, with saw cuts at least one-quarter of the slab depth and not less than 25 mm. Rectangular or nearly square panels are also preferred, because irregular layouts and sharp angles increase the risk of cracking outside the intended joint pattern.
