Why Do Concrete Slabs Crack? Exploring the Common Causes

Cracks on a concrete slab can occur due to various reasons. Here are some common causes:

• Overloading: Excessive weight or pressure can cause cracks.
• Weathering: Exposure to weather, especially freeze-thaw cycles, can cause cracks.
• Poor construction: Inadequate preparation, mixing, or finishing can lead to cracks.
• Shrinkage: Concrete shrinks as it cures, leading to cracks.
• Poor drainage: Water accumulation can cause erosion and cracks.
• Weak subbase: A weak or unstable subbase can cause cracks.
• Soil movement: Soil movement or erosion beneath the slab can cause cracks.
• Tree roots: Tree roots growing beneath the slab can cause cracks.
• Chemical damage: Exposure to chemicals, like salt or acid, can damage concrete.
• Thermal expansion: Concrete expands and contracts with temperature changes, causing cracks.
• Poor curing: Inadequate curing can lead to weak concrete and cracks.
• Settlement: Soil settlement or uneven foundation can cause cracks.
