– Structural cracks
– Settlement cracks
– Shrinkage cracks
– Joint deterioration
– Impact damage
– Pattern cracking
– Environmental stress cracks

Common Causes of Cracks in Concrete Floors:

1. Shrinkage During Curing: As freshly poured concrete dries and hardens, the mixture naturally loses moisture, causing the slab to contract slightly. If this shrinkage is significant or rapid, it can lead to small, hairline cracks on the surface. 2.Improper Installation and Mixing: Using too much water in the concrete mix or failing to adequately prepare the subbase can weaken the slab’s integrity. Poor workmanship, such as inadequate consolidation, can also create internal voids and weaken the slab, making it more prone to cracking. 3. Soil Movement and Settlement: Shifting or uneven settling of the soil beneath the concrete slab can create voids or uneven support, leading to stress and cracking in the floor.

Types of concrete cracks

Structural cracks affect the stability and integrity of the concrete structure.
They are typically caused by excessive loads, poor construction practices, or foundation settlement and require immediate attention.

•Flexural Cracking: Occurs due to excessive bending from heavy loads or insufficient structural support.
These cracks run parallel to the structure’s length or perpendicular to the applied force.

•Overloading Cracks Develop when concrete bears more weight than designed. They are often seen in heavily trafficked areas like driveways.

•Corrosion Cracks: Result from the rusting of embedded steel reinforcement, which expands and causes internal pressure, leading to cracking.

•D-Cracking: Caused by freeze-thaw cycles affecting coarse aggregates that trap moisture, leading to parallel cracks near joints.

Non-Structural Cracks

Non-structural cracks are usually superficial and do not compromise the structural integrity of the concrete.
They are often related to environmental conditions or material properties.

•Plastic Shrinkage Cracks: Occur when the surface of freshly poured concrete dries too quickly compared to the underlying layers, causing shallow cracks.

•Plastic Settlement Cracks: Form when wet concrete settles unevenly due to inadequate formwork support during setting.

•Crazing/Map Cracking: A network of fine, shallow cracks on the surface due to rapid drying during curing.

•Shrinkage Cracks develop as concrete loses moisture during curing, causing it to contract. They are common in driveways and slabs.

•Expansion Cracks Result from temperature-induced expansion and contraction of concrete and often appear as straight lines across surfaces.

Why Repair Concrete Cracks Promptly?
