Shrinkage cracks are small fissures that can develop in materials like concrete or soil as they dry and lose moisture. This process occurs when the material contracts, leading to visible cracks on the surface. These cracks are typically superficial and do not compromise the structural integrity of the material. The formation of shrinkage cracks is influenced by factors such as temperature, humidity, and the rate of drying. While they are common and often expected, excessive shrinkage can lead to more significant issues if not managed properly. Regular monitoring and maintenance can help mitigate their impact.
