Understanding Concrete Cracks

Concrete, despite its robustness, is susceptible to cracking due to various factors such as environmental conditions, structural loads, and material properties. Understanding the nature of these cracks is crucial in determining the appropriate repair strategy. Concrete cracks can be categorized into several types, including shrinkage cracks, settlement cracks, and structural cracks, each with distinct characteristics and causes.
