The process of extracting fasteners embedded within hardened cementitious mixtures is often necessary during renovation, demolition, or repair work. These fasteners, designed to provide secure attachment points, can present challenges during removal due to their embedment and the bonding characteristics of concrete.
Effective extraction is crucial for maintaining structural integrity, preventing damage to surrounding materials, and ensuring a safe working environment. Historically, various methods have been employed, ranging from brute force techniques to more refined procedures that minimize disruption to the concrete matrix. The selection of an appropriate method depends on factors such as anchor type, size, depth of embedment, and the condition of the surrounding concrete.
