Correct Answer:
C. Grouting
Explanation:
The correct answer is Grouting.
Grouting is a construction technique used to fill voids, cracks, or gaps in structures like masonry, concrete, or soil to enhance structural integrity and provide waterproofing. The process involves injecting a fluid material—typically a mixture of cement, sand, and water, or specialized resins—into the targeted areas where it eventually hardens. This method is essential for repairing damaged foundations, sealing joints against water ingress, and strengthening existing infrastructures. While curing involves maintaining moisture for concrete strength and ramming or tamping refers to compacting materials, grouting specifically addresses the filling of internal spaces for repair and protection.
