Question
What is grout in structural repair?
Expert Answer
In structural repair, grout refers to a highly fluid mixture of cement, sand, and water (often with polymers/resins) used to fill voids, seal cracks, or lock machinery base plates in place. Unlike mortar, which is a paste, grout flows. 'Non-shrink' grouts are essential in repair to ensure the material doesn't pull away from the edges of the void as it cures, maintaining a tight structural fit.
