Grout injection, otherwise referred to as injection grouting, is an effective method for repairing or strengthening masonry walls. This technique involves low-pressure injection of fine hydraulic lime grout into cracks, voids, and cavities within the masonry. This technique increases building resistance to moisture penetration and restores the material continuity across cracks. Grout injection is especially useful for restoring or stabilizing historic structures because the technique does not alter the building’s appearance. It increases the masonry’s durability and overall service-life by bonding wythes and reducing moisture infiltration.
