The process of filling the cracks, open joints, voids, or leakage is known as Injection grouting. This process is done on Masonry Structural Members or in Concrete under pressure by using a material that cures the place from its roots and provides you the desired results like preventing water leakage and strengthening the structure. Grout is a flowable plastic material and has negligible shrinkage it helps in filling the gaps or voids completely and it remains stable without cracking, crumbling, or de-lamination. There are many different types of grout like cement grout, polymer-cement slurry, epoxy, urethane, and high-molecular-weight methacrylate (HMWM).
