Grout injection is a process commonly used for floor stabilization. It involves injecting a cementitious grout material into the voids and gaps beneath a floor to fill any voids and provide additional support.
The process of grout injection typically involves drilling holes into the floor in a pre-determined pattern, usually at regular intervals. The size and spacing of the holes depend on the nature of the floor and the extent of the damage or instability.
The grout material is then injected under pressure through the holes using specialised equipment, such as a grout pump or injection gun. As the grout material is injected, it fills the voids and gaps beneath the floor, and begins to solidify and harden, providing added support and stability.
