Grout F-20 is an injection grout based on natural hydraulic lime from St-Astier. This grout is specially formulated for the consolidation or reinforcement of voids in solid masonry. Grout F-20 presents a very high fluidity that allows the grout to pass through the empty spaces of the foundation to coat and solidify the wall mass. Grout F-20 will remain homogeneous despite its very liquid state. Grout F-20 can be applied by injection or gravity.
