This solution aims to provide an equivalent improved soil mass stiffness to globally reduce total and differential settlements by sharing loads of the structure between the ground and the CMCs. There is no limitation in use for any type of weak grounds, including soils with significant organic content (peat, organic clays, etc.), and the technique can uniformly support slab-on-grade and shallow footings, spread footings, strip foundations, and retaining walls. The use of a rigid inclusion ground improvement enables the reduction of the cost of the structure (decrease of concrete thickness and steel reinforcement). The entire process is vibration-free and does generate a very limited amount of surface spoil, which allows a cleaner job environment and limits the risk of contamination.
They are an economical alternative to traditional deep foundation solutions and can prove to be beneficial for the global design of the overlying structure.
