CGEs are vertical grout columns for ground improvement and ground reinforcement. Installation is accomplished by full or partial displacement and the placement of fluid cement grout within the evacuated volume. CGEs can improve granular soil and reinforce both granular and fine-grained soil below shallow foundations and floor slabs. Berkel can design a cost-effective subgrade improvement or reinforcement system for all soil types including fills and clays. Berkel's engineers can provide a ground improvement plan that is suited to the requirements of your project.
