SYNOPSIS

Deep soil mixing (DSM) techniques is one of the common ground improvement technique in Malaysia. This technique involves in mixing the soil with chemical binder such as cement to form a high stiffness composite material. The main benefit of this technique is that it can be used in all type of challenging soil (e.g. estuarine or swamp) or on challenging geology (e.g. Karstic Formation). DSM can be adopted to improve soil bearing capacity, improve shear strength for slope stability or to act as a retaining wall. This webinar will be sharing a case study of using DSM as a temporary retaining wall for a 5 – 10m excavation works. The sharing will give an overview of the design method, prediction summary, construction challenges and monitoring results during excavation.
