The Company has employed a new method for designing and manufacturing Precast Shafts for construction process called Open Caisson Sinking. This has replaced the previous method Cast in Place, for the sake of time-saving and reducing traffic problems. The Precast Shafts are in circular and rectangular forms(ranging from 1.20m to 6.80m in size). We also produce Interceptors (IPC or CSO) and other types of manhole.
