SAK is an expert in the excavation and construction of shafts in a range of ground conditions. In soft ground, we often employ conventional excavation methods with the installation of shaft supports such as liner plates or rib and lagging. In wet or soft ground, we can install sheet piling and sink caissons to build a watertight retaining structure. In rock, we use either mechanical excavation or drilling and blasting to install shaft supports such as rock bolts and shotcrete. Regardless of ground condition, a licensed engineer designs every shaft support system SAK installs.
