Understanding Drilling Techniques: An In-Depth Look at Open Hole, Cased, and Slurry Methods
Open hole, cased, and slurry methods are primary techniques for drilled shaft construction, used by foundation drilling operators to create high-capacity deep foundations. Open hole methods are suitable for stable soils above groundwater. Cased methods utilize steel casing for unstable or caving conditions, while slurry methods employ stabilizing fluids for challenging subsurface environments with water […]
