Continuous flight auger (CFA) piles are drilled and concreted in one continuous operation enabling much faster installation time than for bored piles. Reinforcement is placed into the wet concrete after casting, enabling the pile to resist the full range of structural loading.
Soil nailing uses grouted steel nails to reinforce in situ soils and create a gravity retaining wall for permanent or temporary excavation support.
Rigid inclusions is a ground improvement method using high deformation modulus columns constructed through compressible soils to reduce settlement and increase bearing capacity.
Ground improvement efficiency depends on the stiffness relationship between the soil and the columns. Load from…
This technique involves the improvement of weak soils by the installation of densely compacted columns made from gravel or similar material with a vibrator. The displacement process reinforces all soils in the treatment zone and densifies surrounding granular soils. It’s a technique first…
