Ground Improvement

Horizontales
A method that's is used to lower the ground water table, both assisting excavation efforts at depth, and also increasing the effective stress in a soil, which leads to strength gain.
A tool used to accelerate settlement in low-permeability soils.
A ground improvement process that could include low-slump materials to densify a soil mass, or jetted materials to provide groundwater cutoff or excavation support.
It could consist of grout, timber, or steel; this is a ground improvement technique where stiffening elements are installed to provide foundation support and reduce settlement in soft soils.
A process used frequently in geoenvironmental applications, where panels of soil are mixed with a hardening agent to stiffen the soils, while also containing environmentally-sensitive soils.
A ground improvement method that involves dropping heavy weights from a crane to densify the existing subsurface soils at a given site.
Lime and Portland Cement are commonly used in this application, often for roadway and pavement subgrade improvement efforts.
A ground improvement technique that involves actively removing excess pore pressures from a soil mass under load.
An up-and-coming segment of the ground improvement field, where carbon-based microbes are used to stabilize and solidify soils at depth.
Typically required in low-shear-strength soils, this can be introduced in a variety of ways to improve the shear capabilities of a soil mass.
In soft, cohesive soils, this is an approach that's used to accelerate long-term settlements by placing an amount of load well above to the dead and live loads to be experienced by the soils at depth.
Verticales
The process of particle rearrangement into a tighter configuration, increasing the strength and density of the soil mass.
A medium- to low-energy approach to ground compaction.
A method of densifying the subsurface that introduces a large, vibrating probe.
A ground improvement approach that introduces refrigerant to the subsurface to temporarily freeze the soils; used extensively in tunneling and excavation support.
One of the oldest forms of ground improvement, this technique involves the introduction of stone during the densification process to both densify the surrounding soils, and to introduce ground stiffening elements.
Load is applied to soft, cohesive soils equal to the load to be felt to accelerate consolidation of foundation soils before construction.
Can be done using either the wet or dry method; it’s a method where a binding agent such as lime or cement is blended with soil to improve the load-bearing capabilities.
A ground improvement technique where densely packed aggregate is backfilled into an augured cavity to provide a stiffening element that provides foundation support.
Involves the use of explosives at depth to densify a soil mass.
