Mechanical Stabilization
Mechanical Stabilization involves physically altering the soil using methods like compaction, blending, and confinement to increase its strength and stability.
Chemical Stabilization
Chemical Stabilization uses additives such as lime, cement, or fly ash to improve soil strength and reduce permeability.
Electrokinetic Stabilization
Electrokinetic Stabilization is the use of electrical currents to move water and ions in the soil, consolidating and strengthening it.
Geosynthetic Stabilization
Geosynthetic Stabilization includes the use of synthetic materials, such as geogrids and geomembranes, to reinforce soil and improve its load-bearing capacity.
Thermal Stabilization
Thermal Stabilization involves altering the temperature of the soil, using techniques like freezing or heating, to improve bearing capacity and stiffness.
Biological Stabilization
Biological Stabilization makes use of vegetation and microbial processes to enhance soil stability and reduce erosion.
Grouting Stabilization
Grouting Stabilization involves the injection of grout to fill voids, consolidate the soil, and increase its load-bearing capacity.
Hydration Stabilization
Hydration Stabilization is a process where water content in the soil is optimized to achieve maximum density and strength.
