soil strengthening grouting
Use of micropiles and jet grouting are common methods in underpinning. An alternative to underpinning is the strengthening of the soil by the introduction of a grout, including expanding urethane-based engineered structural resins. Underpinning may be necessary where P class (problem) soils in certain areas of the site are encountered.
