Earth Retention

Earth retention is needed for various reasons, including re-mediating areas with compromised slope stability, providing support at excavation sites, and deep cuts. A variety of techniques can be used for earth retention. The technique utilized per application is based on the following issues: level of instability during construction, space available for systems during construction, access, depth of excavation, schedule, and cost of construction.

Gibson’s Pressure Grouting offers custom solutions, most frequently using anchor systems, soil nailing, and tiebacks. Our geotechnical engineers can assess your project site to determine the most cost effective solution for your needs.

Problems such as sinking foundations, tilting slabs or columns and structural cracks are often caused by subsurface soil conditions that were not known at the time of construction or have occurred since the structure was built. Retaining walls can bend crack or buckle because earth pressures behind them become greater than it's design strength. Additionally there exist specific structural techniques that are time-tested to provide additional support to the structures themselves.

Gibson's structural improvement services include anchor systems designed to resist uplift or turning, and drilled & grouted mini-piles as well as helical pier and other underpinning techniques to offer additional vertical support to problem foundations.
