A Secant Wall Shoring system is a specialized retaining structure used in deep excavation projects to ensure stability and structural support. This technique involves drilling and installing a series of reinforced concrete piles that overlap or “secant” each other, forming a continuous, interlocking barrier. Secant Wall Shoring is highly effective in soil retention and groundwater control, making it ideal for deep basements, underground construction, and excavation in challenging soil conditions. Its robust design enhances safety and minimizes ground movement, ensuring secure excavation in demanding environments.
