Earth Retention Systems include three main areas: Slurry Walls, CBSP Walls and Secant Pile Shafts. All three of these sections are outlined below along with links to some of our work. If you are looking for more information, be sure to visit our Contact Page to request more information.
A Slurry Wall is a technique used to build reinforced concrete walls in areas of soft earth close to open water or with a high ground water table. This technique is typically used to build diaphragm (water-blocking) walls surrounding tunnels and open cuts, and to lay foundations.
Cement Bentonite Solider Pile Walls also known as CBSP is a cost effective means for a watertight support of excavation that has little to vibration to adjacent structures. CBSP is typically used for temporary open-cut structures.
Secant piles are drilled shafts constructed in such a way that the shafts overlap each other to form a wall. The construction sequence involves drilling every other shaft and then returning after the concrete has set in the initial shafts to drill and pour the shafts for the secondary piles. Secant piles are used to build cutoff walls for the control of groundwater inflow and to minimize ground movement.
