SERVICES EQUIPMENT MEDIA ABOUT US LOCATIONS RETENTION SYSTEMS DIAPHRAGM WALLS Structural Diaphragm walls, also known as slurry walls, are typically excavated using a Mechanical or Hydraulic clam shell bucket in vertical panels from grade to create the below grade wall to design depth. During excavation, a bentonite or polymer slurry… Read more SECANT PILING Secant piling is a robust, rigid system which can be used to construct combined earth retention and groundwater cut-off walls. The continuous wall is constructed by drilling overlapped concrete piles with diameter typically between 2 and 4 feet. A wide… Read more SOIL MIX WALLS Soil mixing improves the engineering properties of soil by injecting cementitious grout and blending the materials in-situ. Soil mixed walls are constructed by overlapping elements of soil mixed ground, and inserting structural piles for reinforcing. Soil mixed walls offer a… Read more SOLDIER PILE WALLS Soldier pile walls provide a core system for earth retention in both temporary and permanent applications. Structural “soldier” piles are installed from original grade. Then, as the site excavation proceeds in lifts, lagging is placed between the piles to retain… Read more SOIL NAIL SYSTEMS Soil nail systems stabilize a section or block of retained ground by installing closely spaced grouted steel rods into the exposed face as the excavation proceeds downwards. This approach provides a flexible, cost-effective and efficient earth retention solution. The rows… Read more SLOPE STABILIZATION Malcolm’s drilling and grouting expertise is applied to safely and securely reinforce existing unstable slopes and to allow re-grading for development of new facilities. Our slope stabilization projects employ post-tensioned anchors, stitch piers and dewatering in addition to more conventional… Read more GET IN TOUCH WITH US NOW!
