We pride ourselves on understanding your needs to provide you with a shoring solution that works specifically for your project, not a one-size-fits-all solution that is lacking in both practicality and cost effectiveness. To accomplish this, we employ a range of earth shoring engineering solutions for deep excavations including H-piles, mechanically stabilized earth walls, sheet piles, soldier beams, geogrid, geofabric, geofoam, lagging, pre-manufactured trench boxes, secant pile walls, soil nailing, and cantilever walls. Our firm has successfully engineered many difficult, technical and high profile earth shoring projects across the United States.
Sheet piling uses interlocking steel sheets to create a continuous barrier that provides lateral earth support. The interlocking sheets are installed along the excavation perimeter to create either a permanent or temporary retaining wall or cofferdam. The steel sheets are often installed using a vibrating hammer, t-crane or crawler drill.
Mechanically stabilized earth walls (MSE) utilize one of or a combination of geosynthetic materials, soil nails, and other mechanical means of stabilization. This method reinforces the earth to prevent sliding.
Soldier Pile and Lagging systems typically use vertical, steel H-piles (beams) with horizontal lagging placed between the piles to stabilize an earth slope. The H-piles are first driven or dilled into the ground along the excavation face then lagging – usually wood, steel or precast concrete panels – is placed behind the H-beam flanges to create a retention wall.
Soil Nails are for an earth retention technique that involves inserting rebar or other slender reinforcing bars (the “nails”) into pre-drilled holes in the slope and grouting them into place with cement. The bars are usually installed at a slightly downward angle in regular intervals across the face of the slope. A rigid facing – often shotcrete (concrete that is sprayed onto a surface), nail head plates, wire mesh or erosion-control fabrics – is then placed on the surface to stabilize the slope.
Secant Pile Walls are often used for foundations, retaining walls and groundwater barriers. Concrete piles are installed leaving space between them for the secondary concrete piles, which are usually reinforced with rebar cages or steel beams. The secondary piles are installed parallel to (but offset from) the primary piles and act as lagging. The result is continuous line of overlapping concrete piles that creates a strong, watertight wall.
Cantilever Shoring is a common retaining wall technique usually used for projects where the height of the excavation is 20 feet or less. These walls are often made from steel-reinforced concrete or masonry built in the shape of an inverted T, or they can be built using soldier beams and lagging. The horizontal pressure of the earth behind the wall is transferred to the large, vertical structural footing on the ground.
