Excavation Walls are installed to protect a work site and its adjacent surroundings from collapse due to an excavation – usually required to install a new, deep foundation, basement, to repair underground utilities or deep excavations required to remove spoils (contaminated soils).

Excavation Walls are usually installed in horizontal sections with sheet piling or H piles and wood timbers and whalers. Depths of 50' or can be achieved and the walls can be removed or abandoned depending on project requirements.

Soil Nails are used to retain hills, berms, retaining walls and other demising structures where the angle of repose is steeper than allowable and sliding soils become a concern. They are effectively used on golf courses, undulating landscaped areas and gun ranges.
