Earth Retention & Shoring involves retaining soil subjected to either a natural, unstable slope or a man-made excavation and when required, supporting existing adjacent structures including:

• Support of excavation
• Shore existing adjacent structures
• Stabilize natural or man-made slopes
• Bulkhead/wharf support and remediation
  
  

The design and construction of earth retention and shoring systems can be complex due to the soil structure, depth of cut and ground water, weather conditions, superimposed loads, seismic loads, vibrations, and adjacent construction. The design must address stability of the excavation bottom when below the water table.

Buildings, construction equipment, and stockpiled materials located adjacent to an excavation result in lateral loads on the retention system. Underpinning of adjacent structures can reduce the loading on an excavation wall and reduce the risk of building settlement. Excavation shoring can be affected by vibrations from traffic, railways, blasting, and machines operated in adjacent buildings.

GSET's permanent and temporary shoring systems include steel sheet piling, soldier piles and lagging, jet or chemical grouting, secant or tangent piles and soil nail walls. Anchors or bracing can be used to provide lateral support of sheeting and shoring systems. Access shafts for tunneling and trenchless construction may involve a circular shoring system designed as a compression ring. Also, construction shoring for excavations that are open for extended periods of time may require protection from weather conditions.

GSET understands the need for extreme caution  during any shoring excavation, and safety is of utmost importance. We understand the hazards associated with earth shoring and the importance of trench safety. We have the experience and the full range of techniques to provide reliable earth retention and shoring.
