Earth Retention & Shoring is the process of containing soil in the event of an organic, unsteady slope or man-made excavation and supporting existing adjacent structures when necessary. HJ Foundation pulls from years of experience and an impressive technique range to deliver ideal solutions specific to your project needs.

Common Uses

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

Earth retention and shoring systems are complicated to design and construct in some cases for a number of reasons including weather conditions, depth of cut and ground water, bordering development, overlapping loads, soil structure, vibrations, and seismic loads. It’s important that the design address the bottom of excavation’s stability while underneath the water table.

Structures, construction machinery, and stored accessories near an excavation create lateral loads on a retention system. Underpinning neighboring structures can curtail the loading on the wall of an excavation and accumulation of settlement. Vibrations from road traffic, railways, blasting, and other machines in nearby buildings can affect excavation shoring.

Typical 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 may be used to support sheeting and shoring systems laterally. Access shafts for tunneling and trenchless construction can involve a circular shoring system designed to act as a compression ring. Construction shoring for ongoing excavations may need to be protected from the elements. Utmost care is imperative in shoring excavations where safety is key. We acknowledge the risks related with earth shoring and the significance of trench safety. HJ is the shoring company with the experience and inclusive range of techniques to deliver dependable earth retention and shoring services.
