Soil Retention Systems

Shotcrete for Soil Retention (shoring)
Safety Is Our First Priority

Typical excavations have room to safely slope or step the sides of the excavation. Inner-city excavations and last remaining lots in new subdivisions are limited in space and often require straight-cut excavations. OH&S regulation states that if an excavation is more than 1.5m deep, the wall needs to either be cut back or a protective temporary structure must be installed. If the excavation is more than 3m deep, the temporary protective structure must be designed by a professional engineer.

Working with Calgary Home Builders since 2010

  • Straight cut vertical excavations with no room for safe sloping.
  • Protection of neighboring fences, swales, trees, electrical boxes, power poles and sidewalks during excavation.
  • Property line retaining wall construction.
  • Cantilever Shoring System - for single level parkades - used as shoring and permanent foundation combined.
