To optimize the usable square footage within a site, many sites within the Lower Mainland are building their structures according to their minimum setback design. Another part of these designs can include construction of basements which will also allow for even more square footage.

At Valley Geo, our team can review your ideas for your proposed structure and work with you to determine a cost-effective solution to safely carry out the excavation and provide a safe working environment for the workers. We aim to provide immediate input when dealing with deep excavations or sites which require heavy temporary shoring. This ensures our ability to inform the client of the future costs associated with carrying out such work.  Once all excavations and shoring systems are in place, we ensure that the excavation meets the regulations from WorkSafe BC and that the site is safe for workers to enter.

Some examples of excavation shoring methods we typically use include:

  • Shotcrete + Anchoring
    • Used during deep vertical excavations in order to stabilize the slopes. It combines the principles of reinforced earth soil nail design and meshed shotcrete.
  • Underpinning
    • A method used to strengthen and stabilize the existing foundation’s structure. Underpinning extends the foundation in depth in order to rest upon a stable stratum or in breadth to distribute its load.
  • Sheet Piles
    • Are long, vertical interlocking sections driven into the ground to create a continuous wall. Its application can be permanent or temporary.
  • Temporary Lock Block Walls
    • Lock Blocks are interlocking, concrete blocks used to create a wall that stabilizes excavated areas.
  • Trenching
    • These boxes act as a safeguard to protect the workers within a trench in the event of a cave-in.
