Restoring Remnants of the HBC Warehouse

Conserving a Downtown Landmark
Timeline

Mar - Oct 2025

Location

Victoria, BC

Client

City of Victoria

Situated along the Inner Harbour, the Wharf Street retaining wall stands as a significant remnant of the historic Hudson’s Bay Company’s warehouse and a prominent piece of Victoria’s waterfront history. We were commissioned by the City of Victoria to do a comprehensive replacement and repoint, addressing advanced stone delamination, brick deterioration and mortar failure. The aim was to preserve the wall with minimal intervention and considered heritage accuracy.

Prior to our involvement, the wall’s condition had reached a critical threshold. Material loss and the presence of internal voids required a modern conservation strategy to protect this founding piece of Victoria’s colonial heritage from further decline.

Objectives

  • Material Restoration: Repairs that matched the original stone composition.
  • Structural Stabilization: Filling internal voids below the sidewalk and restoring the wall face to prevent further movement.
  • Historical Accuracy: Utilizing lab-tested materials and traditional methods to ensure the restoration is indistinguishable from the historic fabric.

Unique Challenges

Urban Site Management

Completing a restoration in downtown Victoria during peak tourist season required rigorous site management. We maintained a compact footprint and safety protocols to ensure project continuity, without impacting the high-traffic of the Inner Harbour.

Minimal Intervention

In accordance with national conservation standards, our approach was defined by restraint. We saved original material wherever possible, intervening only where necessary to ensure the wall remained structurally sound.

Technical Scope of Work

The project utilized advanced conservation techniques to ensure the repairs blended seamlessly with the historic structure.

Key Conservation Measures

  • Custom Hot Lime Mortar: We performed detailed lab testing on the original 19th-century mortar to establish its composition. We then used traditional hot lime mixing to create a custom mortar that matched the historic material.
  • Sub-Surface Consolidation: Systemic filling of internal voids and structural cavities to restore the wall’s mass and stability and support the Wharf Street sidewalk overhead.
  • Face Repairs: Strategic removal of failed stone units and replacement with historically aligned masonry to weather-proof the exterior.

Collaboration

Effective conservation in the public realm requires transparent communication with both owners and the community.

Our team coordinated closely with:

  • The City of Victoria: As project owners, ensuring the work met municipal long-term performance goals.
  • Herold Engineering: Serving as contract administrators to oversee the structural outcomes.
  • Heritage Stakeholders: We hosted organized site tours for local heritage groups, sharing our technical approach with the local community.

Transformation

Before

  • Advanced masonry decay, failing mortar joints, and significant internal voids that threatened the wall’s long-term stability.

After

  • A structurally fortified waterfront landmark, restored with historically accurate hot lime mortar and stabilized stone and brick work honouring its industrial past.
