New Westminster is one of Metro Vancouver’s oldest urban municipalities, with a significant stock of aging strata and commercial buildings — many featuring concrete parkade structures that are well past their original waterproofing lifespan. For strata councils and property managers in New Westminster, parkade waterproofing and concrete restoration represent critical maintenance priorities that affect both building safety and long-term asset value.
The Age Profile of New Westminster Parkades
New Westminster experienced substantial residential construction through the 1970s, 1980s, and early 1990s, producing a large inventory of buildings with parkade structures now 30–50 years old. Waterproofing membranes installed during original construction have long since exceeded their service life, and many have been partially patched or overlaid over the years — creating a patchwork of different materials and ages that complicates repair.
The downtown core and Uptown areas contain particularly concentrated pockets of older strata buildings where parkade conditions have deteriorated significantly. In many cases, water infiltration has been occurring for years before strata councils recognize the extent of the problem.
Concrete Restoration in New Westminster Parkades
When water infiltrates a parkade slab and reaches reinforcing steel, the resulting corrosion causes the steel to expand — creating internal pressure that fractures and displaces the surrounding concrete. This process, known as spalling, is both a structural and safety concern. Loose concrete falling from soffits or beams poses an immediate hazard to vehicles and occupants.
Concrete restoration in New Westminster parkades typically involves chipping out all delaminated and carbonated concrete, treating the exposed rebar (or replacing it where corrosion is severe), applying a corrosion-inhibiting primer, and restoring the profile with a structural repair mortar. This work is done prior to installing a new waterproofing membrane. Our concrete spalling repair services are specifically designed for parkade and strata environments.
Planning Waterproofing in an Occupied Strata
Waterproofing an occupied parkade in New Westminster requires careful logistics. The work must be phased to maintain access for residents who depend on their parking stalls. Our team develops phased construction plans in collaboration with the strata property manager, typically dividing the parkade into zones and completing one zone at a time while the others remain accessible.
Dust, odour, and noise management are also important considerations in occupied buildings. We use appropriate ventilation, barrier systems, and work scheduling to minimize resident impact throughout the project.
