Surrey is the fastest-growing city in British Columbia, with a surge of mid-rise and highrise strata developments built throughout the 1980s, 1990s, and 2000s. Many of these buildings now have parkade structures with waterproofing membranes reaching the end of their service life. For strata councils in Surrey, addressing parkade waterproofing before failure occurs is one of the most important maintenance decisions you can make.
The Cost of Deferring Parkade Waterproofing in Surrey
A compromised membrane allows rainwater and road salts to penetrate the concrete slab and reach reinforcing steel. Once corrosion begins, it accelerates rapidly — especially in Surrey’s wet winters. The result is concrete spalling, structural compromise, and repair costs that grow exponentially with delay. Strata corporations that address waterproofing proactively typically spend 30–50% less than those who wait until structural damage is visible.
Surrey’s building stock includes a significant number of post-tension concrete structures, which require specialized attention during repair. Cutting into a post-tension slab without proper assessment can sever tensioned cables, causing immediate structural failure. Always ensure your contractor has experience with post-tension systems — see our post-tension cable repair services for more detail.
Common Parkade Waterproofing Problems in Surrey Buildings
The most common failure mode in Surrey parkades is membrane debonding — where the waterproofing layer separates from the substrate due to age, thermal movement, or improper original installation. This creates voids beneath the membrane where water pools and slowly infiltrates the slab. Other common issues include failed expansion joint seals, deteriorated drain flanges, and cracked traffic coatings on ramps.
Our inspections in Surrey have also identified a pattern of improper slope-to-drain design in older structures, causing chronic ponding that accelerates membrane deterioration even when the membrane itself is otherwise intact.
What a Surrey Parkade Waterproofing Project Involves
A full membrane replacement begins with removing the existing waterproofing system down to the concrete substrate. The concrete is then inspected, and any damaged areas are repaired before the new membrane is applied. Work is typically phased to maintain partial parking access.

Strata councils should obtain a written scope of work and budget estimate before approving a project. Our team provides detailed condition reports suitable for strata minutes and depreciation report updates.
