Parkade Traffic Coating Vancouver
A parkade traffic coating is a waterproof, wear-resistant membrane system for parking decks, ramps and underground parking levels. On a suspended deck it keeps water and road salt out of the concrete and away from the rebar, and off whatever sits below. On an on-grade level it seals the slab and gives drivers and pedestrians grip. We coat strata, commercial and rental parkades across Greater Vancouver in phases, so the building keeps parking while the work is done.
What Water and Salt Do to a Vancouver Parkade
Every car that drives into a parkade between November and March carries rain and road salt off the street. That salty water sits on the deck, soaks into the concrete and works its way down through cracks to the steel reinforcing. Once the rebar starts to rust it expands, the concrete above it pops off, and the repair bill moves from coating money to structural money.
On a suspended deck, the level with parking or occupied space underneath, the same water also drips through onto cars, storage lockers and electrical rooms below. That is usually the first sign a strata council hears about. By then the membrane, if there is one, has already failed in places.
- Leaks and white staining on the ceiling of the level below, often along cracks and joints.
- Rust stains and spalling where chunks of concrete have popped off the deck surface.
- Worn-through coating in the drive aisle, at ramp transitions and at the turn into each stall.
- Standing water around blocked or badly placed drains.
How a Parkade Traffic Coating Is Built
A traffic coating is a layered system, not a single coat of paint. Each layer does one job, and the build changes between the drive aisle, the stalls and the ramps.
| Layer | What it does |
|---|---|
| Concrete repair and prep | Spalls, cracks and failed joints are repaired and the deck is ground or shot-blasted so the system can bond |
| Primer | Bonds to the concrete and seals the surface so the membrane grips |
| Base membrane | A flexible polyurethane layer that bridges hairline cracks as the deck moves with temperature and load |
| Wear coat with aggregate | A harder layer with sand or quartz broadcast in, which takes the tire wear and gives grip |
| UV-stable topcoat | Locks in the aggregate and protects the system on exposed decks and ramps |
Drive aisles, ramps and turning areas get a heavier wear coat than parking stalls, because that is where tires scrub. Once the coating cures, stall lines, numbers, arrows and pedestrian walkways are repainted to the layout you have now, or a new one if the strata wants to change it.
Membrane or Epoxy: It Depends on the Deck
The first question at a parkade assessment is what is under the slab, because that decides what the deck needs.
| Deck type | What it needs | Why |
|---|---|---|
| Suspended deck, ramps, rooftop parking | Flexible waterproofing membrane with a wear coat | Occupied space below, and the slab flexes and cracks, so the system has to stretch without splitting |
| On-grade slab, lowest parking level | Epoxy or polyurethane coating with aggregate | Nothing below to protect, so the job is sealing, dust control, grip and appearance |
| Parkade storage rooms and bike rooms | Epoxy or sealer | Light traffic, mostly about dust and cleaning |
Putting a rigid epoxy on a suspended deck is one of the most common mistakes we see. It looks good for a year, then cracks with the slab and lets water straight through. Putting a full membrane on a slab on grade is the opposite mistake: money spent on waterproofing that has nothing to protect.
Parkade Coating for Strata and Property Managers
For most strata buildings the parkade membrane is a line item in the depreciation report, with a recommended replacement year and a budget. Send us that section before the site visit. We scope the work to match the report's language so the council, the property manager and the owners are comparing like with like.
- Assessment. We walk the deck, sound the concrete for hollow spots, check the drains and joints, moisture test and photograph problem areas.
- Written scope and quote. Repairs, the system for each area, phasing and a schedule, in a format you can put in front of owners.
- Notice to residents. A phase map showing which stalls are closed on which days, so the property manager can send notices and arrange temporary parking.
- Phased install. The deck is done in sections, usually a row of stalls or one half of a drive aisle at a time, so the building never loses all of its parking.
- Lines and handover. Stall numbers, lines and arrows are restored and the deck is walked with the property manager before each phase reopens.
Overnight and weekend work can be arranged for commercial parkades where daytime closures are not an option.
What a Parkade Coating Costs
Parkade work is quoted per project after a site assessment, because the deck itself sets most of the price. Two parkades of the same size can be priced very differently once the concrete has been sounded.
- Concrete repair. The amount of spalling, delamination and exposed rebar is the biggest variable, and it can only be measured on site.
- Deck type. A waterproofing membrane on a suspended deck costs more than an epoxy coating on a slab on grade.
- Old coating removal. Failed membranes have to come off before a new one goes on.
- Phasing. More phases and after-hours work add time on site.
- Drains, joints and line work. Expansion joints, drain details and the line layout are all priced into the scope.
For on-grade commercial and warehouse slabs, typical per square foot ranges are on the industrial and warehouse flooring page. You get a written quote with every repair item listed, so nothing is added once the work starts.
Making a Parkade Membrane Last
A traffic coating on a suspended deck typically lasts 10 to 15 years, and the wear coat in the drive aisles is usually refreshed partway through that life. The cheapest way to reach the long end of that range is plain maintenance.
- Wash the deck in spring to get the winter's salt off before it sits all summer.
- Keep drains clear. Standing water is what finds every weak spot.
- Walk the deck once a year and patch any worn spots in the aisles before they go through to concrete.
- Recoat the wear layer when the aggregate starts to wear smooth, rather than waiting for the membrane below to be exposed.
Parkade Coatings Across Greater Vancouver
We work on strata, rental and commercial parkades throughout Metro Vancouver and the Fraser Valley, from high-rise towers in Vancouver, Burnaby and Richmond to low-rise strata buildings in Surrey, Langley and Coquitlam.
Individual strata garages and private home garages are a different job, covered on our garage floor coating page. For all other commercial floors, see commercial epoxy flooring.
Balconies, walkways and rooftop decks on the same building take a similar membrane. See our balcony and deck waterproofing page for how we plan those for stratas.
