Parkade Traffic Deck Membranes & Waterproof Coatings

Why Parkades Need Traffic Deck Membranes

Parking structures are constantly exposed to water, chlorides (de-icing salts / road brine), oil and fuel drips, and aggressive tire turning. On exposed decks, UV and freeze–thaw accelerate cracks and surface breakdown.

A properly designed traffic deck membrane creates a seamless waterproof barrier that helps prevent chloride ingress, reduces corrosion risk, and protects occupied spaces below from leaks.

• Blocks water and chloride intrusion into concrete
• Improves traction for vehicles and pedestrians
• Protects reinforcing steel and minimizes spalling
• Creates cleaner, brighter decks with marked lanes and zones

Common Parkade Problems We Solve

• Water leaks — membranes protect suites, retail, and storage below.
• Chloride corrosion risk — reduces salt/brine exposure to concrete and steel.
• Slippery drive lanes — tuned texture for safe traction on wet decks.
• Cracks, spalls & failed joints — repairs completed before waterproofing.
• UV & movement stress — flexible urethane wear layers handle thermal cycling.

Addressing these early reduces long-term capital spend and helps keep the property safe and presentable.

Traffic Deck Coating Systems We Install

Vehicular Traffic Deck Membranes (TDM)

These are multi-layer waterproofing systems designed specifically for vehicle decks. Typical builds include primers, membrane layers, reinforcement where required, broadcast texture, and protective wear coats.

Polyurethane / Urethane Waterproof Membranes

Urethane membranes add flexibility, UV stability, and strong weather resistance—ideal for exposed top decks, podiums, and areas that move with temperature and structure dynamics.

Epoxy Primers & High-Wear Base Layers

Epoxy is often used for bond strength and chemical resistance in priming and base coats, especially in covered levels. Many parkade systems combine an epoxy base with a flexible urethane membrane.

Fast-Return Polyaspartic Wear Coats (scope-dependent)

For projects where access must be maintained, select fast-cure systems can support staged reopening. Timing depends on temperature, prep, detailing, and required membrane thickness.

Ramps & Turning Lanes (Specialty Traction Zones)

Ramps and high-turn zones often need higher traction and wear resistance. We build these areas with broadcast texture and durable wear coats while maintaining cleanability and drainage. For ramp-specific details, see: Ramp Epoxy Flooring Solutions .

Our Parkade Membrane & Coating Process

We follow a documented process so your system performs as expected and aligns with warranty requirements:

1. Assessment: identify leak paths, wear zones, joints, slope/drainage issues, and failure points.
2. Concrete & joint repairs: spalls, cracks, and failed joints are rebuilt before waterproofing.
3. Mechanical prep: shot blasting / grinding to achieve the correct profile for adhesion.
4. Primers & base layers: bond-promoting layers to lock into the substrate.
5. Membrane build: waterproof layers with reinforcement where required (details vary by deck condition).
6. Broadcast traction: tuned texture for ramps, turning lanes, and pedestrian routes.
7. Wear coats: UV-stable, traffic-rated protective coats for longevity and appearance.
8. Handover: walkthrough, system documentation, and maintenance guidance.

We can provide phasing plans, signage, and access coordination to keep disruptions controlled.

Case Study — Downtown Vancouver Multi-Level Parkade

A mixed-use property experienced recurring leaks, spalling, and worn coatings across multiple levels. We removed failed materials, completed concrete and joint repairs, then installed a reinforced waterproofing build with traction broadcast and UV-stable wear coats on exposed areas.

Work was phased so sections remained open. After completion, the owner reported no further leak intrusion in targeted zones and improved deck appearance and traction.

Frequently Asked Questions

How long do parkade membranes and coatings last?

With correct repairs, prep, and maintenance, traffic deck systems can last 8–20+ years depending on exposure and traffic volume.

Can a traffic deck membrane stop existing leaks?

Yes—once cracks, joints, and detailing are corrected, a waterproof membrane can stop further water ingress and protect areas below.

What’s the difference between epoxy and polyurethane in parkades?

Epoxy excels at adhesion and chemical resistance (often used as a base). Polyurethane/urethane adds flexibility and UV stability (ideal for waterproofing + wear).

Will the parkade be closed during installation?

Most projects are completed in phases. Closures depend on scope, safety requirements, detailing, and cure times.

Do you provide warranties?

Yes—material and workmanship warranties matched to the selected system, plus care guidelines to protect service life.
