Professional Balcony & Deck Waterproofing Services

Balconies and decks are highly vulnerable to water intrusion because they are horizontal surfaces directly exposed to rain, snow, and standing water. Failed waterproofing can lead to serious structural damage, water infiltration into living spaces below, and costly repairs.

Our comprehensive waterproofing services protect your balconies and decks with proven membrane systems and professional installation that stands up to Vancouver's wet climate.

Warning Signs of Failed Waterproofing

  • Water stains on ceilings below balconies
  • Cracked or peeling deck coating
  • Standing water that does not drain
  • Soft or spongy deck surface
  • Rust stains from corroding railings

Our Waterproofing Solutions

  • Liquid-applied membrane systems
  • Sheet membrane installation
  • Traffic coating systems
  • Drainage improvements
  • Flashing and detail repairs

Waterproofing Systems We Install

Polyurethane Membranes

Liquid-applied polyurethane creates a seamless, flexible waterproof barrier that bridges cracks and accommodates building movement.

Best for: Concrete balconies, parking decks

PMMA Systems

Polymethyl methacrylate (PMMA) provides fast-curing, highly durable waterproofing that can be applied in cold weather.

Best for: Quick turnaround projects

Traffic Coatings

Durable, slip-resistant coatings that provide waterproofing while creating an attractive, walkable surface.

Best for: Pedestrian decks, patios

Our Waterproofing Process

1

Inspection & Assessment

We thoroughly inspect the deck or balcony, identify existing problems, and assess the substrate condition.

2

Surface Preparation

Proper preparation is critical. We remove failed coatings, repair concrete damage, and ensure proper slope for drainage.

3

Detail Work

Critical areas like drains, edges, and wall transitions receive extra attention with reinforcing fabric and additional membrane layers.

4

Membrane Application

We apply the waterproofing system according to manufacturer specifications, ensuring proper thickness and coverage.

5

Quality Verification

We conduct flood testing and final inspection to verify watertightness before the deck is returned to service.
