Why Flexstone?

We use Flexstone Coatings, Canada’s only building-code-approved waterproof membrane system. It’s trusted nationwide for balconies, decks, rooftop patios, and walkways—and we’re proud to be the exclusive certified installer in Southwestern Ontario.

Flexstone Benefits:

  • Seamless and flexible surface

  • Fully waterproof and weatherproof

  • Freeze/thaw and UV resistant

  • Optional textures and colours for a decorative finish

  • Long-lasting durability backed by warranty

Our Process

Every balcony project follows our proven multi-step system:

  1. Surface prep: Grind seams smooth, fill with urethane and seam tape

  2. Base coat: applied evenly using water-catalyzed urethane

  3. Color coat: Rolled on to provide adhesive layer for chips

  4. Broadcast chips: for texture and visual appeal

  5. Top coat: a clear, protective urethane seal for long-term durability

The result is a smooth, attractive, and fully waterproof surface that lasts for decades.
