Under-Deck Waterproofing Systems Toronto & GTA

Create a Dry, Usable Space Under Your Deck
Transform the area beneath your second-story deck into a protected, functional living space with professional under-deck waterproofing systems. At Royal Innovation, we install advanced solutions like Trex RainEscape and EPDM membranes to ensure the underside of your deck remains dry, making it perfect for storage, outdoor seating, or entertainment.

Why Choose Under-Deck Waterproofing?

Standard decking leaves the space below exposed to rain and snow, limiting its use. By installing a waterproofing system, we channel water away from the substructure and keep the area beneath completely dry. This effectively turns your deck into a roof, creating new possibilities for covered outdoor living.

Key Features:

  • Complete waterproof protection for the space below your deck
  • Installation of Trex RainEscape, EPDM membrane, or similar systems
  • Turns under-deck areas into usable entertainment area or storage
  • Protects framing and substructure from water damage
  • Extends the lifespan of your deck and enhances property value

Our Waterproofing Installation Process

  • Assessment & Planning – We inspect your deck structure and design the right waterproofing solution.
  • System Installation – Install RainEscape troughs, EPDM membranes, or equivalent systems to divert water.
  • Drainage Setup – Ensure proper water channeling away from the house and foundation.
  • Finishing Options – Add ceilings, lighting, or fans to create a fully functional outdoor living area.
