Observation Walk Deck Waterproofing With Pacific Polymers Elasto Deck System in Scottsdale, AZ

A homeowner in Scottsdale, Arizona chose SUNVEK for an out-of-pocket waterproofing installation on a new elevated observation walk deck. This was a retail project with no insurance claim or lender involvement, and the deck was part of an architectural addition that required a durable flat deck system capable of protecting the wood substrate while creating a usable outdoor living space.

The project covered approximately 245 square feet (2.5 squares) across a 0/12 flat deck area and included substrate preparation, parapet wall and scupper drainage integration, railing transitions, and a Pacific Polymers Elasto Deck 5000X2 pedestrian walk deck coating system finished in a clean tan surface to complement the home’s desert exterior.

Problem: New Elevated Deck Needing Reliable Waterproof Protection

The new observation deck required more than a decorative finish. Because it was built over structural wood framing and surrounded by parapet walls, the waterproofing system needed to protect the deck surface, wall transitions, and drainage details to prevent moisture from reaching the framing below.

The project also involved careful work around a custom architectural addition. New plywood decking, parapet construction, railings, wall penetrations, and scupper openings all needed proper treatment before the deck could become a finished outdoor space with the views and usability the homeowner envisioned.

Solution: Pacific Polymers Walk Deck System With Detailed Edge Protection

SUNVEK reviewed the new deck area and substrate conditions, then prepared the wood deck surface for waterproofing installation. The crew addressed deck edges, parapet bases, and wall transitions, and integrated the waterproofing around the through-wall scupper drainage area to ensure proper water management off the flat deck.

The Pacific Polymers Elasto Deck 5000X2 system was applied to create a durable, textured finish suitable for pedestrian use, with the installation carefully coordinated around railings, lighting, access points, and perimeter walls. The finished deck received a clean tan surface that matched the home’s desert exterior style, and the completed system is backed by a 5-year warranty.

Result: Protected Outdoor Living Space With a Clean Finished Surface

The completed waterproofing installation turned the elevated deck into a finished outdoor living area with improved protection and a clean, uniform surface. The new system safeguards the wood deck structure from moisture while maintaining the home’s architectural look, and the textured walking surface provides safe, comfortable footing for everyday use.

For the homeowner, the result was a functional observation deck that can be enjoyed with greater confidence. Rather than a basic surface coating, this installation addressed the deck as a complete waterproofing system — substrate preparation, parapet transitions, scupper drainage, and a durable walking finish — all backed by a 5-year warranty for long-term peace of mind.
