Dec-Tec Water Proof Decking

Where Dec-Tec Waterproof Decking Excels

Balconies and Rooftop Decks

These are some of the most common uses for Dec-Tec water proof decking. It provides full waterproofing protection while allowing full use of the space above. It’s perfect for projects in Tacoma, Bellevue, and other Washington cities where elevated living space matters.

Flat Roof Decks and Terraces

Convert flat roof areas into usable spaces with confidence. The membrane meets all low-slope roofing requirements while offering a finished, walkable surface ideal for gatherings or personal enjoyment.

Stairs and Landings

Wood stairs and landings are prone to warping and becoming slippery. With Dec-Tec, walkways remain sealed and grippy, even in rain-heavy locations like Bonney Lake or Everett.

Pools and Spa Decking

CoolStep finishes are popular for poolside or spa areas. They reflect sunlight to keep surfaces cooler and prevent overheating underfoot, all while remaining waterproof and mildew-resistant.

Multi-Unit Complexes

In apartments, townhomes, or condos, Dec-Tec water proof decking is ideal for shared breezeways and walkways. Its uniform look, durability, and low-maintenance design reduce repair costs and elevate property value.

Professional Installation from Trusted Local Experts

Comprehensive Site Evaluation

Every job starts with a detailed inspection of your structure. We assess slope, substrate condition, and drainage to make sure the surface is ready for proper membrane bonding.

Membrane Application and Seam Welding

We install the Dec-Tec water proof decking system using mechanical fastening and heat welding. This ensures that all seams are sealed tightly and the membrane performs as a continuous, watertight surface.

Edge Finishing and Accessories

Proper detailing is essential for long-term durability. We install flashing, trim pieces, and drainage components to complete the system and protect corners, terminations, and transitions from water ingress.

Warranty-Backed Protection

All Dec-Tec water proof decking installations by Chase Construction North West qualify for manufacturer warranties. These cover both the membrane itself and the quality of certified installation. Once complete, we provide maintenance guidelines to help you keep it looking and performing like new.

Built for Washington Weather

Long-Term Protection Against the Elements

Dec-Tec water proof decking holds up against the Pacific Northwest’s biggest threats: moisture, algae, and seasonal shifts. Unlike traditional wood decking that can crack or warp, the membrane stays intact and requires almost no ongoing upkeep.

Low Maintenance with High Visual Appeal

Whether you’re a homeowner in Renton or managing a property in Puyallup, you’ll appreciate how easy it is to maintain. Just wash with mild soap and water. There’s no need to stain, reseal, or replace damaged boards.

Stylish Design Built In

Classic Line options like granite tones or wood-inspired textures blend easily with exterior finishes. Light-reflective CoolStep shades help reduce surface heat in direct sun. Whether your style leans rustic or modern, there’s a finish to match.
