Waterproof Vinyl Decking, Built for Vancouver Island
From the Cowichan Valley to Campbell River, Island decks live with mild but constant marine damp and ocean salt air. Valordek is a continuous, fully sealed waterproof vinyl membrane that doesn't rot, grow moss, or corrode. Made just across the strait in Surrey by 25-year waterproofing pros.
Mild, but never dry
Vancouver Island's easy temperatures hide the real problem: relentless marine moisture and salt air that quietly work a deck apart over the years.
Constant marine damp
Most of the Island gets a long, wet winter with rainfall that climbs sharply the further north you go. That persistent damp keeps wood from ever drying, feeding rot and moss. Vinyl doesn't absorb moisture, so it doesn't care how long the wet season runs.
Ocean salt air
On an island, few decks are far from saltwater. Salt-laden air corrodes fasteners and breaks down coatings and untreated wood. A continuous membrane with no exposed fasteners removes the parts salt attacks first.
Moss country
Cool, shaded, and damp much of the year, the Island is prime moss and algae territory. Wood and composite green over; vinyl has no grain for moss to grip and rinses clean.
Bright dry summers
Island summers are sunny and increasingly dry, fading stain and checking wood between the wet seasons. UV-stable vinyl holds its colour year-round — no annual re-stain.
Two membranes. Built for two jobs.
Valordek bonds directly to your substrate and heat-welds into one continuous waterproof surface. No board gaps, no fasteners through the surface, nothing for meltwater to find.
68mil Fuzzy-Back
The standard for residential balconies and decks over living space. Contact-adhered with heat-welded seams for a fully sealed, walkable waterproof surface.
60mil Smooth-Back
Built for rooftop and amenity decks. PVC flashing on open decks plus heat-welded seams. Class A & C fire rated and Intertek tested.
Communities we serve across the Island
Valordek ships across Vancouver Island and connects you with local installers. Wherever you are on the Island, the same continuous membrane handles the marine climate — here's a closer look at the communities we serve. (Looking for the capital? See our dedicated Victoria page.)
Cowichan Valley & Duncan
The Cowichan Valley bills itself as the warmest region in Canada, with a Mediterranean lean and a strong wine-country and acreage market. Decks here run big and get used most of the year — and still face the wet Island winter. A continuous membrane keeps those large valley decks sealed without annual upkeep.
Nanaimo & Parksville
Mid-Island's hub and its retirement-heavy coastal strip are full of view decks and condo balconies looking out over the Strait of Georgia. Salt air and damp are the constants; a membrane with no exposed fasteners and no absorbent surface is built for waterfront exposure.
Comox Valley & Courtenay
Courtenay, Comox, and Cumberland sit where the mountains meet the ocean, with a fast-growing mix of new builds and retirement homes. Higher rainfall than the south Island means even more reason to seal a deck completely rather than chase leaks every winter.
Campbell River & the North Island
Up the coast, Campbell River and the North Island get the Island's heaviest rain and rawest marine exposure. This is where wood and coatings fail fastest — and where a continuous, salt-air-proof vinyl membrane earns its keep most.
Why wood and coatings fail here first
Across the Island the slow killers are moisture and salt rather than cold. Damp keeps wood from drying, feeding rot and moss; salt air corrodes fasteners and lifts coatings from the edges. A continuous heat-welded vinyl membrane doesn't absorb water, has no exposed fasteners, and no seams to fail — one sealed sheet that shrugs off the marine climate.

Is vinyl decking good for the Island's damp climate?
It's built for it. Valordek is a continuous, fully waterproof PVC membrane that doesn't absorb moisture, rot, or grow moss — exactly what the long, damp Island winters do to wood and composite. No gaps, fasteners, or open seams for water to get through.
Will salt air affect it near the ocean?
The membrane is inert PVC that salt air doesn't corrode, and a proper install has no exposed fasteners — the parts salt attacks first on a wood or coated deck. It's well suited to the waterfront and near-ocean properties found all over the Island.
Which Island communities do you serve?
We ship across Vancouver Island and connect you with local installers — the Cowichan Valley and Duncan, Nanaimo and Parksville, the Comox Valley and Courtenay, Campbell River and the North Island, and more. Victoria has its own dedicated page.
What does vinyl decking cost on the Island?
The membrane starts at $3.74 per square foot for material. Total installed cost depends on deck size, substrate condition, and complexity. Size your project with the cost calculator, or reach out for a quote.
Will moss grow on it like my old deck?
No. Vinyl has no grain or open surface for moss to take hold and doesn't hold moisture — a real advantage in the Island's moss-prone climate. A periodic rinse and soft-brush wash keeps it clean, with no sanding or re-staining.
