Waterproof Vinyl Decking, Built for Maple Ridge
Maple Ridge decks tend to be big — acreage sundecks and covered patios under the Golden Ears, soaking through long Fraser Valley winters. Valordek is a continuous, fully sealed waterproof vinyl membrane tested from -40°C to 80°C. Made nearby in Surrey by 25-year waterproofing pros.
Big decks, long wet winters
The larger the deck, the more seams and surface there is for water to attack — and Maple Ridge gives it a long, wet Fraser Valley winter to work with.
Heavy Fraser Valley rain
Sitting against the mountains on the north side of the Fraser, Maple Ridge catches heavy rainfall through a long winter. On a big deck that's a lot of square footage for water to find a way in. A continuous membrane gives it none.
Rot under the trees
Shaded, treed acreage lots stay damp and drop debris that holds moisture against a deck. Wood rots and grows moss; vinyl doesn't absorb water, so it stays sound underneath whatever the forest drops on it.
Big spans, more seams
Large sundecks and covered patios mean long runs and more joints in board or coated systems — every one a potential leak. Valordek heat-welds into a single continuous sheet no matter the size.
Cooler valley winters
Tucked north against the mountains, Maple Ridge runs a touch colder than the coast and sees the occasional snow and freeze. The membrane stays flexible to -40°C, so it doesn't crack in a cold snap.
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.
Serving Maple Ridge and Pitt Meadows
Maple Ridge has the mix that defines the northeast valley: established homes in central Maple Ridge, newer subdivisions climbing toward Silver Valley and Albion, and acreage and semi-rural properties out toward Websters Corners and Pitt Meadows. The common thread is space — bigger lots, bigger sundecks, and covered outdoor rooms meant to be used through the rain under the Golden Ears.
The National Building Code treats any deck or balcony over occupied space as a roof — it has to be waterproofed to CGSB 37.54 standards, not just surfaced. Valordek's membranes carry CCMC and Intertek certification confirming they meet code 37.54.95.
Built for big rural decks
This is where a continuous membrane earns its keep. A large board or coated deck has dozens of joints and fastener lines, each one a leak waiting to happen over a wet winter. Valordek heat-welds into one seamless sheet across the whole span — the 68mil Fuzzy-Back for open sundecks, the 60mil Smooth-Back where the deck sits over a suite, shop, or carport.
Why wood and coatings fail here first
Shaded, treed lots keep wood damp and pile on debris that traps moisture; the wood rots and grows moss while paint-on coatings lift at the edges. A continuous vinyl membrane doesn't absorb water and has no gaps, fasteners, or seams to fail — it just sheds whatever the winter and the trees throw at it.
Installing around the rain
Installation needs a dry substrate above 10°C, so work is timed to dry windows. The valley's warm, dry mid-summer is prime; shoulder-season jobs are booked around clear spells.

Is vinyl decking a good fit for a large deck?
It's ideal for it. Valordek heat-welds into one continuous sheet at any size, so a big sundeck or covered patio gets a seamless waterproof surface with no joints to leak — a real advantage over board or coated decks where every seam is a weak point.
Is vinyl decking good for Maple Ridge's wet, treed lots?
Yes. The membrane is fully waterproof PVC that doesn't absorb water, rot, or grow moss — so the shade, damp, and debris that come with treed acreage lots don't break it down the way they do wood and composite.
What does vinyl decking cost in Maple Ridge?
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.
Can it go over a deck that sits above a shop or carport?
Yes — that's what the 60mil Smooth-Back membrane is for. It seals a deck built over a suite, shop, or carport to the CGSB 37.54 code standard, with PVC flashing and heat-welded seams. Contact us to spec your project.
When can it be installed?
Installation needs a dry substrate above 10°C, so jobs are scheduled around dry windows. The valley's warm, dry mid-summer is prime; shoulder-season work is booked around clear spells.
