Waterproof Vinyl Decking, Built for Chilliwack
Tucked against the mountains at the east end of the Fraser Valley, Chilliwack catches some of the heaviest rain in the region, then bakes through hot valley summers. Valordek is a continuous, fully sealed waterproof vinyl membrane tested from -40°C to 80°C. Made in Surrey, an hour down the highway.
The wet end of the valley, then real heat
Chilliwack decks take a one-two punch: some of the heaviest rainfall in the Lower Mainland, then a genuinely hot valley summer. Few surfaces shrug off both.
Heavy valley rain
Backed against the mountains, Chilliwack catches more rain than most of the Fraser Valley — long, soaking winters that find every seam, board gap, and fastener hole. A continuous membrane has none of them.
Hot summers
Inland from the coast, Chilliwack summers regularly push into the low 30s. Heat warps boards and softens lesser surfaces; Valordek is tested to 80°C and stays dimensionally stable.
Rot and moss
Damp winters keep wood from drying, feeding rot and growing moss on timber and composite. Vinyl doesn't absorb water, so the surface and the structure under it stay dry and clean.
Floodplain damp
Built on the Fraser floodplain, Chilliwack sits with a high water table and damp ground much of the year. Sealing the deck surface keeps that ambient moisture from finding its way into the structure from above.
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 Chilliwack and the eastern Fraser Valley
Chilliwack has shifted from farm town to one of the valley's fastest-growing communities, and the building reflects it — new subdivisions in Garrison Crossing and Promontory, acreage homes out toward Sardis and Yarrow, and a steady run of townhouses and condos through the centre. Big valley properties tend to mean big decks and covered patios, all of which need to keep the heavy winter rain out of what's below.
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.
Why wood and coatings fail here first
Chilliwack's wet winters soak wood until it rots and grows moss, then the hot summers dry and check it — constant movement that splits boards and lifts coatings. A continuous heat-welded vinyl membrane doesn't absorb water, doesn't move with the humidity, and has no gaps, fasteners, or seams to fail. One sealed, colour-stable sheet.
Built for big valley decks
For large family decks and covered patios, the 68mil Fuzzy-Back gives a seamless, walkable waterproof surface; for anything over living space or a rooftop, the 60mil Smooth-Back adds PVC flashing and a fire rating. Both heat-weld into one continuous sheet, however big the deck.
Installing around the rain
Installation needs a dry substrate above 10°C, so in the wet east valley it's about timing dry windows. Chilliwack's hot, dry mid-summer is prime, and shoulder-season work is booked around clear spells.

Is vinyl decking good for Chilliwack's heavy rain?
It's built for it. Valordek is a continuous, fully waterproof PVC membrane — no board gaps, fastener holes, or open seams for the valley's heavy winter rain to get through, and it doesn't absorb water, rot, or grow moss the way wood and composite do.
Will it handle hot Chilliwack summers?
Yes. The membrane is tested to 80°C and stays dimensionally stable through the low-30s heat the inland valley sees in summer — it won't warp or soften the way boards can.
What does vinyl decking cost in Chilliwack?
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.
Is it a good fit for a large deck or covered patio?
Yes — it heat-welds into one continuous sheet at any size, so big valley decks and covered patios get a seamless waterproof surface with no joints to leak. Contact us for a quote on your project.
Can it be installed during the wet season?
Installation needs a dry substrate above 10°C, so jobs are scheduled around dry windows rather than a fixed date. Chilliwack's hot, dry mid-summer is prime; shoulder-season installs are booked around clear spells.
