I put this topic on the Flooring Section and although 73 people read it no one answered, perhaps the wrong trade.

Hi, I am a roofing contractor Down Under (NZ), who does a bit of deck membrane work using the trafficable PVC (vinyl) membrane sold under the various brands such as Duradek, Dec-K-ing, Weatherdek, Dec-Tec etc, mostly sourced out of Canada's West Coast. My research shows that most of these membranes are actually manufacturered in Mississippi USA, some are fibreglass reinforced, some polyester, some fleece backs, and historically find their way back to Sarnafil out of Switzerland.
One or two of them describe the product as "outdoor flooring" which I suppose it is, but I look at it primarily as a waterproofing membrane first, which you can also walk on.

Just wondering if there is anyone on this Forum who
1. does this type of work also?
2. has used this type of product as a re-moldeler/builder?
3. what your opinions are on the system if you have used it?

I am not trying to sell anything here , just asking , as we have been through them all and found the best for us here under our climate conditions.

If you are not sure about the product, throw a .com behind any of the brand names I mentioned above to see the products, and put it up on your web address bar.

burnit, I scanned your previous post and knew that I had seen the stuff somewhere, just couldn't remember where. Duradek is used on boat decks in Canada as a non-skid surface. That's about all that I can tell you though.
As a membrane, all that I would worry about would be the seams. They don't really matter on a boat as the deck is already watertight.

Teetorbilt, yes this is where the product came from, boat decks.
My understanding is that originally it was not reinforced.
It surprises me that no one here has come across the membranes mentioned as the marketing from all those companies tells us that it has been around for 20 years in Canada and the USA.
By the time it gets to us here in New Zealand it is quite expensive, and normally only used over habitable areas, such as on the flat roof of a first storey where you can walk out onto it from the second storey level.
We call these RoofDecks.
We only use the thicker 60mil material.
The laps are 1" and hot air welded, never had any problems with leakage. ;)

I have seen feature projects on those web sites, where they are ground level decks, 1-2 feet off the ground and would probably fit within the Landscapers section of works.

here in Edmonton we use dura-dek alot, I have never installed it myself but have framed many decks that were finished with this product. considering our climate here I am very impressed by this product. it is becoming more popular, and almost done on every multifamily buildings with many balconies. with proper installation this I think is the best way to finish decks off today on most modern homes.

BKFRAMING, I am currently bidding a DuraDek job that's to be applied over an 20x14 existing deck (one story above ground) protruding from the back of a home. I've been searching for a practical way to add pitch to the deck since it has no room for sleepers (the door exits at deck level). The customer needs the deck to have the reccommended pitch and to do so, I'd have to cut the beams to lower the outer edge of the deck. The only problem being that the staircase is on the outer edge. Have any design/modify ideas? I'm also thinking that I'll have to charge the woman about what it would cost for a new deck just to cover my a$$.

Did you get an answer to the pitch problem, We are faced with the same situation here..
