I have been thinking of a way to replace an existing deck & provide a water resistant it only covers another deck below so full waterfroof is not needed. I also HATE the gaps in normal decking as they are leaf & stick traps. Leaves will not move when blowing & sweeping is not much better. You have to pull gumleaves out one by one - a PAIN. A flat surface would be so much less work.
I don't want to use compressed fibro & tile as it will be too thick, to messy to install (lots of cutting) & too heavy.
I can not put sheet roofing (such as trim deck or csutom orb) below the joists due to construction issues & also I don't like the look of this system.
I have investigated aluminium decking from G James http://www.gjames.com.au/brochure/sunlanderdeck.pdf which has built in guttering, so the water resistance & ease of installation would be there - but I'm not sure that aluminium is the look I want.
I had looked at composite decking (mix of sawdsut & plastc) before, but the installation requires a minmimum 4mm gap for expansion, so no ability to make a water resistant surface. However, I noticed recently that ModWood have released a new 137mm x 23mm solid board that spans 450mm (their older system was hollow, & it also would not span the 450mm joists) . This got me to thinking. These composites can be worked with normal woodworking tools, so maybe I can route the boards to a shiplap profile to allow for movement, while providing the falt, water shedding surface I want.
What do you think - will it work?
BTW, the composites do not have issues with cupping & movement is supposed to be quite minimal - mainly thermal rather than moisture.
