dassoXTR 3-in-1 Bamboo Plank for GRAD Installation System
dassoXTR 3-in-1 Bamboo Plank is designed for use with the GRAD Speedy Installation System.  The plank is called 3-in-1 because a single plank can be used as either decking, siding or soffit. dassoXTR's 3-in-1 Bamboo Plank has a convex surface to allow natural drip-off to prevent water from sitting on the surface of the plank.  The backside of the plank is routed to allow direct snap-on of the plank to the diamond shaped GRAD clips which are attached to an alluminum tracks. The clips on the aluminum track is pre-set and does not require the installer to mess with the track.  Each plank and gap between planks are always consistant.  You will never get it wrong.
Below list some of the common questions you need to ask yourself when installing a decking project:
    - What is the type of subfloor you are building on (gravel, grass, concrete, or waterproof membrane…)?
 
    - What is your deck height (from floor to top of decking board)?
 
    - What is your joist spacing (16 or 24’’ oc)?  
 
    - What is your required uniformed loading (general office space required 60psf, typically we use 100psf to allow for safety factory)?
 
    - Is there a slopes on your subfloor (different slopes will call for different decking heights and accessories all over the deck)?
 
    - Do you have drawings to help with take-off and material planning (showing all dims)?
 
 
 
Backyard Deck
For a standard backyard deck, install Starter Rail-1902 on the deck joinst.  Ensure the diamond clips are align parallel to one another.  Snap the 3-in-1 plank on the clips and your job is done.
Pool Side Deck
For a pool side deck, place GRAD pedestal on the subfloor.  Snap on Joist Rail-1802-PR39 on the pedestal.  Ensure all the diamond clips are align parallel to one another. Snap the 3-in-1 plank on the clips and your job is complete.  
Rooftop Deck
For the rooftop deck, first consider how much clearance do you have from your roof to your exit door.  If your clearance is less than 4 inches, than your only option is to use the Starter Rail-1902 directly on the roof surface.  If your rooftop has TPO membrane, then place additional layer of TPO as cushion under the Starter Rail-1902. You could either let the track float freely on the roof or spot-glue the Starter-Rail to the additional cushion TPO.  Now, you can snap the 3-in-1 plank on the track just like the backyard deck.
On the other hand if your rooftop clearance exceed 4 inches, then you could opt to use the pedestal on the rooftop just like how you would install the pool side deck.  Likewise, use additional layer of TPO as cushion under each pedestal. Lastly, snap the 3-in-1 plank on the clips and your project is complete.
