i have trex planking with fasteners at each joist. it is an upper deck with epdm roofing underneath. nearby trees drop a lot of debris that falls between the planks and appears to accumulate and cause drainage problems. i would like to easily remove a plank or two every year to flush out debris with a garden hose. i am considering removing all the fasteners except those at the ends.
what will happen if plank fasteners are used only at the ends?
would there really be a problem given that side forces are neglible and gravity holds down the planks?
To make sure your decking is warranted by the manufacturer you have to follow the instructions.
Whilst it may seem plausible to fasten at the ends for ease of board removal it would not be advisable. It won’t be covered by the warranty and the boards will move. This is for ALL decking boards and by any manufacturer including softwood, hardwood and modified wood.
Maybe best to design a few inspection hatches for maintenance, this would be normal in this instance.
