Hi Guys, as for the grooves in the decking,as far as I was aware they are there to improve foot grip ??  The third board on the crossing Mike isn't for a siding its just to support the scenic backdrop stonework. Its already been cemented over and some stones laid on it since I posted the pictures. I'll post new pics in the morning .  

 

No, they belong on the bottom and are there to let the bottom "breathe" to wick away moisture as well as providing bite points for older hidden fastener systems. The breathing saves the deck joists at the contact points with the deck board versus the flat boards...at least that's what they want you to believe. Mother nature will eventually win.

Hi Carl, oh well, there you go ,ah learns sumthin every day, but over here everybody lays them groove side up hmmmmmm ??????? However I use them for everything but decking. Always find wood decking too ****ed slippery, especially in a wet climate like Scotland.
