The myth about Decking ridges
In decking construction there is one question that is sure to ignite passionate argument: Should decking ridges face up or down?
There are debates that just won’t end.
Decking timber usually has ridges that run along the length of the board. Also called “grooves” or “reeds”. These ridges on the board may face up to provide functionality and aesthetics. Or they may be installed facing down, the orientation recommended by manufacturers as the correct way to install them.
