SHOULD DECKING RIDGES FACE UP OR DOWN??
The reeded side of the timber boards make for interesting patterns that look sleek and pleasing, thus begging some people to install them face up.
People also lay the decking timber ridge side up because they think that the ridges help increase traction and make the deck less slippery.
However, the proper way to install a board is ridge side down. The ridges, are designed to let air circulate underneath the boards.
This prevents the buildup of moisture and consequently, mould.
The ridges are not there to keep you from slipping and sliding around your deck. Nor are they intended to make your deck look nice.
They are there as a structural feature to improve its longevity.
