New Azek deck sags between joists?

chester_2009October 9, 2009

Need some help with my new deck, It's a beautiful deck with Azek decking and composite railing,It's 17x20,10 feet high with 6x6 posts, and 2x8 joists ,12 on center.

The problem is the deck boards sag or flex between the joists, Is there anything I can do.

Intersting,even on a 12'' center joist system. The only thing to do is add more joists. It will probley sag less in cold weather. J.

According to their installation instructions, 16" OC for residential and at right angles to the joist and 12" for anything else.

Have you call Azek and asked them what's up?
