Merbau decking is the number one choice if your deck is in a weather exposed situation because of its high levels of durability but more so because Merbau is an extremely stable timber choice so has less tendancy to twist and warp if correctly installed. One thing to take care of with Merbau is the release of tannin when it gets wet, this will not continue indefinately and there are ways to limit it happenning, call us to discuss.
