How to build a deck on a concrete slab backyard?

[romeo]

Been thinking of starting a small deck project (around 2800 x 5500) on my backyard with a slightly uneven concrete. I had always been planning to use Tuffblock and just fix any minor unevenness of my joist. But was thinking maybe it's safer to use the Buiilders Edge since the height is adjustable.

Any suggestions for now between these 2?

Cheers

Hello @romeo 

If the entire deck will be going onto the concrete base, then it would be better to use the Builders Edge Pedestal Feet as it is adjustable. Whereas the TuffBlock 300 x 300 x 90mm Instant Foundation System Deck Support is not adjustable. I also suggest having a quick look at these guides - How to build a low-level deck by @Adam_W and How to build a deck by @MitchellMc.
