What options for adjustable decking footings?

Hi, I have started building my backyard floating deck on existing pavers, I am planning to use the Builders Edge, but at certain points the height is more than the biggest of the Builders edge provides , which is the Bigfoot (170mm max height). I could use the Bigfoot at most of my points but there are certain spots the I need 300mm, are there other alternatives?

I could find this https://nurajack.com.au/products/nurajack-pro3-with-joist-head but not sure if I could trust these , has anyone used these before.

I looked at Goodtimes that uses the 150mm Modular Decking Adjustable Support Foot

https://www.bunnings.com.au/150mm-modular-decking-adjustable-support-foot_p8451186

But this also needs 140mm Modular Decking Support Steel and that adds up the cost ($30)

The other option I was thinking was using 3 concrete pavers 300x300x40mm , this gives me 170mm + 120mm, will this work?

TIA

Hello @coolnav

If you are needing framing support at 300mm++, I suggest using TuffBlock 300 x 300 x 90mm Instant Foundation System Deck Support. Please note that if you are putting this onto soil a paver will need to be placed under the footing. This will allow you to use a standard 100mm x 100mm post and cut it down to the height that you need (see image below). I'm sorry but the store currently does not stock Nurajack and the Goodtimes modular decking foot is not long enough.

Let me call on our experienced members @Dave-1 and @Nailbag for their recommendations.

If you have any other question we can help with, please let us know.

Hi @coolnav

I think you're already on the right path yourself along with those recommendations from @EricL . Another product that may proof to be useful are these adjustable mini-foots. There are a couple of variations to this that Bunnings stock.

Good Morning @coolnav

The footings that @EricL have shown with the post are pretty much the route I would go, that will give you the height you need and also solidly based. I have not used them but so many Bunnings community members have and I have not heard of any issues with them.

Quick update on this—thanks for your suggestion, @EricL I agree that your solution is the way forward. However, as a first-time DIYer, cutting 45 posts to varying heights felt like too much effort.

I looked into Nurajack but initially couldn’t find much information. After some research, I discovered that Bunnings NZ sells them. I had a conversation with Lewis from the Nurajack NZ team and felt confident enough to proceed with their product.

I ended up ordering the Nurajack PRO3 with Joist Head (155–420mm)—it’s priced similarly to Tuffblocks and also requires 90x90 posts.

I’ve attached a picture of the Nurajack PRO3 I used. It feels solid compared to another product I initially purchased but couldn’t use due to the required adjustable height.
