How to build a small deck using Decko footings?

Samc1234

I pan building a deck platform using concrete DECKO footings. The deck platform will roughly be 3.5m x 1.5m. I am wondering:

What will the frame structure under the deck look like?

What wood will I use for the frame structure?

What screws are best used when using merbau wood?

When placing the DECKO concrete, do they sit on gravel or do I need to cement them in?

How many DECKO concrete footings do I need for a high traffic area? (the deck will not have any furniture on it)

Thank you again, 

Sam

Hello @Samc1234 

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about the DEKO footing.

I 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. these guides will give you a general idea about what the frame structure could look like, what wood to use along with what screws to use. After reading the guide I suggest drawing on paper your decking frame plan using the DEKO footing blocks. Since the deck is not so big you should be able to draw this up easily. 

I also suggest having a look at this featured project - Low-level composite deck over concrete and soil by @oninpena. It is an excellent example of a single level deck that uses 90x45 H3 treated timber. The DEKO footing can accept 90x45 H3 framing timber easily. The soil footing must be tamped hard so that the DEKO footing does not sink.  

I also suggest looking at the Bunnings deck building guide:

• How to plan out your deck
   
• How to set out a deck
   
• How to install stumps
   
• How to install bearers
   
• How to install joists
   
• How to lay decking
   
• How to add a step to your deck.
