The project

As part of the backyard renovation, we decided to build a deck as an entertaining area. We decided to use the existing concrete section and extend over part of the lawn area.

Steps

Step 1

We built the frame using H3 timber at 450mm centres, propping it up with some bricks.

Step 2 

We then added some joist tape to protect all the the timber. 

Step 3 

We levelled the deck using plastic pedestals and ensured it was flat.

We also applied more weed mat over the non-concrete area to avoid any potential weed growth.

Step 4

We then started installing the decking boards starting with the edges and then laying the boards using the Ekodeck quick fix system.

A low-level composite deck over concrete and soil by community member oninpena was completed after getting advice from resident Bunnings Workshop D.I.Y. experts Mitchell and Eric.

Hi @diy_hausdesigns,

I am Adi and i am planning to build a deck, just wanted ask do we need to anchor these plastic pedestals to ground?  if not then are they unstable?

Hi @BAditya,

Hopefully @diy_hausdesigns can let you know of their experience with the pedestal feet.

I've built a deck with them, and fixing them is unnecessary. The weight of the deck holds them down. I created a relatively small 3000 x 3000mm deck, and it's rock solid.

Hi @BAditya I did not anchor them in my build. The weight of the whole deck is more than enough to hold it down as @MitchellMc mentioned. 

I'd recommend taking the time adjusting the pedestals to be completely flat on the surface. I Had to do a few re-adjustments with the frame on to ensure everything was flat and it worked out well.

All the best
