How to attach Ekodeck onto concrete sleeper retaining wall?

[DIYHome]

Hi community,

Would need some advice on covering our concrete sleeper retaining wall at the front of the house please

We have already purchased ecodeck decking boards to cover them but need to know we are doing the right thing before we start.

I understand that we need to fix timber onto the steel post and then affix the ecodeck as you would normally do and same as the capping. Below are my questions pls

1) What type of screws should I use to fix timber onto steel post ? Do I also need to glue the timber as well ?

2) Sleepers are 2m wide and the wall is 600mm height , so we are thinking of 2 treated pine timber one on the top and one somewhere in the middle https://www.bunnings.com.au/70-x-35mm-outdoor-framing-h3-treated-pine-2-4m_p8032103

3) How to fix the capping ? Steel post is 100mm wide and sleeper thickness is 80mm if that helps 

Appreciate your help

Thanks !

Hello @DIYHome 

That is perfectly alright, you can ask as many questions as you like. It's always best to do a test fit with the timber to make sure that it lies flat on the concrete sleepers. If does lie flat, then I recommend using Selleys 290ml Liquid Nails Instant Hold Construction Adhesive. Make sure to be generous on its application so that it will not lift off the concrete.

If you need further assistance, please let us know.
