How to build outdoor seating on cement retaining wall?

[DiFerguson]

Hi, I am keen to have a go at building some wooden seating to sit atop my cement sleeper retaining walls.

I have envisioned a decking look that has an overhang. I am thinking of creating frames for each 2m section, that sits inside the first level of wall and attaching boards parallel to long edge. I would like the bench to overhang the cement sleeper.

I have never done this before but I want to give it a go.  I have carefully pulled apart a pallet, removed all the nails and sorted ‘good’ from ‘bad’ to use for a trial run IF that is a good idea.  

Challenges: 1) The H bracket joins where the sleepers sit. 2) The big chunks of cement left behind by the landscaping (I think I will take a sledgehammer to these). 3) How do I create the nice overhang? (

4) Leveling each section so the frames sit square (I have crusher dust and a manual whacker packer. I also have a drop saw

I include photos of my site. The pallet wood I have for test runs and two Pintrest pics that are close to what I am thinking.

Thanks in advance, brains trust.

Hello @DiFerguson 

I suggest using CLR 750ml Oil And Grease Remover. It's formulated to remove oil, grease & tar stains.

I think I may have read your post to another person in the community, recommending this.

I will let you know how it goes.
