Replacing or Building a Post & Rail Retaining wall

On several  recent engineering & building inspection I noticed a few retaining walls that needed attention so I was asked to provide illustrative engineering drawing and easy to follow details.Whether you intend to build it as a DIY project or get someone else in to do the job..it's always advisable to have a good idea of how the project should be done properly. A few points to consider beforehand

  •  Check with your council building department 
  •  Generally a 2 person min. installation... remember Safety Always First (SAF)
  •  When in doubt always consult an engineer
  •  High retaining walls may require engineering certificationDIY Retain.jpg

Re: Replacing or Building a Post & Rail Retaining wall

Ooh, a good subject to bring up.

 

I'm looking at replacing a decrepid TP half logs, and was going to use 75mm slepers adn teh RetainIt Posts frmo Bunnigns to do so.

 

But, I'm a little puzzled on how to approach oe part of the wall.

Thepicture below shows the basic lay of the land and what the wall currently looks like.

The standard wall part, I'm fine with, its the part that runs up the slope that confuses me.

 

Currently the poles just run horizontaly and then end in the ground, without any footing or anything holding it firmly that I can see (aside from the fact that its packed under the soil).

 

Whats the best way to redo this side?  

Would I want to run all three sleepers the whole lengh and fix at a 3 riser post at the top of the slope? (which would be wholly burried)

Or run each sleeper a fraction of the way along, and use a single post at the end of each sleeper.

 

I should draw pictures to illustrate these, but I also shold get some work done today!

Hi MickOs
Thanks for the 3D drawing

On the sloping side elevation you can vary the plank length
