How to repair shifting Versawall retaining wall?

[toffeeapple]

Hi All,

Looking to put new turf and soil. Dug out previous soil and turf. I don't see drainage inside wall but could be in the base (800mm high).

Landscaper who installed 5  yrs ago said because it's in the front yard, may not need drainage because it goes on to council land.

Hello @toffeeapple 

I'm currently looking at the photos you posted, but your question is about putting new turf. 

Let me start with your masonry fence, in regards to the gaps in your masonry fence, these often happen because of soil movement. Water has softened the base of your masonry fence causing movement. I propose looking at how water drains away from your fence next time there is a continuous downpour. You'll be able to determine where the bulk of the rainwater is going and how its interacting with your fence. You can then install an appropriate drain to divert water away from the fence.

I propose using Mortafil 450g Ash Grey Mortar to fill the gaps in the masonry fence. Please make sure to clean the gaps with a brush before applying the Mortafil.

In regards to your new turf, I suggest having a quick look at this guide - How To Lay Turf. This guide will give you a general explanation of how to prepare the soil and what you need to add to get it ready for new rolled turf. 

If you need further assistance, please let us know.

Hey Eric

It's the versawall retaining wall blocks.

Are you saying it's the base that has moved (first block) and that's the reason the other blocks has shifted?

Hello @toffeeapple 

It's my number one suspicion, and I can't imagine anything else that might move such a heavy structure.
