Thanks, looks a good shout and am tempted to mix and match with
sandbags. I'll have a closer look.


Send us a photo of the damage. Structural retaining walls needing
to hold back a considerable amount of wet soil need careful thought.

It is quite a difficult location to get a good view of what has
happened.

This picture https://ibb.co/qJCGgvZ is taken on the top of the path
that I am clearing so to the left is the 30' or thereabouts of steep
area going up to the back of the property and the right goes down
about 20' to a lower area.


That's a very steep slope !

The retaining wall has not been damaged as far as I can see, I haven't
exposed all of it, and the wall did not extend at that height for the
whole length of the path that I am exposing.

From what I can see the wall does not seem particularly well made
or substantial.
I wonder what sort of foundations and rebar reinforcement it has ?.

There are a couple of trees and more shrubbery further on blocking the
path which winds down to the right past all that mess. I've got an
axe, saw and a chainsaw.

A slope that steep is probably stabilised by roots. Proceed with
caution before you remove too much.
