I need to extend a garden by about 10ft, which currently drops down a
steep embankment to a lower level 12ft below. The width of the garden
is about 20ft.

I could just dump tons of rubble down there, but then I will end up
with a slope. I wanted to construct something which would retain the
rubble to create a steeper drop.

An initial idea was to create a retaining wall by stacking 'grab-bags'
which contained a dry mix of aggregate. I would do the mixing and
loading with a mini-digger. I could then backfill with the rubble.

Building a retaining wall with bricks would be another idea, but I
think it would work out more expensive in terms of materials and
labour.

Any other suggestions?

I have a 1.8m retaining wall, thats part of my house, its not too
expensive

Breifly

1.2 m wide 0.3 m thick foundation with 2 steel mesh, and 12mm upright
bars, then 2 thickness of 7N blocks with the middle filled with
reinforced concrete.

I did this as a DIY project.

A strutrial engineer will design one for your site for a hudred quid
or so.

I'd guess at 2 grand total cost, assuming you DIY most of it, and site
access is good.


You could use gabions, steel cages filled with rocks. In anycase I'd
talk with an engineer. if this lot moves, you will be in deep donkey
doo-dah

You will have to make provision for drainage. Water retained behind
something like this can be very destructive. The gabions may be self
draining but I would let some other expert declaim on this. If a solid
wall is used then drainige pipes incorporated along the base may be the
way to go. Consult an engineer.
