Retaining walls

[hotnuts21]

@redtop did you ever get this sorted? I need to replace a 2.4m high 7m long wall, holding back just soil of sloping garden. Thinking of just doing reinforced concrete block buy trying to get a SE in rural Wales  is proving difficult.

did it with gabions, took ages but was very cheap, 10 3/4 tonne bags of quarry waste at 20 quid a bag. chucked a few blocks in each basket as well and got enough facing quality stone from the quarry waste to face about 1 1/2 gabions per bag. rear gabion wall is 2M high but only 0.5M deep to reduce digging into rock, had to use vertical steels in concrete to make them more stable.

 

All works fine; cheap but slow and hard work.

What is the wall holding back???

I used this type of dry walling system on mine.

It can go to 3m high and requires no concrete base and it's a DIY job. The blocks are about 20kg each so it's heavy work but definitely doable.

What sort of money is in that per m2?

Sorry I can't really remember as it was a good 6 years ago. As I had bought my lightweight blocks for my house from them I was able to get a good deal. 

With not needing any concrete base or plastering and being a DIY task it must have worked out much cheaper than any other option to hold back my driveway or I wouldn't have used it.

So many variables with retaining walls I can’t see there being anything straight forward to use
