Cost of retaining wall

[Mortgage_tom]

I know its very hard to say without measurements, etc.

But I just need a basic idea of the cost of building a retaining wall here.



£10k max?

(sorry meant to post in homes, garden and diy.)

Ballpark £750/m presuming no piles required.

So £10k about right.

You need to act quickly OP, it's moved already!

Gabons, rock & labour. You can build a retaining wall easily for that amount.

Family member did the very same thing you are wanting to do.

PM me if you want pics & before/afters of it.

You need to make sure that the wall is actually going to retain the earth behind it. Structurally.

Thanks for the replies.

I will get a structural engineer to design it.

But I'm in early stages of negotiation for an offer/option on the plot.


In places it does look quite high and a considerable amount of ground above. Does it look like there could be a risk that it requires piles?

I'm guessing it starts to get expensive then?

Couldn't say for certain without investigatory boreholes / trenching to establish bearing level, really. Ballpark £1500 - £1800/m though.

£10k won't get much.

How high is it ?

How long is it ?

I presume we're talking about a concrete retaining wall, what are we facing it in ?

I was recently involved with similar and it was closer to £30k

I was quoted 14k for a much smaller retaining wall (brick) both in length and height. South East based. I went for vertical sleepers in the end as it was much cheaper and suits the surroundings better. Gabions as mentioned above could work?

Thanks for the info.

I went to look at in person this afternoon.

The bank is massive, a lot higher than it looks in the picture!

Im going to talk to a structural engineer before going any further.

Over the last two years we have used hundreds of metres of gabion baskets up to a height of about 3M, They were designed by a structural engineer and the stone was carefully chosen for the facings which is time consuming and will add cost but they do look really good, and much more interesting than a concrete or brick wall.

[jason61c]

That fact it’s retaining itself should help with Overall costs

[Andeh1]

I still see no reason why gabions wouldn't work. Foundation of MOT, then 1.5mx1m gabion then 2 lots of 1m^2 on top. Instant free draining wall that isn't going to move in the slightest. Budget easily doable for £10k.... Some reasonable foliage to hide and it all quickly becomes functional, attractive & affordable.

That looks about 18m by 2.5m high. If so £10k is optimistic in my opinion and I build a lot of them.

A detail like the below is what you could be looking at. Gabions are useful but ugly unless flat face filled ie. dressed stone carefully stacked to the face to look better. They also have a limited life and are classed as a 'flexible' retaining structure because they can move.

I'd suggest the below detail would cost (if my dims are somewhere close) approx. £13.5k to £15k but this very much depends on the location in the UK (I'm North Wales based). How near to concrete batcher etc.

'Retained Height' can be reduced by having a 45 degree slope to the back of the wall if that could work?

Sorry about the orientation.

So am I :-)

Do you build these?

Yes, we do. Although we tend to do more commercial projects we are not averse to private work for the right client.

Where about in North Wales are you?

Perhaps I could have a look at it for you or help you choose the right contractor using my knowledge of the area and the 'real' contractors compared to the joskins!

That'd be great. The plot is in Pentraeth on Anglesey, not far from Menai Bridge.

Where are you?

[Trophy Husband]

Conwy Valley based. Parents live on the island. Family from Penmon.

I'll PM you once I work out how to do it!!!
