Ivan_England Posted February 2, 2020 Share Posted February 2, 2020 I need to build a retaining wall for my driveway and wondered how much this would should cost roughly. It is in Surrey and is roughly 5.5 metres long and 1.2 metres high at the highest point. Link to comment Share on other sites More sharing options...

Declan52 Posted February 2, 2020 Share Posted February 2, 2020 What's the boundary on the left hand side made from?? Link to comment Share on other sites More sharing options...
Ferdinand Posted February 3, 2020 Share Posted February 3, 2020 There are a number of systems out there which use interlocking concrete blocks. If you dig in the( forum or the blogs, perhaps via Google, there are many threads. Link to comment Share on other sites More sharing options...
Ivan_England Posted February 3, 2020 Author Share Posted February 3, 2020 Hi, Thanks for this. I will look into them. On the left hand side (while looking from street side) it is a single brick wall, but it already has earth the other side from the other property, but it will also need consideration.

Temp Posted February 3, 2020 Share Posted February 3, 2020 Check the max height before ordering. Some makes are aimed at DIY and have limits of around 2ft/600mm. I've seen some places say anything over a meter should be "designed" specifically so i suppose your BCO may want to see input from an SE but perhaps not. I think if you can show him a brochure saying it's ok to use at that height then he should be ok. Link to comment Share on other sites More sharing options...
Declan52 Posted February 3, 2020 Share Posted February 3, 2020 What do you want it to look like?? Brick, plastered, stone or other. This choice will push you down a particular method and rule out others. 1 Link to comment Share on other sites More sharing options...
Temp Posted February 3, 2020 Share Posted February 3, 2020 (edited) Google found Allen Block hollow concrete blocks can be used to 1.2m without filling them with concrete.. https://www.colinwell.com/media/1166/colinwell-allan-block-retaining-wall-system-brochure.pdf PS making the wall/steps curved would probably make them stronger.

Declan52 Posted February 3, 2020 Share Posted February 3, 2020 I used these blocks for mine. They require no concrete base, a 200mm depth of well compacted hardcore is all mine sits on. They are as DIY as a retaining wall comes. https://ag.uk.com/retaining-wall/anchor-diamond/ Link to comment Share on other sites More sharing options...
Declan52 Posted February 3, 2020 Share Posted February 3, 2020 I have 2 different size blocks in my walls. The largest can go to 1.2m without any membrane but can go higher if needed using one. The smaller blocks can go to 0.9m and that's it. 2 Link to comment Share on other sites More sharing options...
PeterW Posted February 3, 2020 Share Posted February 3, 2020 @Declan52 what was the unit price or price / m2 for those ..? Link to comment Share on other sites More sharing options...
Declan52 Posted February 3, 2020 Share Posted February 3, 2020 1 hour ago, PeterW said: @Declan52 what was the unit price or price / m2 for those ..? I think the larger block holding the driveway back was £25 sqm and the smaller £15sqm. But I got a very good deal as I also bought a lot of their paving blocks as well at the same time and I used the same company for my thermal blocks so had bought maybe £10k worth of materials from them. And that was 5 years ago and they are a local company to me. Link to comment Share on other sites More sharing options...
Temp Posted February 3, 2020 Share Posted February 3, 2020 Those look good @Declan52 I think your photos show off the blocks better than some of theirs. Link to comment Share on other sites More sharing options...
