ultramods Posted June 11, 2019 Posted June 11, 2019 Can someone tell me roughly how much a 28 metre long, 900 mm high (above ground) blockwork garden wall should cost using either Solid Dense 7.3N 140mm or 100mm concrete blocks please? The wall is single skin, no render or coping required.
Carrerahill Posted June 11, 2019 Posted June 11, 2019 (edited) 25.2m^2. 252 x 100mm Blocks @ 85-90p = £226.80 (maybe £252 for 140's) £1 a block laid £252 Some brickies will want £2 a block (go jump) and some will take less - my brickie was £300 for 400 blocks laid absolutely perfectly! £478.80 Edited June 11, 2019 by Carrerahill 1
Construction Channel Posted June 11, 2019 Posted June 11, 2019 What's it being laid on and what's it for?

I have been quoted £3k by the builder that has done all the other building work for the house but thought it sounded quite expensive. The wall will be retaining wall, so not sure if that means blocks would need to be laid flat or not

ultramods Posted June 11, 2019 Author Posted June 11, 2019 (edited) The wall would be at the front of the house in this photo, so that the lawn is the same level as the house floor. the wall would be at its highest of 800mm to the left of the photo and maybe only 400-500mm to the right hand side.

scottishjohn Posted June 11, 2019 Posted June 11, 2019 is the ground behind it flat or does it go up at an angle --and what angle?

The wall is single skin, no render or coping required. OK - attempt No. 2! You will need at a minimum 140mm block with piers every 2-3m - so worst case 252 blocks for basic wall plus about another 120 block for 14 piers so £372 for block - £372 laid ton of sand and 10 cement £80-100. Found - digging this will be the biggest cost - £1000.00 - £200-500 for a concrete depending on hand mix or trucked in. I think 3K sounds fair actually. £1500 will be materials. 3-5 days work. 1

scottishjohn Posted June 11, 2019 Posted June 11, 2019 maybe a rough cross sectional drawing would help

As far as @ultramods was concerned it was a wall in a garden. Fair assumption unless you know what the retaining part changes in the construction

Going off the point, but the build is looking good! 1
K78 Posted June 11, 2019 Posted June 11, 2019 (edited) Cheapest way to do this is concrete Lego blocks. They have capping stones for the top. I done the same on a much bigger scale. Don’t need a SE design or foundation at your height if the ground is adequate. Digging could be done in a day with a digger n driver (£150). Edited June 11, 2019 by K78 1

scottishjohn Posted June 11, 2019 Posted June 11, 2019 (edited) or something that looks pretty like marshalls dry stacking walling --do it yourself in no time https://www.marshalls.co.uk/homeowners/view-croft-stone-garden-walling the layer above sits behind the lower layer so it locks together i have used it ,water drains out through the gaps as well so no worry about a tsunami of mud Edited June 11, 2019 by scottishjohn 1
