Retaining wall

[michaelthegardener]

im wanting to build a 8m long 600 high going to use blocks laid flat but im unsure on the depth and width i need for the footings ive been quoted 650 to have this done as well as the drive for 2750 ( ive allready got the blocks) 40 square meters but while the price for the drive seams ok 650 for the wall seams low to me but to be honest ive not got a clue !

As a rough guide to footing width, you want, as a minimum, width of wall + 100mm to each side.

So, a 25mm (double skin) brick wall would need a footing of...

100 + 225 + 100 = 425mm. which we would typically excavate at 450mm width minimum.

8m wall @ 600mm height (is this overall haight or height above ground?) - 4.8m²

4.8m² of wall for 650 quid equates to 135 quid/m² which a little bit on the cheap side, but it all very much depends on where you are in the country, what brick/block is to be used, and what the site access is like.
