How much concrete do I need?

ottosump · 8 Jul 2020

Hi group, can anyone tell me approximately how much concrete I should order for the planned driveway pictures, please ignore the 2.5m section detailed on the right, that has now been taken out.
Thank you..

Depends how deep but looks to be about 2 cubic meters

1.5 cube at 100mm thick.

Really, is that all, I thought it was going to be about 2.5m at 4 inch

Sounds right I calculated based on 150mm

Thanks guys, I worked the area out at approx 13.4 square metres

It's only 1.8 cube if you square off the rectangle i.e. 5.12m x 3.64m x 0.1. Then you have to remove the triangle which brings it down to 1.5 cube.

Don't "order" an amount, use a barrow mix company and try to find one with a low minimum order amount. 1.5m is barely worth them starting up the lorry for but at least you'll only pay for exactly what you need.

Ordered 1.5m, used approx 1.2m on the drive, we did bulk it out with old bricks and re-bar though, used what was left over on my own property, luckily I,d shuttered an area of anticipating ordering too much so none wasted. Was £216 delivered and the crete had fibres in it, never used that before.
Thanks everyone for the advice, much appreciated.
