Hi
Just a quick question if anyone has the time to answer
How many 25kg bags of ballast/cement to mix 1 cubic metre of concrete?
Assuming a mix of 4:1 ballast:concrete
I'm laying a base for a greenhouse and need about 3 cubic metres of
concrete but I need to know how many bags of ballast/cement to order.
I would have ordered in ready-mix but its just too far away from the
drive to barrow/pump.
Many thanks in advance

3 Cubic Metres?

THREE?

That is one hell of a lot of concrete. Me thinks you have something wrong
there.

The greenhouse is going to sit on a 2' wall to protect from potential
flooding. This years rains put the bottom of my garden in 6 inch of
water.

How do you get in without the water getting in?

Or are you going to allow the water to get in, but everything is going to be
on staging?

Mike
