Pouring Conccrete into the columnsThis is another entirely manual process whereby concrete is mixed in the concrete mixer by hand as described previously and then delivered by wheelbarrow before being lifted in small buckets passed hand to hand to the guy standing on the platfom who then tips it into the column formwork. This was an all day job to complete the 18 columns. Concrete volume circa 2.25 cubic meters.chiyman (0 votes)
