| After many years of
use, the supporting corner posts of the compost bins were becoming
unstable caused by rotting within the ground. It was therefore necessary
to remove any remaining compost and demolish the old compost bins.
Fortunately the mill had been donated a number of 8ft long concrete
posts that could be used for constructing the new compost bins. As the
bins were to be only 5ft high, the same height as the original bins, it
was necessary to create 3ft deep holes in which to insert the concrete
posts. Once the first post had been inserted into the hole, it was
checked for vertical alignment. |
