Hi
I need to install 7 fence posts, I want to do them AS FAST AS POSSIBLE!


Regardless of how you dig the holes if you want a quick job fill them in
with quick setting postcrete or similar. It comes ready mixed in bags from
your favourite builders merchant. Mixing normal concrete is cheaper, but
takes a lot more time to set.
In my experience a small hole is only best in solid ground. In soft sandy
soils a bigger hole and more postcrete/concrete is more stable.
