Hi all, I'm after any info you have from experience of what can be achieved (volume over time) breaking bed rock.
Our plot is on the granite slabs up in Caithness.
The percolation test failed with rock at 400mm depth. Recent investigations of the water main showed that rock is 300mm deep at the front of our field. ( The main was laid in blasted trenches 800mm deep.)
So I know I'll need to rock break to install treatment plant. But I've no experience with machine attached rock breakers.
If I install a marsh shallow dig, it's still around 2.6m X 1.6m x1.6m mostly rock. So trying to get an idea of how long it will take to remove 6 cube of rock.
The figures will help decide weather to rent or purchase a breaker for a machine. With a view to selling at the end.
I've had figures of £300+v/week to rent.
Any info would be appreciated.
