Digging through rock

[petit_pablo]

Im putting a retaining wall in the back garden but the garden has alot of chalky rock about 6" under the soil and i need to remove alot of it. My pick just bounces off it!

What would i be best hiring to dig it out? I also need to put fence posts down into it?!

kango with a clay spade will go through it fairly easily. as will a sharp shovel.

just to check...

you aren't digging out chalk so you can fill the trench with concrete, are you?

Its not pure chalk but also no trench, just post holes
