dont tell the builder, just show up with a sledgie and start battering the slabs.

you could also run an overhead with a steel support cable, i imagine theres going to be an argument when you ask him to lift all the slabs.

why cant you just drive an earth spike into the ground with a decent CPC? seems easier than lifting 35metres worth of slabs and digging a trench

Whether he digs a new trench or employs TT, the main thing is that he is no longer relying on the armour.
