Liam arrived with the Lambert Cavalry today and brought along a micro digger for support! The reason for the cavalry was that we discovered we would need to dig down a total of 45cms from the finished floor height to allow us to put in all the required sub-floor to meet building regulations. The concrete removal made up about 15-20cm of this, and with a 100sq metres to cover, digging the clay/soil out was going to be impossible with spades.
In reality after starting we discovered that we needed to dig down deeper in places to reach something firm upon which we could start to put hard core back in!
I must confess I started to have real doubts about my sanity watching a digger drive around the inside of my house myself and others wheel barrowed out hundreds and hundreds of barrows of heavy clay and soil. It is really totally surreal.
