Phase one of a drainage project/patio install.
The patio will be coming next year, for now they want to fix their down-spouts, re-grade the back in order to help with water issues in the basement.
First was to remove the old patio. The previous owner installed it and did a horrible job grade wise. He had the water running back towards the house and basically used what little soil for digging to fill around it. Basically it was sitting on top of the grade.
They did build it strong though. Big aggregate and also wire-mesh re-enforcement, so needless to say it wasn't very easy to take out. Normally I can lift the old concrete and break it with a sledge hammer, but that wasn't working. I ended up having to rent a jack-hammer to break it up into manageable pieces for the mini.
