Job prerequisites were to remove the old deck as it was a potential liability. Design and build a functional and aesthetic structure. Clean access around the side of the house and a fence with gates for security.
We had a lot of concrete to cut and break up with jackhammers. This could only be done effectively by machine. There was about 20 cubic metres of concrete to remove, aged and reinforced.
We encountered reactive soil of a type that I had never come across before. See the video below.
The solution was to dig it out and fill up the hole with crusher dust, about 8 cubic metres altogether.
We decided to colour the concrete a charcoal colour to highlight the plant and timber colours.
