The Rainwater Tank
We're having an in-ground rainwater tank and shed installed in our back yard. The tank will hold over 50,000 litres, and the 6m X 7m shed will actually be installed on it's roof. Here's some progress photos.
Pouring the Roof and Slab
Once the walls are completed, the four support columns are formed up, and plastic/reinforcing laid down for the tank roof. We are pouring the roof as a 6x7 metre slab, and installing the new shed on top of this.
To hold the roof up while the concrete is setting, temporary steel plates shaped like pie wedges are used.
Spraying in the Walls
The walls are sprayed on with a concrete pump. This is done in multiple stages. The first stage, or layer, is around 50mm thick. Galvanised reinforcing is then wired in, and then subsequent layers sprayed over the top of that, to a thickness of 130mm.
Pouring the Floor
The mesh, which forms the outside of the tank wall, has been plastered with concrete. With the floor reinforcing laid, we're almost ready for the floor to be poured - just some reinforcing starters for the 4 support columns.
The Outside Shell
When the excavation is finished, the bottom is compacted and a layer of rubble put down, in readiness for the concrete base to be poured.
The reinforcing and mesh in these photos will be plastered with concrete to form the outside shell of the tank.
The Hole
It's actually a 70 cubic metre cylinder in the ground. The edges need to be as parallel or vertical as possible - the better the hole, the easier the walls and job will go
