FINISHING THE INFILL
The procedure below applies to all tanks irrespective of operating mode.
After filling in with concrete, apply the infill material in layers of 15/20 cm, first filling the tank with water and then
filling in with lean or lightweight concrete up to a depth above the maximum level reached by the groundwater.
The infill material must be liquid so that it covers the entire outer surface of the tank, up to the top level of the tank
cover.
To conclude, add a layer of washed round gravel and sand to completely cover the tank.
