INSTALLATION
1. EXCAVATE A HOLE & LAY CONCRETE BED
Approximate dimensions

For DRY CONDITIONS excavate a hole to appropriate depth allowing minimum clearance on all sides and
base of the unit of 200mm and level the base.

For WET CONDITIONS excavate a hole at least 300mm deeper than the tank, for lean mix concrete and hard-
core base. Allow for tank width plus at least 400mm with additional allowance for any necessary shuttering.
De-water the excavation using suitable pumping equipment. Ensure that the pump discharge does not
saturate the ground in the immediate vicinity. The installer should ensure that the base is adequate to
support the weight of the tank and its contents. Place a sheet of polythene over the hard-core and up the
sides of the excavation before putting in the concrete cradle.

For UNSTABLE BASE of the excavation, i.e. running sand or similar, excavate an additional 250-300mm below
concrete levels and fill up with compacted hard-core.

A base of at least 150 - 200mm of lean mix concrete should be provided. (FOR CONCRETE SPEC. SEE BELOW).

It is recommended to back fill with C25 SEMI-DRY MIX
