EARTHWORKS:
1. Prepare the existing foundation below by removal of any top-soil
containing organic matter which could inhibit compaction
2. Proof roll the foundation and remove and reconstruct areas that
break up or show evidence of movement under proof loading. 1 1
3. Sand filling under slabs or footings shall be placed in 200mm
max layers, (Uncompacted), Compacted in accordance with AS1289 - -

4. Fill material other than sand (ie gravel, decomposed rock or
broken rock, free from organic material and lumps of clay) under
slabs or footings to be compacted to achieve an density ratio MH

TANKS:
It is recommended that underground tanks comply with the following:
1. Screens with the following characteristics to be provided to cover each orifice outlet: 1000 1000
a) For orifices up to 150Ø, a fine aperture-expanded metal mesh screen (BHP
Maximesh RH3030 or equivalent) with a minimum area of 50 times the area B.L. B.L.
of the orifice. For larger diameter orifices, a courser grid mesh with a
minimum area 20 times the orifice area may be used as an alternative.
b) Steel screens to be stainless steel or hot-dipped galvanized.
c) Where aperture-expanded mesh screens are employed, they must be
positioned so that the oval shaped holes are horizontal, with the protruding
lip angled upwards & facing downstream. A handle may be fitted to ensure
correct orientation & easy removal for maintenance.
d) Screens to be located so that they are at least 1.5 times the orifice diameter
=
or 200mm from the orifice plate, whichever is the greater.
e) Screens to be placed no flatter than 45° to the horizontal in shallow
storages up to 600mm deep. In deeper or more remote locations, the
minimum angle should be 60° to the horizontal.
