Soil Test & Footing Report SCG 30002(S)

Floor Slab Details

The thickness and reinforcement for slabs on ground are shown on the structural plans.

Ground slabs may require thickenings or stiffening beams incorporated in their construction. It may be
advantageous to excavate them at the same time as the perimeter footings. Refer to the structural plans for the
locations and extent of these.

Where the stiffening beams intersect a perimeter footing, their base must be graded down to the footing base
level, 3 x N12 bars must be cogged into the footing and lapped 500 with the beams trench mesh. Refer to the
structural plans for details.

Where the stiffening beams intersect a blockbase or retaining wall, 3-N12 bars must be dowelled 150mm into the
blockbase and lapped 500 with the beams trench mesh. Refer to the structural plans for details.

A levelling layer under the ground floor slab is to comprise of granular material such as clean sand or crusher
dust compacted in 150mm layers. Either well graded sand or crusher dust can be used.

An approved polyethylene damp proof membrane of 0.2mm (min) thickness is to be placed over the levelling
layer. Laps are to be a minimum of 200mm and be taped. All service penetrations and punctures are to be fully
taped. The membrane is to be extended down the inside face of the perimeter footings and must continue under
any thickenings or stiffening beams.

Drilled Piers Supporting the Slab

Slab piers are required where there is more than 300mm of uncontrolled fill beneath the slab. They are to be
founded at a minimum of 300mm into the NATURAL MEDIUM DENSE SILTY SAND. Special attention must be paid
to the extra slab thickening required over slab piers as detailed in the structural plans.

Pad Footing Details

All pad footings must be founded to the depth nominated on the structural plans. Where this depth is not 300mm
into the NATURAL MEDIUM DENSE SILTY SAND they must be deepened down to this level.
