Wungong Granny Flat Construction – Granny Flat Concrete Extensions and Infill

Granny flat concrete needs to be coordinated with the building plans, engineering, services and access. In Wungong, Santa Concrete can assess small extensions, porch slabs, laundry infills, service penetrations and connecting concrete.

The work can include set-out, excavation, spoil removal, road base, compaction, formwork, reinforcement, concrete placement and finishing.

Any changes to the dwelling size, wall layout or engineering can affect concrete quantities and the construction scope.

Drainage pits, strip drains and service trenches should be located before the final formwork is fixed.

The builder, engineer and service trades should provide clear set-out and penetration details before the pour.

The project should be planned around existing slab levels, tie-ins, service locations, saw cuts and staged construction. Changes to plans or engineering should be reviewed before concrete quantities are finalised.

Pricing is more accurate when engineering, earthworks, pump access, service penetrations and external concrete are clearly identified.
