St James Granny Flat Construction – Granny Flat Earthworks and Site Preparation

Granny flat concrete needs to be coordinated with the building plans, engineering, services and access. In St James, Santa Concrete can assess site cuts, soil removal, levelling, road base, compaction and slab preparation.

Depending on the plans, the scope may include edge beams, thickened areas, footings, service penetrations and nominated slab steps.

The slab platform depends on suitable support, consistent compaction and correct levels beneath the concrete.

Falls and drainage should be coordinated around the granny flat, existing home, patios, paths and surrounding ground.

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

The project should be planned around bobcat access, excavation depth, spoil disposal, compaction and final platform levels. Changes to plans or engineering should be reviewed before concrete quantities are finalised.

For an initial assessment, send plans together with photos of gates, side access, the backyard, existing structures and drainage points.
