Henderson Secondary Dwelling Concrete – Granny Flat Drainage and Concrete Levels

Granny flat concrete needs to be coordinated with the building plans, engineering, services and access. In Henderson, Santa Concrete can assess strip drains, pits, slab falls, stormwater transitions and low-point corrections.

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

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

The finished floor level needs to work with stormwater movement, door thresholds and the relationship to the main dwelling.

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

The project should be planned around finished floor levels, water movement, nearby buildings, drainage outlets and slab transitions. 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.
