Calista Granny Flat Drainage and Concrete Levels

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

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.

Existing backyard drainage problems should be discussed before excavation because the new building platform may change water flow.

The quotation should identify which contractor is responsible for approvals, surveying, engineering and service locations.

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.
