Granny Flat Drainage and Concrete Levels for Cooloongup Properties

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

Supplied engineering should be reviewed against the actual site levels, access and service locations before the concrete booking is confirmed.

Concrete thickness, strength and reinforcement should follow the supplied engineering or building specification.

External paths and patios should direct water away from buildings without creating low points or unsafe transitions.

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.
