Mass concrete underpinning in Melbourne is the traditional, proven method: excavating beneath the existing footing in controlled sections and filling each with concrete down to firm ground. It has held homes level for over a century, and for most standard footings on reachable stable soil it is the most reliable and economical choice.
It is straightforward, load-tested and permanent. We assess the depth to firm ground first, then quote a fixed price per pier.
What is mass concrete underpinning?
It is the extension of a footing downward using concrete poured in sequenced sections. Each section is dug, cast against firm ground and allowed to cure before the next is opened, so the house is never left unsupported. The result is a deeper, wider footing bearing on stable soil.
How the process works
We work in a hit-and-miss sequence, opening small sections beneath the footing in a planned order. Each pit is dug to firm ground, the base is prepared, and concrete is poured and pinned to the existing footing. Once cured, the next section in the sequence is opened, until the whole footing is supported on new mass concrete.
When it is the right method (and when it is not)
Mass concrete suits homes where firm ground is within reach and access allows hand excavation, which covers a large share of Melbourne. Where stable ground is very deep or the soil is soft, screw pile underpinning reaches further, and for minor lifts on slabs, resin injection underpinning may be enough. We match the method to your ground.
Cost of mass concrete underpinning
As an indicative Melbourne range, mass concrete underpinning costs around $1,500 to $3,000 per pier, with depth to firm ground the main variable. Compare it against the other methods in our underpinning cost guide.
