What Is Structural Underpinning?
Cracked walls, uneven floors and doors that no longer align to their frames are all signs that the foundation of a house may have sagged due to unstable soil beneath the structure. Underpinning concrete footings is a means of propping up and strengthening the foundation so the structural damage of the home is repaired, and further damage avoided.
Structural underpinning involves excavating the original footings, then pouring more concrete underneath the footings and reinforcing it with steel to give additional strength. Once the concrete has cured – which typically takes around five days – heavy duty jacks are placed on the reinforced concrete and the whole structure is jacked up, which closes up the cracks and voids. Once the cracks have been successfully closed up, either heavy duty props are positioned to stop the building from sagging again, or the jacks are left in place and more concrete and steel reinforcement is used to make the repairs permanent and strong.

Hydro Vacuum Excavation
Using specialist Hydro Vacuum Excavation Technology, we offer the fastest and cleanest underpinning method available in Australia.
As an alternative to mechanical excavation, hydro excavation uses high pressure water to break up soil and other material to create the excavated space. This non-destructive digging technique significantly reduces both safety risks and the chance of damage to any underground assets.
Perfect for the following situations –
- Block Method: Creates space for a 1m x 1m x 1.8m deep underpinning pad; or
- Bored Method: 4m deep x 450mm diameter cavity.
Hydro Vacuum Excavation is suitable for both commercial and industrial projects and is ideal in situations where restricted access precludes the use of traditional excavation machinery.
In addition to excavation for underpinning, this method is suitable for bunker, cellar and swimming pool excavation projects.
We’re also licensed to provide trenching services.
