Underpinning

UNDERPINNING in SYDNEY


In construction, underpinning is the process of strengthening and stabilising the foundation of an existing structure.

Underpinning may be essential to provide the extra foundation support required to withstand amplified loading, to stop ongoing settlement, to underpin existing shallow foundations prior to adjacent new construction, and for seismic retrofit.

Pillar Building Services offers supplementary support to foundations that are incapable to safely support current or planned loads.

Common Uses:

• Improve weak underlying soils
• Underpin with deep foundation elements
• Treat expansive or collapsible soils.
