Sunken concrete slabs can indicate compromised sub-soils. If you notice uneven, cracked, or “pumping” slabs, it’s crucial to address the issue promptly with sinking foundation repair. Let the experts at Underpinning assess the situation, scope the necessary work, and re-level your slabs to prevent future damage to your foundations and property by stabilising the soil beneath.
Welcome to Underpinning, your trusted partner for repairing sinking foundations in Brisbane and the Gold Coast.

Several factors can cause subsidence, leading to sunken or cracked concrete:
Subsidence is often visible and can manifest in various ways:
Drilling a series of tiny holes in the affected area.
Introducing our specially formulated polyurethane resin.
The resin fills voids and hardens instantly, compacting the ground. The area is reinforced and re-levelled if required.
