Suspended Slab Crack Injection — Pemulwuy, NSW

Overhead suspended slab crack injection with minimal occupant disruption

The Challenge: Extensive cracking in the suspended concrete slab system from reinforcement placement deficiencies and concrete shrinkage required immediate stabilization. Overhead crack injection on the underside of the first-floor slab presented gravity-defying technical challenges.

Our Solution: We deployed specialized overhead crack injection using low-viscosity epoxy resin engineered for upward penetration. Innovative portable injection platforms eliminated traditional scaffolding requirements, allowing elderly residents to remain comfortably in their home.

Results: The overhead injection stabilized all 40+ cracks with 100% penetration confirmed through structural testing. The portable platform approach eliminated scaffolding costs and enabled elderly residents to remain in their home throughout the 2-day timeline.
