CASE STUDY
AIRPORT OFFICE BLOCK - REGIONAL VIC

PROJECT OVERVIEW

The office block at a regional Victoria airport faced a significant challenge as an initial survey and scope of works revealed a building foundation subsidence of +30mm. It was imperative to address this issue while minimising asset downtime and avoiding disruptions.

SCOPE OF WORK

The scope of work involved a meticulous investigation and survey of the office block. The selected solution was HMI RR40 polyurethane resin, to be injected under the foundation at depths of up to 2000mm, depending on the quality of the bearing strata. Achieving an aesthetically pleasing result required the closure and re-sealing of articulation joints in the brickwork, with a strict +-2mm tolerance set as the success criteria. The goal was to minimize asset downtime, targeting a reduction of -8 hours.

PROPOSED SOLUTION

Slab Jack Industries proposed the use of HMI RR40 polyurethane resin for the injection under the foundation. This approach was chosen for its efficacy in addressing subsidence issues. To meet aesthetic standards, the articulation joints in the brickwork would be closed and re-sealed, ensuring a precise +-2mm tolerance. The proposed solution aimed to achieve these objectives while minimizing asset downtime, with a targeted reduction of -8 hours.

OUTCOME

Upon completion of the project, the office block met the required tolerances, and the articulation joints were successfully closed and sealed. Comprehensive testing of all services, including gas, water, greywater, and black water, was conducted, confirming their functionality. The office block was seamlessly returned to full operational service, surpassing expectations with an asset downtime of only 6 hours.
