CASE STUDY: ChemGrout CG-570 Concrete & Grout Remediation
Project Background
O-I Glass, a leading global manufacturer of glassware since 1903, approached CGS to assist it with concrete and grout remediation works required at its major production facility in Sydney’s western suburbs. The Sydney plant underwent a significant shutdown to carry out scheduled maintenance on a 55-metre concrete chimney stack.
Project Objective: Reliable and Precise Chimney Grouting
Specialist refractory contractor BEROA was engaged to deliver a high-quality concrete & grout remediation solution. The scope of works included the use of scaffolding, abseilers and the installation of custom-manufactured stainless steel interlocking sleeves. These interlocking sleeves encased the damaged concrete structure and were injected with Conbextra HS—a high-flow, high-strength, shrinkage-compensated cementitious grout.
CGS Equipment’s Concrete & Grout Remediation Solution
To meet the unique requirements of this high-elevation application, CGS Equipment supplied the ChemGrout CG570. This powerful pump was selected for its ability to deliver high torque and reliably pump grout, containing 1mm aggregates, over 55 metres vertically through a 1″ hoseabseilers, .
Over the course of approximately 1 hour, the CG570 successfully pumped more than 1.8 cubic metres of grout to the top of the chimney. From there, abseilers injected the material directly into the interlocking stainless steel sleeves.
The full remediation project—including preparation, grouting, and installation—was completed within 11 weeks. The efficiency and reliability of the ChemGrout CG570 played a critical role in meeting this tight deadline.
