Governance & Environmental Responsibility

Consistently delivering products of the highest standard requires an investment in time, training, systems, processes and people.To ensure that Aquacrete products meet the company’s stringent quality and engineering specifications, Aquacrete operates an integrated batch control system. During production, batches are sampled on an hourly basis and stored at an on-site laboratory. A comprehensive batch numbering system is linked to the sampling system and provides a tracking and production reference.The final stage of Aquacrete’s quality management system involves laboratory testing to ensure our products comply with industry performance standards as well as the standards that Aquacrete has set for our products.All of the quality checks, lab testing and product evaluations are performed to ensure our products meet the needs of our clients.

Quality Management

Aquacrete’s structural design system is used to determine the design and installation specifications of Aquacrete structural devices.The system predicts the performance of a structural device based on the dimensions and geotechnical conditions of the specific mine site. This in turn is used to provide engineering specifications regarding product selection, product thickness and required strength for each installation site. If an installation conforms to the specifications, independent engineering certification can be obtained to confirm compliance.

Mine Mesh

Aquacrete Mine Mesh is manufactured from 4mm wire andIs hot dip galvanized. Made up of 160mm squares, mine mesh sheets provide the ideal backing surface for the application of Aquacrete shotblast solutions. Sized to suit a range of roadway dimensions, mine mesh is also suitable for a range of rib support and strata control applications.

PRODUCT FEATURES AND BENEFITS

• Smaller wire configuration provides ideal shotblast surface for Aquacrete solutions.

• Hot dip galvanized for life of mine applications. • Convenient sheet sizing 2800mm x 1125mm suitable for multiple applications.

Aquacrete’s in-situ testing technology – known as the Aquacrete Thickness Gauge – allows underground operators to non-destructively verify the thickness, and where necessary the overpressure rating compliance of structural devices.While sample coring and analysis of installed seals has provided assurance to mines, it is difficult, time-consuming and costly to carry out physical sampling and testing of every installed device. As a result, Aquacrete has developed a method for in-situ, non-destructive testing that addresses these issues. Although a new approach to testing underground structural devices, the method employs recognised testing equipment in a new application.
