Zetland Surelock System Installation

Innovative Surelock temporary moving joint system installation

The Challenge

This commercial property required specialized temporary moving joint installation using the advanced Surelock system to accommodate up to 25mm differential settlement during adjacent excavation works. Traditional rigid joint systems couldn't accommodate the predicted movement magnitude while permanent expansion joints would compromise future structural integrity. Timeline constraints required immediate installation before excavation commenced in 2 weeks. The occupied commercial building demanded methods maintaining business operations for 15 tenants generating $500,000+ annual rental income. Installation precision of ±2mm tolerance demanded specialized expertise rarely available in Australia.

Our Solution

We deployed specialized Surelock installation utilizing precision-engineered components and certified methodology. Comprehensive manufacturer training ensured full compliance with system specifications and warranty requirements. Precise structural surveys established exact joint locations, followed by diamond core drilling creating perfectly aligned anchorage points meeting ±2mm tolerance. Custom-fabricated Surelock assemblies were installed using specialized torque equipment ensuring optimal pre-load on sliding mechanisms. Single-day installation minimized business disruption. Comprehensive movement monitoring equipment integrated with each assembly provided real-time tracking throughout excavation.

Results

The Surelock system successfully accommodated 22mm of differential settlement during the 8-month adjacent excavation period, performing within engineered specifications and preventing any structural damage. Real-time monitoring confirmed system performance throughout. Zero tenant disruptions occurred, protecting $500,000+ in annual rental income. Precision installation met all manufacturer warranty requirements, securing comprehensive 10-year coverage. Following excavation completion, the system was successfully removed and joints permanently sealed, restoring original structural continuity. The $85,000 temporary system saved significantly versus the $200,000+ permanent expansion joint alternative. The project established TRD as Australia's first certified Surelock installer.
