Applus+ in the UAE completes emergency pipeline repair with PRIMUS liner technology

The project required urgent mobilisation and a trenchless solution that could meet strict municipal regulations and environmental standards. Applus+ engaged PRIMUS to deploy their advanced liner technology, enabling internal rehabilitation of the pipeline without the need for full excavation.

The repair utilised a custom-fabricated aramid-reinforced liner, engineered to accommodate the pipeline's operational pressure of up to 20 bar. The system was installed using a pull-in method, without curing or chemical bonding, ensuring clean, safe reinstatement of potable water flow.

 "The installation was a great success," said Mark Loughman, Head of Water Infrastructure Services at Applus+. "This was a truly collaborative effort. I want to extend my gratitude to our operations team for their outstanding work under pressure, and to Simon Compton for his continued support throughout the project.”

Project Highlights

Precision Engineering

• Custom liner designed to exact specifications of the pipe profile
• Maintained flexibility for thermal expansion and seismic activity

Efficient Execution

• Installation footprint restricted to localized excavations at entry and exit points
• Rapid installation at speeds up to 10 metres per minute reduced overall downtime

Quality & Compliance

• Liner underwent full factory testing and QA/QC before deployment
• No on-site curing process required, reducing health, safety, and environmental risks
• Fully compliant with potable water standards

Sustainable & Cost-Effective

• Reduced excavation volume minimized impact to roads and local infrastructure
• Limited need for heavy machinery cut down on emissions and noise pollution
• 50+ year design life ensures long-term value with minimal maintenance

This emergency project restored full pipeline functionality within a critical timeframe and demonstrated the strength of Applus+ rapid-response capabilities and its commitment to deploying innovative, low-impact solutions. Working closely with PRIMUS, the team delivered a safe, efficient, and sustainable repair—reinforcing Applus+ as a trusted partner in water infrastructure integrity.
