Hygienic FRP Lining for Potable Water Storage Tanks
SGI Composites was appointed to carry out a permanent repair to a hospital potable water storage tank, restoring its integrity with a high-performance fibreglass (FRP) lining system. Designed to create a seamless, watertight barrier, the lining protects against leaks, corrosion, and contamination, ensuring the tank remains safe and compliant for potable water storage.
The entire installation was completed within one week, minimising disruption to critical hospital operations. The refurbished tank now provides a durable, long-term solution, delivering reliable performance and peace of mind for years to come.

Completed FRP Lining System
The fibreglass (FRP) lining system has been successfully completed, creating a seamless, waterproof seal across the entire interior of the tank. This durable lining ensures long-term protection against leaks, corrosion, and contamination, making the tank safe and reliable for continued use.
Resin Wash Finish
The potable water storage tank has been finished with a specialist resin wash, providing a smooth, hygienic, and fully sealed surface. This final coating enhances the durability of the FRP lining while ensuring the tank remains suitable for safe potable water storage.
Completed FRP Lining System
The potable water storage tank has been fully lined with a four-coat fibreglass (FRP) system, creating a seamless, watertight, and hygienic internal barrier. This multi-layered approach ensures enhanced durability, chemical resistance, and long-term protection, making the tank fully suitable for safe potable water storage.
