By Trenchless Technology Staff June 8, 2026

Since its founding in 2003, RSM Lining Supplies has grown to become one of the world’s largest suppliers of cured-in-place pipe (CIPP).

That reach, portfolio of rehabilitation products and team now fall under the auspices of Azuria Water Solutions, a leader in technology-enabled water solutions. On June 8, Azuria made the announcement of its acquisition of RSM Lining Supplies.

Founded by Richard Davis, RSM will maintain its headquarters in the United Kingdom and its locations in Sydney and Melbourne, Australia.

Serving municipal and residential contractors, RSM’s wastewater products are used in gravity and pressure pipe applications, ranging from 50 to 2,000 mm (2 to 79 in.) in diameter and utilizing a variety of cure methods, such as steam, Ultraviolet and LED.

“This is our first European acquisition since rebranding to Azuria in 2024, and we couldn’t be more excited about the RSM team,” says Rob Tullman, Azuria president and CEO. “Combined with Insituform’s 50+ years of manufacturing CIPP liners in the UK, we’re excited to further enable RSM’s growth.”
