RSM Lining Supplies hosted its sixth biennial Open Day on 4th September 2025, welcoming customers, partners, and exhibitors to its headquarters despite challenging weather conditions. The event once again confirmed its status as a key fixture in the sewer rehabilitation industry calendar.
The Open Day combined technical presentations, live demonstrations, and new product launches with valuable opportunities for networking and hospitality. Beyond the serious business of trenchless technology, guests also enjoyed RSM’s trademark entertainment, including evening performances from BBC Radio One’s James Cusack and the legendary Judge Jules. This blend of industry insight and customer appreciation reflects the company’s ethos: combining technical excellence with strong, long-term partnerships.
Milestones since 2023
The event also served as a platform to reflect on RSM’s achievements since the last Open Day in 2023. In just two years, the company has processed more than 80 kilometres of liner through its impregnation service, manufactured and dispatched over 93,500 Pipe Aid Kits, and supplied more than 42 kilometres of UV liner. Training has also been a major focus, with 370 engineers completing RSM’s certified course.
In the past 12 months alone, the business has provided products and services to 736 customers in 27 countries, a measure of its growth and reputation as a global solutions provider in pipeline rehabilitation.
Product launches and technical innovations
Visitors to the 2025 Open Day had the opportunity to see several major new products first-hand. Among them was an enhanced UV LED curing cable for the Sewertronics SpeedyLight+ system, designed to reduce kinking and improve usability, particularly in demanding site conditions.
The launch of the Gecko E Lateral and Gecko E Power Cutters also attracted attention. Compact and electrically powered, these cutters are tailored to the increasing demand for low-emission, battery-capable equipment in urban projects where access, noise, and environmental restrictions are critical.
Finally, RSM introduced its WRc-approved Manhole Spray Lining System, which applies the GeoKrete Geopolymer to create a long-lasting, corrosion-resistant barrier for manhole rehabilitation. Together, these launches underscored RSM’s commitment to delivering complete, integrated systems that address the real challenges faced by contractors.
Live rehabilitation demonstration
One of the highlights of the day was a comprehensive live rehabilitation sequence, showing how RSM’s technologies perform when used in combination. The process began with the inversion of a liner pre-impregnated with CP655 Class 1 Epoxy Resin, installed using a KrasoTech Sluice 300. Curing was then carried out with the KrasoTherm Hybrid Boiler, with progress monitored in real time via the VeriCure system.
Attendees watched as the Gecko E Lateral Cutter reinstated laterals with speed and precision, before connections were sealed using a Top Hat System to ensure watertight joints. The sequence continued with UV LED curing of the lateral liner using the upgraded Sewertronics SpeedyLight+, and concluded with manhole rehabilitation, where the Spray Lining System applied GeoKrete Geopolymer for durable, long-term protection.
This step-by-step demonstration highlighted the efficiency, reliability, and environmental benefits of RSM’s integrated solutions, leaving visitors with a clear impression of how the systems can perform together on site.
Collaboration across the supply chain
The Open Day also celebrated collaboration across the trenchless supply chain. RSM partners — including Applied Felts, BKP Berolina, Dancutter, KrasoTech, Picote Solutions, Sewertronics, UKSTT, Vortex, VP Polymers, Westrade Group, and WRc Group — supported the event, sharing insights and innovations.
This collective presence underlined the importance of partnerships in advancing trenchless technologies, from developing new materials and systems to ensuring contractors have the training and technical support they need on site.
Looking ahead
Managing Director Richard Davis reflected on the event’s success:
“The Open Day was a true reflection of the teamwork, innovation, and commitment that drives RSM. I could not be prouder of how far we’ve come, and I want to thank our customers for their loyalty and support. Without them, none of this would be possible.”
Looking forward, RSM will continue to drive innovation in pipeline rehabilitation, invest in training and support, and build partnerships across the sector. With the next Open Day already confirmed for 2027, the company remains committed to leading through innovation and collaboration in trenchless technology.
