CASE STUDIES
Cappagh's rehabilitating success with SAERTEX-LINER and Starlight UV System
Cappagh Group's lining division recently undertook a challenging project in Swindon, involving the rehabilitation of three lengths totalling 180 meters of badly deformed 300mm pipes. The location posed significant challenges, situated in a narrow alley bordered by properties on both sides, making access and manoeuvrability challenging.
The project required extensive cleaning of
each length of pipe, which also had the presence of multiple protruding connections that needed to be cut back and reopened once lined. The installation method selected was UV, utilising the Trelleborg Starlight UV Lining System to cure a SAERTEX-LINER® MULTI Type S+.
Recognizing the importance of expertise in ensuring successful project execution, the lining team from Cappagh Group underwent comprehensive installer training provided by SAERTEX multiCom®, which included technical knowledge and hands-on practice. As a result, six members of their team are now certified SAERTEX LINER installers.
S1E Ltd supported Cappagh Group by sourcing the necessary liner from SAERTEX multiCom®, providing the Starlight UV system on hire, and S1E’s CIPP Lining Development Manager, Dave McCarthy offering on-site assistance throughout the project. The UV installation method, coupled with the Starlight system, provided an efficient and effective solution for curing the SAERTEX-LINER®
SAERTEX-LINER® MULTI Type S+ from SAERTEX multiCom is a state-of-the-art glass-fibre reinforced liner designed for trenchless pipe rehabilitation. Its key benefits include:
■ High durability and strength: Made from high-quality materials, the liner
offers exceptional durability and longevity with a technical service life of up to 100 years whilst maintaining low wall thicknesses. It is also resistant to the hydrogen sulphide (H2S) attack of normal domestic wastewater, which is typically causing corrosion in concrete pipes.
■ Installation-friendly construction: The liner is supplied pre-impregnated with a
long shelf life. The product properties allow high pull-in forces and easy handling even in challenging and confined environments.
■ Smooth inner surface: The smooth inner surface of the liner facilitates efficient

flow within the rehabilitated pipe, reducing friction and improving flow performance.
This challenging rehabilitation project demonstrates the efficiency of the UV installation method and the Starlight’s compact design which made it easier to manoeuvre the unit, with only a compressor also required on site. The Starlight UV Lining System from Trelleborg (former I.S.T.) is a cutting-edge technology used for curing liners of up to 90m in length with a 4 x 400 W light chain and is especially designed for hard-to-reach places. Its other benefits also include rapid cure times to reduce installation time, uniform curing performance, and being an environmentally friendly option for pipe rehabilitation
