iLine works closely with the UK highways sector and has rehabilitated hundreds of kilometres of gravity sewers, pipes and culverts beneath and alongside the UK’s highways. iLine installs EnviroCIPP UV cured CIPP lining, rigid GRP segmental lining and patch lining to rehabilitate and extend the life of gravity sewers, pipes and culverts. iLine provides full scheme design as part of its service. iLine offers many advantages to the UK highways sector including speed of installation, low environmental impact, minimal or even zero impact on traffic flows as well as a fully structural repair solution.

Line’s EnviroCIPP is a fully structural GRP liner offering modulus values up to 21,000 Mpa. Where existing water pipes and sewers have failed structurally, EnviroCIPP provides a completely new structural liner which is, essentially, a new pipe hosted within the existing failed pipe. EnviroCIPP is available in diameters from 150mm to 1500mm. EnviroCIPP’s UV curing system provides a quick and quiet installation process, reducing noise, disruption and time on site. Most importantly, water pipes can be returned to service quickly. EnviroCIPP uses proven technology with thousands of kilometres installed worldwide and has a design life of 125 years. It outperforms needle felt liners offering higher flexural strength, water tightness and elasticity properties.

For larger diameter and non circular gravity pipes and sewers iLine’s Segmental Liner system provides a simple and cost-effective solution. Liner segments are designed and tailor-made for the failed host pipe. They can be made to fit circular and non-circular profiles including rectangular, square, egg shaped and oval. One of the benefits is that they can be made in large diameters up to 7000mm.

Where a small section of pipe, gravity sewer or drain needs localised repair, patch lining provides a cost effective and quick long term fix. Patch lining offers many advantages including easy site access, maintenance of existing flows and lower cost than larger repairs. The process can be used in any location where you can get access to one end of the pipe, such as under roads, railways, canals, and pipes that are too deep to excavate on.
