iPlus Glass Explained: UV Cured CIPP for Sewer Renewal
Sewer renewal specifications are shifting. Engineers are looking for liner systems that cure faster, produce fewer emissions on site, and deliver stronger structural performance per millimetre of wall thickness. UV-cured glass fibre CIPP addresses all three demands in a single product. Insituform manufactures iPlus Glass as part of its CIPP solutions range, engineered specifically for […]
CIPP Resin Suppliers: Key Questions Before Placing an Order
Every CIPP installation depends on the resin performing exactly as specified once it reaches the host pipe. A mismatched chemistry, inconsistent batch quality, or a hardener that has sat too long in storage can compromise a cure that looked right on paper. For contractors and procurement leads sourcing pipe lining supplies, the supplier evaluation starts […]
Large Diameter CIPP Lining for Trunk Sewers and Culverts
Trunk sewers, interceptors, and large culverts carry the highest flows and sit deepest in the network hierarchy. When they deteriorate, the cost and disruption of open-cut replacement can dwarf the original construction budget. Insituform manufactures CIPP solutions engineered specifically for large diameter rehabilitation, with liner systems covering diameters up to 2,500mm and a manufacturing process […]
Trenchless Pipeline Rehabilitation for Drinking Water Networks
Somewhere between a fifth and a third of every litre a water utility puts into distribution never reaches a customer. That is what non-revenue water figures look like across most European and North American utilities, and the pressure to bring the number down is the single largest driver of capital investment in the sector right now. The […]
Lateral Pipe Lining: The Trenchless Solution for Connection Failures
Lateral connections are the highest-stress points in any sewer network. Every junction takes cyclical loading from ground movement, thermal cycling and hydraulic pressure changes. When a lateral fails, inflow and infiltration climbs, treatment plants take volumes they should not be seeing, and reactive maintenance eats into budget earmarked for planned rehabilitation. Insituform invented CIPP lining in 1971 and today […]
How to Specify CIPP Lining on Infrastructure Projects
A CIPP specification lives or dies on the technical decisions written into it before the first liner is impregnated. It must translate CCTV coding, structural condition data, host pipe geometry and site constraints into clauses a contractor can price and install against, without leaving the ambiguity that always surfaces mid-cure. Insituform invented CIPP lining in 1971 when […]
How UV Pipe Lining Works and When to Use It
When the specification calls for CIPP, one of the first technical decisions is how the liner will be cured. UV pipe lining uses ultraviolet light instead of hot water or steam to harden the resin, and that difference in cure method changes the installation sequence, the site footprint, and the range of projects where the […]
Trenchless Sewer Repair for Municipalities
Municipal sewer networks are under growing pressure. Ageing assets, increasing capacity demands, and tighter environmental standards are driving rehabilitation programmes that need to deliver results without tearing up roads and disrupting communities. Trenchless sewer repair makes that possible by rehabilitating the host pipe from the inside, with no open-cut excavation required. Insituform invented this approach in 1971 and […]
What Is CIPP? A Guide for Infrastructure Managers
Infrastructure managers across municipal, utility, and industrial networks are facing the same challenge: ageing pipelines that need rehabilitation without the cost and disruption of full excavation. Cured-in-place pipe, commonly known as CIPP, is the trenchless technology that solves this problem. Insituform invented CIPP in 1971 when Eric Wood developed the first method of rehabilitating a pipe from […]
Insituform Honoured with Earth Champion Award for CIPP Sustainability
Sustainability has become one of the main reasons utilities and municipalities specify CIPP. The trenchless rehabilitation method avoids the excavation, traffic management and material waste of dig-and-replace pipe rehabilitation, and the manufacturers behind it are increasingly expected to back that case with audited supply chain data. The Green Leaves Earth Champion Award 2025/26 has been presented to Insituform for measurable […]
