Custom Designed CIPP Lining Engineering Solutions

ARCH DRAINAGE SOLUTIONS OFFER CUSTOM DESIGNED CIPP LINING ENGINEERING ACROSS SOUTH WALES AND THE MIDLANDS

Custom Designed CIPP Lining Engineering Solutions

CIPP lining has become one of the most widely used trenchless technologies for pipe rehabilitation, offering an effective way to restore damaged drainage systems without excavation. However, not all CIPP lining solutions are the same. While many contractors rely on standard liners and generic installation methods, at Arch Services we take a very different approach. Every CIPP lining solution we deliver is custom designed to suit the specific conditions of the pipe, the surrounding environment, and the operational demands placed upon it.

This engineering‑led approach is what sets us apart and ensures our solutions deliver long‑term structural performance rather than short‑term fixes.

What Is CIPP Lining?

CIPP lining, or Cured In Place Pipe lining, is a trenchless pipe repair method used to rehabilitate damaged drains and sewers from the inside. A resin‑impregnated liner is installed into the existing pipe and cured in place to form a new structural pipe within the old one. This restores integrity, improves flow, and extends the lifespan of the asset without the disruption associated with excavation.

While the process itself is well established, the success of a CIPP lining project depends heavily on how that liner is designed, specified, and installed.

Why Standard CIPP Solutions Can Fall Short

In much of the industry, CIPP lining is treated as a one‑size‑fits‑all solution. Liners are often selected based on pipe diameter alone, with limited consideration given to external loading, deformation, ground conditions, or long‑term performance requirements. In some cases, little or no structural calculation is carried out at all.

This approach can lead to premature failure, reduced lifespan, and compliance issues, particularly in commercial, industrial, or infrastructure environments where pipes are subject to high loads and constant use.

At Arch Services, we believe CIPP lining should be treated as an engineered structural solution, not just a repair technique.

Our Custom Design Process

Every custom designed CIPP lining solution begins with a detailed assessment of the existing asset. We carry out high‑quality CCTV surveys to understand the pipe condition, defects, diameter, material, and alignment. From there, our engineering team designs the liner to suit the exact requirements of the site.

This design process considers factors such as deformation limits, live and dead loads, soil conditions, hydrostatic pressure, liner modulus, Poisson’s ratio, and required safety factors. Liner thickness and material selection are calculated, not estimated.

By designing each liner specifically for its environment, we ensure the finished installation delivers genuine structural reinforcement and meets relevant industry standards and local authority requirements.

Engineering‑Led Installation

Once the liner design is approved, our experienced teams carry out installation using the most appropriate curing method for the project. This may include ambient cure, heat assisted curing, steam curing, or UV curing depending on access, pipe size, and site constraints.

Throughout the process, quality control is critical. Following installation, we complete a post‑installation CCTV inspection to verify liner integrity, finish, and performance. Full reporting is provided, giving clients complete confidence in the work carried out.

Benefits of Custom Designed CIPP Lining

A bespoke CIPP lining solution offers significant advantages over generic approaches. It provides improved structural strength, greater resistance to deformation, and a longer service life. It also reduces the risk of future failure, minimises maintenance requirements, and delivers better long‑term value.

For clients operating in regulated environments or submitting tenders, custom designed CIPP lining demonstrates a commitment to technical excellence, compliance, and sustainability.

Where Custom CIPP Makes the Difference

Custom designed CIPP lining is particularly valuable in complex environments such as commercial drainage systems, industrial facilities, highways, culverts, and public infrastructure. It is also ideal for projects where access is restricted, excavation is not viable, or long‑term performance is critical.

Across South Wales, Bristol, and the West Midlands, we support local authorities, contractors, developers, and asset owners with tailored CIPP solutions that solve problems other methods cannot.
