The History Of CIPP Lining And How It's Used Today

There are a few sewer construction methods, but Cured-In-Place-Pipe (CIPP) is rising in popularity. CIPP lining is faster and more convenient because little to no digging is involved. The technique is 40 years old, and one cannot help who is responsible for its fruition and how industries benefit from it. This article is dedicated to the history of CIPP lining.

How It All Began

Necessity is indeed the mother of invention, as the birth story of the CIPP lining started simply as a leaky pipe in the home garage. Any CIPP lining manufacturing company knows the story so well. It was 1971 in London, England, when an agricultural engineer named Eric Wood created the CIPP method. He didn't want to damage his whole garage door, only to repair a water leak. He eventually found a way that is what we know today as cured-in-place-lining.

The first CIPP lining performed was in an egg-shaped Victorian sewer. It is located in one of London's Boroughs called Hackney. It is still in existence today.

But back then, he called it insit u form. The term was originally in Latin, meaning 'form in place.' While Eric Wood worked in a different industry, his knack for inventing encouraged Brian Chandler, known as Brian Holmes, to approach him regarding the pipe issues of Thames Water. They needed another method that the conventional cement mortar lining could not fix. Wood eventually formed the Insituform Group Limited with Briand Chandler.

Eric Wood's successful invention became a preferred process in sewer rehabilitation across the United Kingdom's aging pipes. Construction companies were later granted licensing, including in the countries of Germany, Denmark, Austria, Sweden, and Finland.

After finding a solution, he filed for U.S. patent number 4009063 on January 29, 1975. Two years later, it was finally granted on February 22, 1977. Currently, there has been about an estimated 50,000 km of CIPP lining installed all over the world since its invention in 1971.

Why CIPP Lining Is Popular Today

Classic or contemporary homes and businesses benefit from CIPP lining up on their pipelines. Cured-in-place-pipe lining is considered the most innovative means of repairing residential and municipal pipelines. Construction doesn't need to dig pipes to fix them; instead, it only uses a combination of Perma-liner coating and air pressure. The tools and techniques required for CIPP became known as trenchless technology. It's not surprising anymore why many prefer the CIPP lining method because it is an affordable way to repair pipes. With it comes many advantages that both public and private sectors enjoy today.

The Uses Of CIPP Lining Solutions

It's the only method that can quickly repair damaged pipelines in hours, making it revolutionary. The process involves using liquid-based liners to seal and cure the interior part of pipes. The coating transforms into a solid wall capable of lasting for decades.

There is no need to call for contractors to do the digging and make a mess of your home. CIPP lining method is non-invasive and easy on the pocket, making it the best trenchless technology anyone can agree on.

Apart from the sewers, CIPP lining also applies to culverts. Some companies will use different systems depending on the requirements and conditions of the culverts. Applications on cross-sections and non-circular pipelines are available today for those measuring 400mm to 4m in diameter. Engineers can offer services spanning up to 150 years due to the system's reliability, which provides resistance to acids.

Cured-in-place pipe lining is also used on storm drains and pressure pipelines for gas, water, and liquid waste. Modern CIPP lining processes work by placing liners with specific types of resins into the pipelines. The existing pipe is treated while the resin inside cures to form a solid wall. It is more environment-friendly, mess-free, and affordable this way.

The pipe liners are cured using various techniques and materials, such as resin. Pipes and culverts treated with resins harden using ultraviolet light, hot water, steam, and air. Today's many materials are liquid epoxy, polyolefin three-layer coatings, and epoxy coal tar.

Manufacturers also produce ready-made pipelines strengthened and cured with resins with UV light. The curing time is also significantly shorter. Old and new piping sections can bond in as fast as seven minutes. The creation process is also safer because it reduces the dangers of chemical inhalation through robotics and machinery.

In Conclusion

Various industries are enjoying the benefits of CIPP lining solutions today due to the creativity and inventiveness of one man. Homes, establishments, and public facilities benefit from the mess-free and affordable solutions of CIPP lining. Repairs and maintenance are also eco-friendly and offer fewer downtimes, which is valuable for businesses. It is a solution that will continue to aid society for many years.
