Repairing aging and/or damaged pipes using the cured-in-place process (CIPP) is a great alternative to traditional open-cut methods. As city officials in Toledo recently discovered, it can also be a more environmentally friendly choice as well.
One hundred homes in a Toledo residential district were having difficulties with the lateral connections, particularly during rainstorms. City officials knew that the problem was one they could ignore at their own risk. The longer they put off repairs, the worse off the homeowners would be.
After debating the issue, they decided that lining the damaged pipes was the best and cheapest option. But the more officials looked into it, the more they realized that their solution had a problem.
The styrene/felt liners that they wanted project Continue Reading
It’s a fact: pipe repair methods that involve open cut methods aren’t always right for every situation. This holds especially true when the pipes involved run beneath the surface of buildings and/or other populated areas.
Take for example, the situation that SUNY New Paltz University officials had to face a few years ago. One of the campus dormitories had pipe blockage problems so severe that the question wasn’t if the pipe would break but when. Officials feared that if the blockage were not handled immediately, the break could happen during the busy school year ahead.
The pipe was located 30 feet beneath the dormitory building and ran under common ground for 25 feet. Moreover, the pipe itself changed size — from 4 to 6 inches — and had several bends and elbows.

Formadrain is now the Canadian distributor of an exceptional line of small diameter lateral cutters from the Finnish company Picote. Picote, like Formadrain, is an innovator in its field and has created some remarkable products which are brilliantly simple and effective.
Since 2008, Picote has focused on in-house research and development and now offers a growing range of innovative, patented and patent-pending products, available for the first time to the international market. These resourceful tools and machinery are devised and perfected as a direct result of workforce and on-site feedback and evaluation. The company's Smart Cutter™ system, which Formadrain will carry, won the ISTT new product award for 2012 at the 30th International ISTT No-Dig Show in Brazil.

When it comes to repairs, the size and/or shape of pipes can make a huge difference. An example of this can be seen in the project that the Glenn Research Center in Cleveland undertook to rehabilitate an existing pipe system.
The GRC was established in 1942 as part of the National Advisory Committee for Aeronautics (NACA). Later, it was incorporated into the National Aeronautics and Space Administration (NASA) as a laboratory for aircraft engine research. In 1999, it was renamed after Friendship 7 astronaut and former Ohio senator, John Glenn.
Officials were looking for a comprehensive solution to all their needs. But as it turned out, some of the pipes in the GRC system – about 8% – were not only smaller-sized. They also had small runs, elbow bends, and transitions. So the $50 Continue Reading
Cured-in-place-pipe (CIPP) technology allows engineers to rehabilitate broken or damaged pipes without having to use more destructive open cut methods. Take, for example, the case of the water main break at the Ralph Wilson Stadium in Orchard Park, New York.
In late September of 2013, the main blew while the Buffalo Bills were playing a game against the Baltimore Ravens. Aggravating a difficult situation was the fact that the water main sent a stream of tile and gravel into the sewer pipe, causing even more damage.
The game – which the Bills won – went on, but the Erie County Health Department was forced to shut down the affected area immediately. Officials gave stadium managers a little over ten days to repair both the water main and sewer line and get both inspected and approved Continue Reading
