Scalable CIPP coatings and pipe rehabilitation solutions

To do something, you have to take new paths. This has always applied to IMPREG since the birth of the company in 1999.

National Manager Kevin Woolf says trenchless australasia that IMPREG recognized early on that trenchless pipe rehabilitation using hardened-in-place liners (CIPPs) is the technology of the future.

Continuing this path, the company’s CIPP coating systems are developed using innovative high-tech processes and set new standards.

“Our success proves us right. IMPREG CIPP coating systems for UV curing are used all over the world,” he says. “We are a reliable solution partner at all times, and we are committed to the highest sustainable quality and environmentally responsible driving.”

Woolf explains that the IMPREG GL16 coating was developed in 2016 for all common pipes from DN 150 to DN 2000.

Thanks to the good material characteristics and the new fiberglass design, IMPREG was able to develop more finely nuanced wall thickness gradations.


Not only does this benefit the company’s customers financially, but the IMPREG GL16 coating makes large dimensions easier to manage.

“With the IMPREG GL16 coating, the company has consistently strengthened its position as the technology leader in the market segment from DN 1200 upwards”, says Woolf.

“The unique construction of the IMPREG liner allows for some level of compensation for pipe dimensional variations. We can produce defined dimensional changes in our factory.

“In the Australian Pacific region our js GL16 range is made up of 0.8mm fiberglass layers and an inner sheet, outer fleece and DN150 yellow UV protective sleeve to DN2000 with wall thickness ranging from 3mm to 14.6mm.”

Woolf points out that IMPREG’s high-tech CIPP liners are simply inserted into the pipes through the manholes and cured using UV light. The rehabilitated pipe can then be returned to service immediately after curing, with the company able to rehabilitate up to three pipes in a single day.

With a warehouse located in Brisbane, standard liners in Australia and New Zealand are available to ship across the country, with ready made liners for: DN150, DN225, DN300, DN375, DN450, DN525 and DN600 .

Woolf says IMPREG’s main focus this year is to continue to support its client both onsite and technically.

“Our biggest goal for 2022 is to continue our after-sales service,” he says. “Customers’ success is our success, which means that our after-sales service is just as important as the quality of our products.”

As part of the company’s after-sales service in Australia, Woolf is able to assist with structural design, review CCTV on worksites and provide on-site technical support.

“New customers will also have the opportunity to attend a training session and learn how we are already implementing the trenchless pipe rehabilitation of the future,” he says. “Our application engineers are on hand for your first project and assist you with advice and assistance during the installation of the IMPREG liner.”

Without the need to stop a project, IMPREG is also able to quickly and efficiently rehabilitate pipes carrying aggressive or higher temperature wastewater.

“IMREG CIPP liners are future-oriented, high-tech products that offer all options for the fast, efficient and cost-effective rehabilitation of pipes of very different diameters,” says Woolf. “With our liners, we at IMPREG are setting new standards that will lead us into the future.”
