Seasoned engineer and contractor
Tommy Sander kicked off the session with
an engaging introduction to UV-cured
high strength liners. He explained that
these liners are used primarily in pipeline
rehabilitation and repair, where they offer
a durable, efficient, and environmentally-
friendly solution.
Unlike traditional methods which
require extended curing times and possible
harmful chemicals, UV-cured liners harden
quickly when exposed to ultraviolet light,
minimizing downtime and environmental
impact. Glenn Dobson of Omega liner
used a series of detailed slides and live
demonstrations to illustrate the liners’
superior tensile strength and flexibility.
He highlighted how the unique curing
process not only ensures a stronger
bond, but also enhances the longevity
of the liner, making it ideal for critical
infrastructure projects. The fast-curing
aspect also reduces the time workers spend
in potentially hazardous environments,
thereby improving safety and efficiency.
