UV Cured Pipe Relining in Perth
UV curing is one way we set the resin liner once it is in position inside your pipe: a light train, not a heat source, pulls through the liner and cures it as it goes. It is one method among a few we use, and we pick it because of how it suits the job, not because it is the only option.
- Cured by light, not an external heat source
- One of several curing methods we choose between
Cured by light, not heat
The resin in the liner sets on exposure to UV light, so there is no boiler or steam plant running on site.
Not the right fit for every run
Very long sections or awkward access can suit a different curing method better. We choose based on the pipe, not habit.
Fremantle and across Perth
We run UV cured relining on residential and commercial jobs across the Perth metro area, including Fremantle.
What UV curing is
A resin-impregnated liner is inserted into the damaged pipe. Once it is in position, a UV light train is pulled through it, curing the resin as the light passes along the liner's length. The result is the same as any cured-in-place relining job, a new structural liner bonded inside the old pipe, but the way the resin sets is specific to this method: light exposure, worked along the pipe by the light train itself, rather than an external heat source applied to the whole liner at once.
How the light train cures the liner
Why we choose UV over steam or hot-water curing
Steam and hot-water curing both work by heating the liner from the inside, which means running a heat source and often extra plant on site for the duration of the cure. UV curing skips that setup: the light train does the work as it travels, with no boiler or hot-water rig needed alongside it. For a job where access is tight or the site cannot easily accommodate extra equipment, that is a real practical advantage.
It is not automatically the right call for every job. A very long run, a section with a lot of bends, or a pipe with especially awkward access can suit steam or hot-water curing better, and we will tell you when that is the case rather than forcing UV where it does not fit.
Where we use it
UV cured relining suits a wide range of residential and commercial pipe diameters, and it works well on runs with reasonable, if not perfect, access to the pipe. Sewer, drain and stormwater lines can all be relined this way, depending on what the CCTV inspection shows.
The liner itself is felt or fibreglass saturated with a light-reactive resin, chosen and sized to the diameter and condition of the pipe it's going into. Because the light train cures the resin as it's pulled through rather than all at once, the same rig can handle a straightforward straight run and a section with a gentle bend or two without changing equipment between them.
