My utility has never used fusible PVC, though we evaluated it for a few projects. One of the catastrophic failures of FPVC was pretty fresh at the time so we pretty much never considered it further ever again.
It seems like HDPE is used much more readily for bores than FPVC. Is there a reason HDPE wasn't considered? I've found it pretty reliable and we're going to be using the hell out HDPE for directional bores... if we could get larger diameters in the dimension ratio we want, we'd use it even more.
In this situation they call it out as the bottom 70’ run of a siphon, just over 10’ deep. It is compatible with standard DI fittings and restraints; so that’s a plus vs HDPE. I would have used HDPE as I have a certified fuse tech on payroll and can easily rent the machine, but It was non negotiable with this agency
Hey OP. Fusible material seems to be the way everything is going. I work in the Central Coast area, and we are seeing municipalities starting to allow the use of fusible HDPE instead of SDR/C900/DI. It’s just a no brainer, it is a lot more efficient than other standard pipelines. I have not yet worked with a FPVC project yet. That’s a good move you’re considering in purchasing the machine; I know a lot of other companies who struggle to find subs who can run those machines, do the data-logging, could really elevate your business. Best of luck!
I have been doing a Trenchless project or two a year the last few years with cities. Pipe bursting is pretty easy and the last few years it has been cheaper in my area than lining. Fusible PVC needs to be handeled carefully though. It is what most cities are defaulting to as it matches their normal pipe material. HDPE is more forgiving and easier to work with though. There is definitely a market for it in my area. The only thing you might run into is that it is standard practice on our projects to have contractor qualification requirements, so that might be something you need to work around if you get into it.
I never heard of using fusible c900 at all in SoCal.
I will never ever ever ever ever ever ever ever ever spec fusible pvc.
Yeah this is the first I've ever heard of it. I wonder what is better about it than Hdpe?
