PVC’s a pain to haul, but once it’s in, you’re not coming back for surprise repairs.
That’s the tradeoff, right? Corrugated’s lighter, but I’ve seen it split just from a cold snap or a rock pressing in the wrong spot. PVC’s heavier and tougher to wrangle, but I’ve never had to dig it up twice. Curious—has anyone tried double-walled corrugated for this? Wondering if it holds up any better or just costs more for the same headaches.
Double-walled corrugated's a bit of a mixed bag in my experience. It's sturdier than the single-wall stuff, but still not quite as bulletproof as PVC, especially if you’ve got heavy equipment moving over it. I’ve seen it hold up okay, but it’ll flex under pressure—sometimes that’s good, sometimes not so much. If you’re worried about long-term reliability and minimizing call-backs, I’d still lean toward PVC despite the hassle. Just my two cents...
I hear you on the double-wall corrugated. It’s definitely better than single-wall, but I’ve seen it get crushed under a skid steer more than once. For spots where there’s any chance of traffic or shifting soil, I just don’t trust it long-term. PVC’s a pain to work with sometimes, but I’d rather deal with that up front than have to dig it up again later. If safety and reliability are priorities, PVC wins for me every time.
I get where you're coming from on the PVC, especially when you know there's going to be heavy equipment rolling over that area. I've had to dig up crushed corrugated more than once when someone underestimated how much weight would end up on top. Still, I do think there are situations where double-wall corrugated makes sense—like temporary fixes or spots with zero chance of traffic. It's just so much faster to install in a pinch.
One thing I'm curious about: how do you handle freeze-thaw cycles with PVC? Around here, shifting soil from frost heave can crack rigid pipe if it's not bedded right. I've seen folks use extra gravel or sand bedding, but even then, sometimes the joints don't hold up. Wondering if you've run into that and what your approach is for long-term durability in those conditions?
Freeze-thaw is a headache for sure. I ran into that last winter—put in PVC for a downspout drain, used a ton of gravel bedding, and still got a hairline crack near one joint after the ground shifted. Ended up redoing that section with more sand mixed in and made sure the pipe had some “give” instead of being locked in tight. Not perfect, but it’s held up so far. I do wonder if flexible couplings would help more than the standard glued joints in those spots...
