Is it normal for plumbers to chip away at foundation beams for PVC?

You need to call a stop-work on this immediatly because those grade beams are designed to handle specific tension and compression loads that are now compromised. When they start hacking out chunks of concrete and hitting the **rebar**, they aren't just making a hole; they are potentially ruining the beam's ability to span the distance it was engineered for. If they cut through the bottom tension bars or the top compression bars, the beam won't perform like it was designed to under load.

The fact that they didn't use a **core drill** tells me they either didn't have the right gear or didn't care enugh to rent it. Sledgehammering or jackhammering out a beam like that creates micro-fractures in the surrounding concrete that you can't even see. And that pipe gap? That's just lazy work. If there is a literal gap inside the beam, you're looking at a future leak that will wash out the subgrade under your foundation, eventually leading to settlement issues or a collapsed pipe. Before you pour any more concrete or put a stick of framing on that foundation, you need a structural engineer to come out and look at it. They'll likely make the plumbers or the GC pay for a repair plan, which ussually involves cleaning the area, tying in new rebar with high-strength epoxy, and using a specialized **non-shrink grout** to fill the voids. Don't let them tell you they can just slap some sack-mix in there and call it a day. It's a total mess, but it is fixable if caught now. If you wait til there's a roof and a second story on that house, you're looking at a much more expensive nightmare. I've seen guys try to fly under the radar with this stuff by burying it quickly, but a proper inspector is going to have a field day with those exposed bars anyway. Better to deal with the headache now than a foundation failure in five years.

Man, that sounds like a total nightmare. I'm just starting to learn about this stuff for my own project, and I'm wondering—wouldn't the local building inspector catch somthing like that during a routine check? I always thought they were supposed to be the safety net for this kind of hack job. Also, if you have to hire a structural engineer to fix thier mess, does that cost usually fall on the homeowner or the contractor? I'd be terrified to even walk on that slab if the rebar is just hanging out. defintely keep us posted on what the GC says when you confront them.

Honestly, that pipe gap is the biggest tell here. It means they didn't even bother with a pressure test. In most places, you have to fill those lines with water or air to prove they don't leak before you can even think about burying them. If there's a literal opening in the beam, they're just hoping you don't notice til they're long gone.

I’d grab a level and check the pitch on every other run they did. If they’re hacking beams with a sledgehammer, I gaurantee your drainage slope is all over the place. These guys aren't pros; they're hacks who need to be kicked off the site before they cause more structural damage.

Definitely hold back any remaining payments. ussually, these hack-and-slash crews know they messed up and will try to bury it under concrete ASAP to hide the evidence. I’d be checking thier license and insurance info immediately. If they're willing to leave a literal gap in a main line, there's no telling what else is wrong behind the walls or under the dirt.

You’re likely looking at a complete redo of that section. It sucks, but paying for it now is way cheaper than a foundation repair ten years down the line when your house starts tilting.

One thing nobody mentioned is that those pipes shold have been sleeved. You never just pour concrete directly against PVC in a structural member becasue of expansion and contraction. Even if they hadn't hacked the rebar, the lack of a wrap or sleeve means that pipe is going to crack or the concrete will spall over time. Since you’re probaly going to have to chip out more to fix the rebar, make sure they use a proper foam wrap or a larger diameter sleeve when they re-run it. It's basic code for a reason.
