I recently bought a house, and I've noticed that my basement leaks during heavy rain. The previous owners had some strange setup in one corner with a trench and a pump that collects water, but it's not exactly a permanent solution. I'd rather keep the water out completely. There's a sump basin (though no pump installed yet) in another corner, and thankfully, the water table doesn't seem to rise with rain. However, I've found leaks around what I think might be a tie rod, which is rusty and probably allowing water to seep in. I know the best way to handle this would be to tackle it from the outside, but my drainage and grading look pretty good, and I'm not keen on digging up the yard. So, my main questions are: is this indeed a tie rod? And if I clean it up and use some hydraulic cement, would that be a viable DIY fix, or are there better options I could consider without hiring a professional?

You're right about that being a leftover steel tie rod from when the foundation was poured. The rust indicates groundwater is leaking in through that area. Hydraulic cement can give you a temporary fix because it expands and can make a good seal around the tie rod. Just make sure to clean off the rust first and maybe chip out some of the surrounding concrete to give the patch a better hold. But keep in mind that if the wall is under pressure during heavy rain, the patch might not hold and could flake off. A more effective DIY solution might be to use a polyurethane injection. It involves chiseling out the tie rod and inserting a tapered PVC port to inject a hydrophobic polyurethane resin that can fill the void and chase the leak. Sure, it’s more work than just patching, but it could save you from future leaks.
Yeah, just be careful while chiseling it out! You can use a chisel and hammer to gently break around the tie rod. If it feels too tough, consider a mini sledgehammer, but go slow to avoid damage.
If you're looking for a quick fix, hydraulic cement will work, but don't forget it’s just a Band-Aid. If possible, get a professional to check the exterior drainage systems. Since you mentioned good grading, it might be worth checking if the bulkhead area is settling or if there are hidden issues like poor sealing at the door. To really ensure a long-term fix, consider investing in a waterproofing assessment. It's like fixing a leaky roof - the sooner you get it sorted, the better you'll feel about your home down the road.
Thanks for the perspective! Sounds like I should at least do some further investigation with a professional.
Definitely! It's better to be safe than sorry when it comes to basement leaks.
Thanks for the explanation! So removing the tie rod sounds tricky. Is there a specific way to do that without damaging the surrounding concrete?
