Fits and works as advertised
Easy to use. And I plugged it right in the rod hole. Seems to be keep water out. Hopefully it stays this way forever.

These plugs work great!
Bought a house which we thought had all the rod holes repaired. I was wrong and we started to have a few holes weep/leak a bunch of water after a hard rain. Used these to seal up a few rod holes and after a hard 2-3+ inch rain fall, these plugs did its job and the blue stuff expanded and kept the basement dry. Bad news is after the big rain storms we just had a few more rod holes suprised me with more water leakage. Ordered a few more to have on hand. These are ridiculously easy to install and work great! Glad I found these. I was worried I was going to have to hire someone to fix them. Saved a ton BY doing it myself with these plugs. Just buy them and have a few extras for a peace of mind.

Super cool
Found this on line by chance when searching epoxy on how to fix foundation cracks/rod holes.What a genius, whoever created this is brilliant. We had a rod hole that was gushing like a geiser and this simple fix worked amazing. Thank you to the creator of this awesome product.

What is a Snug Fit?
I bought 45 these to repair my rod holes. I cleaned the holes as best I could and installed the plugs very quickly. Some of the holes seemed a little too tight for the plugs but I was able to get the entire blue part of the plug in each hole. Installation was just a few minutes each. I even installed a plug on a hole that was leaking water at the time of installation.After a very wet spring I am happy to say that not a single plug has leaked a drop of water. Very impressive!My only concern is the directions. The directions only say: "Once you have it SNUG so as not to spin within the hole, lightly tap the end of the coupler with a hammer until the coupler end is flush with the wall. Finish tightening to a SNUG fit with a 3/8 inch socket. Do not overtighten, rather a nice SNUG fit." Well, if not spinning in the hole is already SNUG, how can you finish tightening the plug to the next level of SNUG? I would prefer the directions say something like: tighten plug until it wont move in the hole, then tighten another full turn... or something like that. If mine eventually fail, I am going to blame the vague directions.

Pricey But Appears to Work
After 30 years in out home, the poorly sealed rid holes in our basement began to leak. I initially used #7 cork to plug some of the rod holes but ran out of corks and tried these.These plugs are WAY more expensive and harder to push into leaking rod holes than corks (you must use sealant with corks - and likely these plugs as well) but they appear to be working. We’ve no leaks from either the TRX or cork plugs.

they work!
These worked very well. It's been almost 9 months and no water has leaked through where they were installed. Easy to understand and install even in old poured walls, it was very simple to place.You will need a masonry bit about 1/2" to make the hole and some hydraulic cement to fill the holes once they have been installed.

Temporary fix
It’s not a permanent fix. It’s good for quick and short period fix. Because it doesn’t seal threw the whole thickness of the wall and it can get rusted.
