## Customer Reviews

### ⭐⭐⭐⭐ Decent stuff
*by A***R on May 11, 2021*

I’ve had 3 total crack repairs on my house. I’ve had a professional do one which obviously costs a lot more and I’ve done 2 of them myself. I used a different product first and this product for a different crack. I have this one 4 stars because of the actual product not being as good as the other one I used (it’s no longer available). I do however think it will do the job.Tips for DIY peeps. I used popsicle sticks to mix. Bc you only have a 2 min window to apply you can just throw out stick and use another for next batch. Also make sure you mix for the allocated time. It does feel long but you will be happier with results. Use all of the patch stuff! Even if you don’t think you need to use it all to get a great seal! This is more for the 8ft cracks then the smaller ones. Test, test, test for leaks with water. If your not sure if it’s leaking apply more patch. This saves time once you start the injection process plus the water is needed for the reaction to occur so it’s a win win. Good luck!

### ⭐⭐⭐ Seems Cheap
*by J***S on July 24, 2020*

So, let me start by saying this is not the first crack injection kit that I have used. I bough this one becuase of the unique situation of having to seal a corner crack. Everything seemed very cheaply made, the ports are cheap, the little tube you get doesn't really handle pressure well, and the tube of resin blew out the back of the tube. Never had that happen with other brand of injection kit. I did like how rock hard the epoxy got on the wall. When mixing it up I was concerned with how think it was, but it hardened up QUICK! We'll see how it holds up tp some water soon. If it holds the water, I will come back and change my rating, but for now; it's lackluster.

### ⭐⭐⭐⭐⭐ Great product. Easy to use. No experience needed.
*by A***R on April 2, 2018*

I was more than impressed With this product. I would recommend for any foundation crack repair. Such a great product!
