LCR Injection Epoxy for Concrete, Fiberglass, Metal, and More; Combines Part A Resin and Part B Hardener for Use in One 10-Ounce Cartridge for Standard Caulking Guns; Use with LCR Crack

We applied this to a crack in our basement. It is the best thing we have found for sealing a crack in a wall. Would definitely recommend this for problem in basement wall!

Used this to try and fill some tiny cracks next to plastic sheathed copper water lines and PVC drain lines in my slab. Due to a an occasional very high water table from underground streams and rainwater, rising water has been forced up thru the slab next to the copper and PVC lines. This created rot and was very attractive to termites. I hoped that I could fill the cracks with this epoxy, but it was very viscous and thin, flowing like light oil right thru the tiny cracks. Unfortunately, it ran out the bottom of the slab. I coated all the exposed slab around the lines and the epoxy dried hard and clear on the horizontal surfaces. Don’t trim the nozzle on the tube. The tiny hole is plenty large to quickly empty the tube using a caulk gun. The epoxy has a strong chemical odor that has lasted for days. It smells like coal tar. I followed up a few days later with LCR Epoxy Repair Paste applied around all the lines and in the cracks. This thick epoxy paste should block the rising water. It is a very thick, grey 2-part epoxy paste that is much messier to apply. It can be smoothed out with a finger or tool dampened with water. Tools can be cleaned with water if done before the epoxy cures. It also has a chemical smell which is not nearly as strong as the clear epoxy from the tube.

Worked great would purchase again

When getting it ready the cap can off and leaked every where

When this LCR injectable epoxy works, it works really well. The problem is the WHEN. Out of 7 tubes, I've had 3 fail. One leaked at the bottom as soon as I removed the red protective cap, so epoxy was coming out the back of the caulk gun--a mess to clean up off my garage floor and off the gun. Another one froze half way through the injection process. The black disc got stuck. I put the plunger in again and moved the black mixing disc up and down a few times, but it was still stuck when I start pumping again, so it was something else causing the problem. Then the seal at the bottom broke again--more mess to clean up only on the basement floor this time. The third one had a plunger that would not screw onto the disc. I tried half a dozen times, but no joy. Instead the disc wound up falling to the bottom, and I couldn't get the plunger to attach to it, no matter what I did. Another lost tube. The main phrase here is a mess to clean up. It took a lot of my time, and then I had to stop the job and reorder more tubes which took days to arrive. So far, I've spent 10 days doing what should have been a 3 hour project, and I'm still not finished. Amazon refunded two of the three tubes because I had pictures. Thank you Amazon. No thank you, Polygem. Never again. I'll use the cheaper but better Simpson CI-SLV next time. I wish I had this time.. I need two more tubes of injectable epoxy to finish. The ports have been in for nearly two weeks and the two unused ones are looking at me like they feel I've let them down. It ain't me little buddies. Like I said, when it works it's great. I got everything mixed and pumping out in six of the tubes before two of them failed, and the seventh tube never got off the bench due to a technical failure to mix. Use Polygem at your own risk of your time and money. I had a 57% success rate. One last thing. The two jars of part A and Part B structural epoxy look big, but they're only 25%, or so, full. Lots of empty space. Interesting. Extra $0.25 ports are $3.50 each with a minimum purchase 4, so use them wisely.

It works very well and fast. Definitely finished the whole and don't stop. Definitely wear gloves also. It does get hot. Soon as you mix it together, use it quickly. No brakes or will dry up. Easy to use and it has no leadering smell.

Arrived on time, worked great for intended purpose. Only needed to be applied one in basement for a leak, easy to use, adhesive holding great, worth every penny.

It works but it's a mess. I had one tube have the plunger stick and then turn which caused it all to come out the back. The return policy (no returns) kills the ease of use as you need enough to not get stuck being empty in the middle of a hole but what is that amount? And without having to buy too much which is how much?
