Review: Rethane Cracks filler works - Product and instruction are spot on. I didnt use the kit until 5 months after I purchased, which may have created my only issue. The epoxy tunes were so firm, I had to cut the tunes open to extract the two-part epoxy. It was messy and I broke most of the wood applicators/mixers. Maybe that's why they give you so many. I had one left. The other supplies, vinyl gloves, plastic ports, extension tube are all good quality. The caulk gun was OK. When I applied a decent amount of pressure, it slipped. I ended up using my old caulk gun. The urethane foam worked well. I couldn't quite duplicate the fill process from the video...where the urethane spills out of the next port above. However, I could see the foam in the next port, so I would then proceed. The foam expands 2 or 3 times the liquid volume. The injection times per port were also accurate. The Thin cracks easily took 5 minutes to spread. Good product. I would recommend to anyone for their basement cracks. Contractor price was $500 per Crack, so I saved $350. Good luck. Watch the video.
Review: Photos of crack repair - Amazing product that worked exactly as advertised. After watching instructional video was easy to apply, worked quickly and was able to fix a foundation leak that was causing damage to my home. It has been almost six months and many heavy rainstorms since using this product and have had zero recurrence of the troublesome leak.

## Questions & Answers

**Q: the crack on my wall is wider. maybe 1 inch. maybe more. would this product work?**
A: I had a fairly wide crack with a couple of 6" sections where pieces had come out and left at least a 1 1/2" wide void. I had some thin set (the cement kind NOT the premix which is not water proof) from ceramic tiling I had done and used that to embed and overcoat fiberglass drywall tape on those sections. I used the epoxy paste for the ports affixed to narrower places on the crack as well as the crack itself. It worked like a charm.

**Q: I bought this kit but i need more of the foam. Can I purchase extra tubes of the Hydrostop foam only?**
A: I don’t know, check with manufacturer👋

**Q: I have water seeping up around an iron sewer drain through the floor of my basement. Not a big gap around the pipe. Will this product seal the pipe?**
A: Troy,Disregard the other email I sent you.  I did not have all of this information.  You CANNOT use these materials on floor gaps and cracks.Thank you.

**Q: Is this Hydro Stop 300?**
A: Hydra Stop 300 is in the kit

### ⭐⭐⭐⭐ A few tips of advice...
*by J***K on January 25, 2016*

I'll give the product 4 stars if it does what it says it'll do because it was relatively easy and much cheaper than having a professional do the exact same thing. I'll give Applied Technologies zero stars, though, due to their lack of customer support. I've called them only to ever leave voicemails. And the voicemails were never returned. I'll not know if the product technically works (until the next major rain storm) but let me give some tips on the process. FWIW, I had a 7'(ish) crack that was about 1/4" wide. -Cover anything and everything that looks like it could be a crack with the poxy paste. -Cover the ports completely. Go overboard on the poxy paste because there was plenty for 7' worth of the foundation wall crack. -The poxy paste sets pretty quickly so don't take too much time applying it. I applied in small increments and just kept mixing a little at a time from the tube. -Be careful capping the ports. I capped one of mine and it snapped the whole port off the wall and urethane/foam rushed out all over the wall. I held the port back in place with a bunch of paper towels for about 5 minutes and it seemed to set up. <---if the product fails, it's probably because if this step but now there's nothing for me to do but cross my fingers. -Squeeze the urethane in very slow. The foaming starts instantly and it'll help get the urethane up to the next port above. Other than just taking your time and keeping an eye out for what I mentioned above, anybody can do this. Plus, there's always something great about feeling self-satisfaction for fixing something in your home.
