DIY Leaky Basement Wall Crack Repair Kit (10 ft.) for Homeowners - Repair Poured Concrete Foundation Wall Cracks, the Waterproofing Contractor’s Preferred Solution

I have purchased this foam kit several times and used it with excellent results. The foam does the job in stopping leaks. The kit comes with 12 injection ports which cover an 8-foot length when spaced at 8-inch intervals. The two-part epoxy used to attach the ports and cover the surface of the crack becomes tacky in under 15-minutes and hardens, ready for foam injection, in less than an hour. Be sure to lather on plenty of epoxy, especially when attaching the ports, to ensure the ports do not pop off and that there are no pinhole leaks when foam is applied. Water is injected into the ports prior to the foam. A squeeze bottle is provided in the kit, but I use a garden sprayer under pressure. That serves to moisturize the entire crack, needed for foam activation, and also reveals any pinholes in the epoxy. The main difference between this kit and others, IMO, is the plastic hose which connects the foam mixing nozzle with the injection ports. The connections at both ends are solid. When one tube is emptied, it is easy to clamp off the hose, unscrew the mixing nozzle and attach a new tube to the existing nozzle. No need to prime a new mixing nozzle.Three recommendations for first-time users: 1) Use a decent heavy-duty caulking gun with a good thrust ratio. Not one of those cheapies where the handle bends easily. The foam dispenses as a thin liquid, so viscosity a not the problem, but a little pressure is needed to insure the liquid is pushed into the crack higher than the level of the port. 2) Tear off the paper around the top of the foam caulk tube. Doing this makes it easy to see the position of the plunger and determine when the tube is empty. 3) Filling the crack will require more foam than it appears. Order more than you think you need. I assume that I will need one tube per 24-inch length of crack. Better to have some left over than run out in the middle of the job.

This was my first time doing a foundation repair myself, so naturally I was a bit nervous. Am I going to permanently damage my foundation if I do it wrong? Am I using the right product? Will it hold up over time? I do carpentry and even a bit of basic masonry myself without a problem, but this was for a poured basement in a 55 year old house. I plan on living here a while, ya know? And once the polyurethane is in the crack, there's no "re-do" without ripping apart the foundation.I did a bunch of online research before picking a product. For a non-structural crack, the recommendation seems to be for a urethane foam, not epoxy. I had to fix a leaking vertical crack that started at the corner of my basement window and ran down to the floor. Total height of the crack was about five feet. At its widest, it was about 1/8th of an inch. It narrowed to a true hairline at the floor.The kit provides two tubes of urethane, and I used maybe one and a quarter tubes. I had more than enough epoxy resin to cover the crack. There's an online video from the company that explains and demonstrates the whole procedure, and it was absolutely accurate and helpful.The whole procedure was easy and step-by-step. The kit did have everything you need except the caulking gun and a disposable plate. Also, if you have really big or really small hands, you'll want to get your own gloves to fit. The video suggests layering your gloves so you can take off a layer if the outer ones get sticky. It's a good idea. You should definitely do it.Anyway, I recommend the product. It was easy. It was actually kinda fun. It worked precisely as advertised.I will be watching the crack for any signs of leakage when we get significant rain over the next year. If I see any leaking, I'll definitely add that to my review and change my rating for the product. If this is all you see and it's still 5 stars from me, then you know it hasn't leaked.

I could of given this product a 5 star because it did stop the leak, but it didn't go according to plan or how it was supposed to go. My package came without a wire bush. Not a good start, because I put a day aside to do the job. Luckily, I had my own wire brush and had the crack pretty much prepared for the application. They were very nice to deal with and sent me the brush that I got 4 days later. The 2nd thing that kinda bothered me was the instructions say not to do when it's leaking or wet. Well, I wouldn't of ripped apart my finished basement wall if it wasn't leaking and I'll be damned if I'm going to wait for some dry season to start on it. But, the instructions also said to use a heat gun to dry it up if necessary. That I had, so from there on, it should of gotten better, but it didn't. After I dried up the spots enough to work with, I got all the plugs in place and the epoxy on. That being done, the instuctions say to pour a few cups of water in the hightest one and allow it to trickle out the plugs below. That didn't happen, I put three cups of water in and it only trickled out one midway down. So, I just started with the tubes and caulk gun. I started with the bottom most plug and began shooting the foam in. After 10 minutes, it never came out the 2nd highest hole but managed to build up a lot of pressure in the flex tube, so much in fact that it blew apart at the connection near the gun. I had foam everywhere, good thing I had the gloves and glasses on. After reconnecting, I gave up on the bottom hole and went to the next one up. To make note here, the foam never came out of any of the upper plugs, I had to put stoppers in each and continue to do one at a time until I reached the top. I was not pleased with the process but, after I let it set up over night, I removed the plugs and been watching it for the last 4 weeks. We've had some horrendous rain and crappy weather here in Buffalo this past month and the crack never even shown a sign of dampness. The point here is, I feel like I botched the job from the get go and it worked pretty damn good. I can only say that if all went according to plan, how much better could it be? It worked, and I'm happy. The drywall is back up and the panelling is going in this week.
