Cracks in your home's foundation can allow water to seep in and cause serious structural damage over time. Choosing the right epoxy to repair these cracks is crucial for a long-lasting fix. When shopping for the best epoxy for foundation crack repair, there are a few key factors to consider:
First, make sure to choose an epoxy formulated specifically for concrete and masonry repair. These are engineered to bond tightly and permanently with materials like concrete, brick and stone. General purpose epoxies may not adhere as well or expand and contract at the same rate as the foundation.
Also look for an epoxy with a very low viscosity or thin consistency. This enables the epoxy to deeply penetrate into cracks and create a strong repair. Avoid thicker epoxies that may not flow all the way to the back of the crack.
It's also important to select an epoxy designed for below-grade use. Epoxies made for above-grade repairs may not stand up well to the moisture and soil stresses that foundations endure. An epoxy with waterproofing additives is ideal.
Does your foundation have any active leaks or moisture? Are there multiple cracks that may require more extensive repairs? Determining the root cause of cracks and any water intrusion issues is key before applying epoxy. Trying to patch symptoms without solving the underlying problem will likely lead to cracks reappearing.
Choosing the optimal foundation crack repair epoxy involves understanding your specific situation. With the right product, epoxy can provide long-lasting repairs that keep your foundation stable for years to come. Carefully weigh the criteria and find the best solution for your home's needs.

1. Pro-Seal 10ft Diy Foundation Crack Repair Kit
I had a hairline crack in my basement wall that would seep every time it rained, which is quite often in our location in Pennsylvania. After doing a lot of research and getting a recommendation from a friend in heavy construction, I decided to use Radonseal polyurethane to fix the issue.
Before using the product, I spent a lot of time prepping the wall. I removed all the previous failed attempts at fixing the crack, including epoxy paint, hydraulic cement, roofing tar, caulking, and more. It was quite a mess, but I wanted to start fresh. I even went as far as grinding the wall to ensure everything was completely removed. I cleaned the area with Dawn dish soap and water, followed by rubbing alcohol to make sure it was as clean as possible.
In the area where the crack was the worst, I drilled holes at a 45-degree angle every eight inches, intersecting the crack. This was not necessary, but I thought it would help the polyurethane penetrate the crack better. I also prepared mixing boards for the epoxy, as you can only use a small amount at a time before it hardens.
I followed the instructions provided with the product, pasting the crack with the epoxy and attaching nozzles to the drilled holes. Before attaching the nozzles, I cleaned the wall again with rubbing alcohol and made sure it was dry. I flushed each nozzle and crack with water, making sure to use plenty of water to activate the polyurethane's expansion. I had to use multiple bottles of water to flush all the nozzles.
I didn't experience any issues with the injection tube leaking, as some others have mentioned. I started at the bottom nozzle and followed the recommended pumping and waiting times at each nozzle. I pumped for 30 seconds, waited for 30 seconds, and then pumped again for about 15 seconds, repeating this process until I couldn't pump any more polyurethane into the crack. I maintained constant pressure on the gun throughout the process.
In the area where the crack seeped the most, it took a significant amount of polyurethane during the first pump. After the first pump and waiting period, I was surprised at how much more material the crack could take. After the second pump, it became more difficult to pump, and I could barely get a third pump in before the polyurethane began to set. I repeated this process for each nozzle, and in some cases, the polyurethane started seeping from the nozzle above, which I considered a good sign.
Once I finished injecting the polyurethane, I removed the nozzles and started removing the excess epoxy from the crack. This turned out to be quite a difficult and messy task, and I wasn't able to completely remove it. I decided to cancel the idea of grinding it off due to the potential dust in my home.
After three weeks, we experienced several heavy storms and minor rains, but the wall remained completely dry. Previously, it would have seeped or sweated with each rainfall, but since using the Radonseal product, there has been no sign of any moisture. I am extremely satisfied with the results and would highly recommend Radonseal polyurethane for fixing basement wall cracks.

3. Leakstop – Ultimate Basement Crack Repair Kit
I recently had a crack in my basement that was causing a leak, and I decided to give this product a try. I must say, it was very easy to use and the repair was done in just a matter of minutes. Since then, I haven't experienced any more leaks.
I did have a minor issue with the amount of expanding foam and epoxy provided in the kit. I ended up having twice the amount of foam and only half the amount of epoxy that I actually needed. However, I was able to purchase some extra epoxy to finish the job. It's worth noting that I did have a few leakage or blowout incidents under some of the injection ports.
To avoid any mishaps, I would recommend wearing rubber gloves and having a few extra pairs on hand. I also found that using plastic butter knives was helpful during the application process. The epoxy dries very quickly, so it's important to start with a small amount and focus on the bottoms of the ports for the first application. This way, you can get a feel for the amount needed and ensure proper coverage.
In my case, the trouble area was the bottoms of the ports. Luckily, the injection foam ran out just a few ports shy of completing the job, which allowed it to expand and cover the remaining crack. I would suggest stopping a few holes short to avoid any excess foam.
After completing the injection, I waited a few days to remove the excess material using a chisel. I was pleasantly surprised by how easy it was to clean up. However, I did have quite a bit of material on the floor, so I recommend taping down plastic to protect it. I also applied thick duct tape along each side of the crack before applying the epoxy. This provided a straight hard edge, making it easier to remove the tape later on.
Once everything was cleaned up, I sprayed paint over the area for a finished look. Since completing the repair, I haven't experienced any further leaks despite heavy rain. Prior to using this product, I would have about half a gallon of water in my basement after every rainstorm.
4. 20' Fast Set Concrete Foundation Crack Leak Repair Kit, Stop Leaks In Basement Walls
I have been using this product for a while now and I must say, it lives up to its claims. This is actually my third purchase and I don't think it will be my last, depending on how the rest of my walls hold up. However, I do have a few suggestions for improvement.
Firstly, the caulking gun that comes with the kit is not up to par. Many others have mentioned this as well, and I agree. Considering the price of the kit, I believe a better quality caulking gun should be included. I ended up purchasing a separate heavy-duty caulking gun from a big box store for around $20, and it made a huge difference in the ease of application.
Secondly, I would recommend including a couple more pairs of nitrile gloves in the kit. It would be more convenient for users to have extra gloves on hand, especially when working on larger projects.
Lastly, I found that the kit could benefit from having 3-5 more surface ports. The amount provided was just enough for the crack I was working on, but it would be helpful to have some extra ports for larger or multiple cracks.
Despite these minor issues, the product performs exceptionally well. It is on the expensive side, but it does its job effectively. I have yet to come across another product that matches its quality and performance at a lower price point. Applied Technologies is definitely a reliable choice for these types of needs.
I used this product to patch two leaking cracks in my concrete foundation. The first thing I would advise is to disregard the included caulking gun and invest in a high-quality one. I purchased a heavy-duty caulking gun from a reputable store for around $20, and it made a world of difference in terms of ease of use.
Following the instructions carefully and taking my time, I was able to successfully fix the cracks. However, I would recommend applying the epoxy in a heavier amount than what is suggested. Even though I thought I applied a thick layer, I still experienced some leaks. I ended up using all the epoxy provided and still had some foam left over, so it might be wise to purchase extra if you have multiple cracks to address. The kit I purchased claimed to cover 20 feet, but it was barely enough for my needs.
5. Watertight Crack Repair Kit For Concrete Foundations
I recently purchased and used the regular epoxy paste and epoxy resin kit for a crack repair in my basement. I must say, it worked great! The instructions were clear and easy to follow.
Installing the injection ports was a breeze, and mixing the epoxy paste was simple. I found it easier to apply the paste using a 1" margin trowel, ensuring a ⅛" thick layer around the base of the ports and a 4" wide swath centered over the crack.
The paste hardened in about 45 minutes, and I followed the water bottle instructions to refill it several times to ensure all the ports were flowing properly. It's important to note that the epoxy resin injection process releases a significant amount of energy after 5 minutes. I took precautions by protecting the floor with plastic and a drop cloth to prevent any leaks.
After using the product for a full year, I can confidently say that it has held up well. The crack in my basement wall, which used to leak water during heavy rain, is now completely sealed. I applied the peel-off epoxy as directed and filled each port, which took around 2-3 minutes per port.
The only downside I experienced was that the peel-off epoxy was a bit challenging to remove. In hindsight, I should have applied a thicker layer to make it easier to peel off. Additionally, the kit included extra items such as goggles, gloves, and a garbage bag that I didn't find necessary.
If you're looking for an effective solution to repair cracks in concrete, I highly recommend giving this epoxy paste and resin kit a try. It's a great product that delivers on its promises.
