Effective DIY Foundation Repair

Highly recommend using the RadonSeal Concrete Foundation Crack DIY Repair. The process is straight forward and easy to use. It contained all the supplies we needed including wire brush, gloves, eye protection and even a disposable work mat! Only thing I needed was a caulking gun and vacuum cleaner. I had about a 6 foot crack in the basement that I was able to tackle with this kit. It came with plenty of extras, I still have another bottle of polyurethane foam and ports leftover. It does take time to wait for it to dry before squeezing in the foam so save extra time for this project when you do the fix yourself. I would buy this again if I had another foundation repair project!

Good reputation

We will see how this holds up in our basement over time, but this product was recommended to us for foundation crack repairs and water seepage. Fingers crossed!
