Well, I bought your sealer repair kit to fix a cellar water wall crack at my sister's house. Everything went okay following your instructions. There was a previous surface repair attempt made several years ago that did not work. What I did was drill a hole where each surface port was to be placed. I used a 3/16" drill to a depth of about 1". The reason was from the other repair. I wanted to make sure the crack at the surface was not plugged. Also, I took a piece of drill rod about 6" in length with a diameter of .159. I put the rod through the surface port, extending it past it. Inserted it in the drilled holes I made. I slid the surface port forward. It acted as an alignment gauge. What I did not like about the kit is the epoxy used to attach the surface ports and seal the surface crack. The working time to use it is way too short. I realize you need something that works fast to hold the ports in place. The bottom line is, did the repair work? There has to be a heavy downpour of rain or after winter with a spring thaw to find out.

The urethane injection kit proved user-friendly following the provided instructions and instructional videos. The epoxy scent, contrary to some claims, was tolerable. Managing an 8-foot, 1/4-inch-wide crack posed a challenge as the epoxy quantity provided was barely sufficient, resulting in minor leakage at some ports. Despite the inconvenience, using a towel mitigated the mess. Almost exhausting the urethane, a larger kit might be advisable for longer or wider cracks. While the effectiveness remains to be seen, considering the outcome, a repurchase is likely, opting for the 20-foot kit for larger fissures.

The website lets you use different billing and shipping addresses, but the product didn't ship on time. I called them and they mentioned they thought there might be fraud due to the address difference. Still, they charged my card without asking about the addresses. I reached out a week after buying. If using different addresses is an issue, they should not let it on the website and make phone orders necessary.

I bought LastISeal, CrackWeld, and Universal Concrete Cleaner a week ago. All arrived on time. LastISeal was easy to use, dried in 2 hours. Concrete Cleaner is pricey. CrackWell works well but might not match your concrete. Would I buy again? Yes! Considering using it on other parts of my property. All worked as promised.

Their eflorescence cleaner has small odor. It works well at fixing calcium bleeding through concrete block. I tried strong vinegar, it didn't work. Years ago I tried muriatic acid which worked about the same as RadonSeals product- but the smell was horible. I ran short on this job, so I ordered another gallon- it works.

The ordering process was straightforward, and the instructions proved successful in significantly lowering our radon levels by sealing the crack. I'm impressed with this product's efficacy and will rely on it for any future requirements.

I've made multiple orders in the past year, and I'm impressed every time. I'm planning to purchase more in the near future. I also happily recommended your products to our pool contractor. Your quality stands out.

On-time delivery, actually arrived within two days to Florida... The product's seal was easy to apply, but I'm still waiting to see how effective it is.
