Judy - "We applied this to a crack in our basement. It is the best thing we have found for sealing a crack in a wall. Would definitely recommend this for problem in basement wall!"
PSC- "Worked great would purchase again."
Eric Rivera - "Arrived on time, worked great for intended purpose. Only needed to be applied one in basement for a leak, easy to use, adhesive holding great, worth every penny."
Tea - "Parents’ concrete bi/level four foot wall had a big crack when wall was opened up due to buckets of rain water coming in during multiple rain days. We used this product and if you watch the video and do exactly as it says you will be successful. Make sure that you have enough epoxy product if your crack goes all the way through the concrete. They needed three tubes for four feet. Not sure if it will work as it hasn’t rained enough.
R.E. - GREAT PRODUCTS!
Dave L - "If you need to structurally fill a crack in a concrete wall, this is exactly the right product to use. I recommend this product and would use it again."
Maria A . - "This product goes on thicker - Whether small or large cracks, this mixture of A & B works well. It is thicker but still goes on cement walls, floors indoors or outdoors area of concrete. Heads up! This product is not made to pour as some products do."
ed - "Works as expected - I ordered this to apply on a 1/4" crack on the exposed foundation in my garage. The crack runs through the entire wall which is about 1' high. I covered the rear of the wall with cardboard so that the epoxy would not leak out the back. I inserted 3 of the injection ports into the crack and covered the rest with cardboard. Using my caulking gun I injected the epoxy mix into the ports starting from the bottom port. The smell from this is pretty strong so I had a fan blowing air across my work area. I let this sit for a couple days before removing the carboard. The epoxy worked in filling the crack and feels solid."
Robert - "Easy to use and it worked so far."
Lesa - "It sealed my wall great."
Logan - "Product was great overall. Used for crack in my foundation that was leaking, got a couple inches of rain days after the repair in the basement. Stay dry."Cecilia - "Good for small jobs, holds good and since instructions are simple you can fix everything yoursel. I highly recommend."
Judith - Worked very well. Would definetly buy again."
