Video shows how to repair a crack in smooth concrete wall. RadonSeal crack injection kit for homeowners or contractors is complete you only need a caulking gun. Fills the entire crack with expanding urethane or epoxy. Then, just peel off the surface sealer for a clean, bare surface. For permanent, professional-quality repair of leaky basements.
Amazingly simple instructions. I can see this being used on foundations that are 15 years plus old with no development occuring in the immediate surrounding areas. If a new home or in an area of development consult an engineer for shifting foundation issues as the crack may indicate larger forces at work. Great job!

Settling cracks often appear much sooner than 15 years.

My entire foundation is cracked, horizontally, should this work for that as well?

Horizontal cracks are often caused by structural issues and you should consult a structural engineer first if there are other measures needed as well. In any case, you will have to stop or prevent water seepage through the crack. Crack injection does that. The standard kit fills the crack with expanding urethane foam, allowing for some natural movement of the concrete. If the crack is dry inside, injecting epoxy will give it structural strength.
