Can Sodium benidite act as a water barrier?

Answer 1

I'm from the old school of reason. To think that injecting chemicals into the ground around the foundation to stop water from leaking into the basement is kind of hard to believe. In most cases the reason water is entering the walls in the first is deterioration of the foundation walls on the exterior. It would seem that, all though more expensive.....The best way to repair and solve a water intrusion problem would be to excavate the material from around the leaking section of wall, adhere some sort of repair material like cement, probably hydraulic cement or some other strong water proof application material, seal it with tar or some kind of foundation sealer and back fill. If you want to get real fancy you can drap a piece of rubber over the sealer and when you back fill the rubber will embed itself into the wall. This type of fix gives you a rebuilt wall along with a sealed wall at the same time. The old saying goes..."If it sounds to good to be true" it probably is.
