Which sealant/epoxy to use for moisture that's causing mold?

[Race Ostler]

I recently purchased a home built in 1915. There is a cellar room in the basement that has a moisture issue. The room has brick flooring and stone walls. There is a well 15 feet away and water seeps through making the brick and stone damp which creates mold.

It would be expensive to dig up the exterior lawn to fix it from the outside. I am thinking about coating it from the inside, thereby blocking mold. I wanted to see if anyone out there in the BP world had any suggestions as to the type of sealant/epoxy I could use for this
