Looking for advise. I have an old farm house that is need of foundation help. Not sure what to do. I recently had Everdry, a company that repairs foundations via some form of sealinig, take a look and estimate repairs. They pointed out some damge due to water being trapped in the walls- turned the masonry to a dust like state. I'm not sure if sealing is the correct option or is there another option. I am located on a hill so I do not have the problem of ground water, water table rising. Its just during heavy rains and snow melting that it comes in the walls.
