Garage in partial basement
We have a large walkout basement. Only 1 side of the basement is actually underground. On that side of the basement we have a one car garage. I've noticed when It's humid outside and I leave the garage door open that wall will start looking wet along the areas that are actually underground. Is it possible to insulate that wall and stop the condensation? If so, what would be the best insulation and proper method for solving the problem?
