We have a dirt floor in the basement of our 200-year-old house. We have a very high water table, so our basement is frequently wet. We do have a sump pump which elimnates most standing water but the water comes up from below and so the dirt stays damp. We would like to get an estimate on waterproofing our basement.

I have about a 3 foot long crack about 3/8" wide in my basement foundation wall that has a steady trickle of water during heavy downpours throughout the year and in the spring when the snow melts. Have had a leak near our chimney/foundation as well but major problem area is the crack.
