I had major water problems and dampness on my foundation walls and basement floor, in many areas through out the basement and cracks in my foundation walls. Keller fixed my basement by digging from the outside and sealed my foundation walls and installed new drainage around the entire perimeter. My walls are bone dry and my basement floor too after Keller completed their system. I used to have over 5" of water on my floor after the floods in 2009. I cannot say how happy I am about the work and the professional crew that completed my job.
