We also excels at waterproofing foundation walls and sunken areas. A real basement must be fixed from the inside out, not just where the leak first becomes noticeable. For more than 25 years, we have performed various types of waterproofing (both commercial and residential). We perform an inspection, assess the issue, determine the best course of action for your sunken basement, and then start our water-resistant basement service to ensure flawless results at reasonable prices
