    WaterGuard System in Hastings-on-Hudson, NY

    This basement had a constant water problem that would disrupt the functionality of this home. Tired of a wet basement, the homeowner decided to call Connecticut Basement Systems for a permanent solution.  The solution to this basement was to install a full perimeter WaterGuard system to prevent water to enter the area. This system is installed around the perimeter of the basement and will collect water internally and channel it to the sump pump. The sump pump will then discharge the water away from the home. CleanSpace liner was also installed on the half wall around the basement to prevent any moisture or water from the coming through the walls. (You can see the liner in the after photo) This is exactly what the homeowner wanted and was pleased with the results!
