Foundation Support of HI Before & After
  • Flooding in Basement, Honolulu, HI
    Flooding in Basement, Honolulu, HI

    Flooding in Basement, Honolulu, HI

    Iris K., a resident of Honolulu, had waterproofed her crawlspace in the past which included a french drain. However, she was still experiencing flooding. She contacted Foundation Support of Hawaii to come out and take a look.    After her appointment with Kevin she proceeded with his suggested solutions to waterproof her home from the flooding. Iris had a WaterGuard sub-floor drainage system, a SuperSump pump system, a CleanPump Stand and WaterWatch alarm system installed in her basement. The SuperSump drains water from the WaterGuard and from below the basement floor and discharges it outside of the basement. The WaterGuard is what intercepts the water at the perimeter of the basement or crawlspace. The WaterWatch alarm system alerts the homeowner to pump or power failure before the water rises above floor level.    Iris is glad she went with these easy to clean and maintain installations after dealing with the previously ineffective french drains. She feels good knowing her basement will be clean and dry now.
