Groundwater often reaches a sump basin through drain tile installed around the foundation. As the water level rises, the float activates the pump and sends that water through a discharge pipe away from the building. This cycle helps keep water below the basement floor.
Heavy rain, rapid snowmelt, a high water table, and sudden surges of stormwater can all increase the amount of groundwater around a Milwaukee-area foundation. A properly sized pump provides an important layer of protection, but it doesn’t correct every source of basement water. Foundation cracks, poor grading, clogged exterior drainage, and sewer backups may require separate solutions.
