Excavation consists of digging out all the dirt that sits by the walls down to footer level; replacing the footer tiles, sealing the walls, covering that with gravel and backfilling with soil to grade level.
Interior System
In this scenario, work is performed from the inside of the basement. The floor is opened next to the outside walls, and drain tile is installed and surrounded by gravel. The pipe is connected to a sump pump, which discharges the water.
