Interior Basement Drainage

An interior basement drainage system is designed to manage and redirect water that may enter a basement, preventing issues such as flooding, water damage, and mold growth. Here's a description of the key components of an interior basement drainage system:

  1. Perimeter Drainage Channel:
    • A trench is excavated along the interior perimeter of the basement floor.
    • A perforated drain pipe, often made of PVC, is placed in the trench to collect water.
    • The pipe is covered with a layer of washed gravel to allow water to flow easily into the system.
  2. Sump Pump Pit:
    • A sump pump pit, or basin, is installed at the lowest point of the drainage system.
    • The perforated drain pipes from the perimeter channel direct water to the sump pump pit.
  3. Sump Pump:
    • A sump pump is installed inside the sump pump pit.
    • When water accumulates in the pit, a float switch activates the pump, and it pumps the water out of the basement and away from the foundation.
  4. Check Valve:
    • A check valve is typically installed on the discharge pipe from the sump pump.
    • It prevents water from flowing back into the sump pump pit after the pump has expelled it.
  5. Backflow Prevention:
    • Some systems include a backflow prevention device to ensure that water from the exterior drainage system doesn't flow back into the basement.

How It Works:

installation of a tailored drainage system for efficient water management.
  1. Water Collection: When water enters the basement, it is directed to the perimeter drainage channel.
  2. Perforated Pipe:
    • The perforated drain pipe collects the water from the channel.
    • Gravity helps move the water toward the sump pump pit.
  3. Sump Pump Activation:
    • When the water level in the sump pump pit rises, the float switch activates the sump pump.
    • The sump pump pumps the water out of the pit and away from the foundation.
  4. Discharge:
    • The water is discharged through a pipe that extends from the sump pump to the exterior of the home.


  1. Prevents Basement Flooding: By effectively managing and redirecting water, interior drainage systems help prevent basement flooding.
  2. Reduces Moisture: By controlling water infiltration, these systems reduce moisture levels in the basement, minimizing the risk of mold and mildew.
  3. Protects Foundation: Proper drainage helps protect the foundation from water-related damage and soil erosion.
