WINDOW WELL DRAIN INSTALLATION

Keep Storm Water Out of the Basement

Window wells can collect large amounts of storm water. A properly designed window well drain can direct collected water into an approved drainage system rather than allowing it to enter around the basement window.

Collect Capture water accumulating inside the window well.

02

Redirect Direct collected water toward an appropriate drainage system.

STAIRWAY DRAINAGE

Basement Stairways Can Collect Significant Rainwater

Exterior basement stairways can collect large amounts of rainwater. A stairway Speedy Drain system can help capture that water and connect it to the basement drainage system.
