The TrenchDrain™ resembles half of a basement drainage pipe, with a grated opening fitted snugly on top. The grate is flush or slightly below the floor, eliminating any tripping hazard. It is uniquely designed to span doorways, hatchway entrances, and similar entryway doors. Any water passing over the drain is collected through the openings and redirected to your sump pump.
