TL;DR
Interior drain tile is a perforated pipe system set in washed gravel inside a trench cut around the basement slab perimeter, collecting water that seeps at the cove joint and wall base and carrying it to a sump pump. Installed with a dimpled vapor gap at the wall, it relieves the hydrostatic pressure that pushes water through floor-wall joints, and unlike exterior excavation it works in finished, landscaped homes year-round.
What it means
Interior drain tile is a perforated pipe system set in washed gravel inside a trench cut around the basement slab perimeter, collecting water that seeps at the cove joint and wall base and carrying it to a sump pump. Installed with a dimpled vapor gap at the wall, it relieves the hydrostatic pressure that pushes water through floor-wall joints, and unlike exterior excavation it works in finished, landscaped homes year-round. It manages water rather than sealing it out, so pairing with wall crack repairs and grading fixes remains part of the scope.
