TrenchDrain

Trench Drain
The trench drain is for exterior doorways, stairways and garage doors.
If you have a doorway or stairway that leads to the outside or a garage, you'll want to have a trench drain installed in front of it.
A trench drain is like a half round pipe with a grate that fits snuggly on top of it. The grate is flush or slightly below the floor to catch any water that leaks from the outside, causing a wet basement. The drain is the perfect solution if you have a less than watertight bulkhead door or entry way.

Protect from leakage now or later
This way you are protected against leakage from a hatchway door, bulkhead door, sliding door or even a garage door. Even if your door doesn't leak now, with the right snow/slush/or heavy rain conditions, it can.
