What is a perimeter drain?
A perimeter drain is something that all houses have, and it is designed to prevent water from seeping into your basement.

It then carries the water away from your house, so it is less likely to seep in through your basement walls. You often hear it referred to as ‘weeping tile.’ Many years ago, actual clay tiles were used to divert water, and the name has stuck even though tiles are no longer used, but rather perforated pipes. It is also sometimes referred to as a French drain, because this drainage method was popularized by Henry French of Concord, Massachusetts back in the 1800’s.
