What is the purpose of a perimeter drain in a basement and how does it help in managing water infiltration and drainage issues?

A perimeter drain in a basement is designed to collect and redirect water away from the foundation of a building. It helps manage water infiltration and drainage issues by preventing water from seeping into the basement, reducing the risk of flooding and water damage. The drain system typically consists of a series of pipes and gravel that channel water away from the foundation, keeping the basement dry and preventing structural damage.
