French Drain
A French Drain is a popular solution for directing water away from buildings and properties. Think of it as an underground water channel that collects and redirects water to prevent flooding and foundation damage. It's basically a trench filled with gravel and a perforated pipe that catches water and guides it away from problem areas. This is a fundamental skill in waterproofing and landscaping jobs, similar to other drainage solutions like surface drains or dry wells. When you see this term in resumes, it indicates hands-on experience with water management and foundation protection.
