French Drain Installation Around Foundation For Water Diversion
French Drain Installation Around Foundation For Water Diversion Of all the strategies available to keep groundwater away from a basement, a properly designed French drain is one of the most durable and effective. Unlike interior solutions that manage water after it has already reached the foundation, an exterior French drain intercepts groundwater in the soil and redirects it harmlessly away, before it can build hydrostatic pressure against the basement walls. Done well, the system lasts decades. Done poorly, it becomes a buried liability that homeowners pay to replace within five years. What separates the systems that work from the systems that fail? The answer almost always traces back to four engineering fundamentals: trench depth, slope continuity, fabric and gravel selection, and outlet design. Each of these is deceptively simple in concept and unforgiving in execution. This guide walks through the decisions that determine whether a French drain delivers on its promise o...
