# Its Importance and Benefits of an Under Deck Drainage System When it comes to protecting your deck from water damage, one of the most critical — yet often overlooked — features is an efficient under deck drainage system. A well-designed drainage setup prevents costly water infiltration, rot, mold, and structural instability, ensuring your deck remains safe, durable, and beautiful for years. ## What Is an Under Deck Drainage System? An under deck drainage system is a carefully engineered network designed to channel water away from the area beneath your deck. This system typically includes strategic perforated pipes, gravel trays, weep holes, and grading around the deck base. Its purpose is simple: to collect and direct water away from the deck, preventing pooling and moisture buildup.
