Sheet drains are advantageous because of their easy and inexpensive transport and installation. Because of their thin and lightweight construction, sheet drains require less excavation for installation than aggregate systems. In addition to ease of installation, the thin and lightweight design of sheet drains also allows a higher flow capacity than several feet of stone. High collection capacity makes sheet drains a more efficient solution than sub-surface drainage systems. Due to the reduced seepage of water through the drain, sheet drains also extends the life expectancy of waterproofing systems.
