Sand Channel Greens designs and installs sub-surface drainage systems for new and renovated sports fields and golf courses. Our narrow channel, high-intensity drainage systems:Are more resistant to settlingAnd, provide more rapid rain recovery.As a result, Sand Channel Greens fields have a significantly greater number of play days and reduced maintenance. Each system consists of a network of interconnected channels filled with a high performance drainage medium. The network is designed to collect surface water and carry it away. The company's systems implement the concept of vertical bypass drainage. The combined effects of gravity, capillary action and adsorption move water into and through the network of channels, effectively bypassing the surrounding soil.
