Clark Companies has been installing subsurface drainage systems for many years on both natural and synthetic turf fields and has used all types of systems. When we started using the Hydraway Subsurface Drainage System, we were immediately impressed by the ease of installation and high compressive strength of the product. These features, coupled with an unsurpassed industry water in-flow rate is why we continue to choose the Hydraway Subsurface Drainage System over the competition.
