What kind of drainage is necessary with synthetic turf fields?
Most sub grades for fields are constructed using aggregate material. Sometimes imbedded in the aggregate are flat drains leading into a perimeter drainage system that surrounds the field. In addition, many fields constructed inside of existing tracks also use a trench drainage system against the track. Most fields we construct today can absorb and evacuate water at a rate of about 16 inches per hour. There are other drainage systems used today in field construction. There is an airfield drainage system that employs a plastic grating system and a pond liner. There is also another system using a fabricated drainage material inserted under the playing surface. Almost all fields have at least a perimeter drainage system.
