Types of Soilless Cover Systems

2

Artifical Turf Cover System

  • No erosion
  • Great aesthetics
  • Higher initial cost than exposed geomembrane
  • Lower long-term cost than soil cover system

High Performance Green Exposed Geomembrane

  • No erosion
  • Good aesthetics
  • Lower initial cost than artificial turf or soil cover
  • Lower long-term cost than soil cover system

Conventional Soil Cover Soilless Cover Import of cover soil Yes No Import of top soil Yes No Veneer stability Yes No Drainage geocomposite needed Yes No Watering grass in perpetuity Yes No Fertilizing grass in perpetuity Yes No Repairing erosion in perpetuity Yes No Mowing grass in perpetuity Yes No Increased airspace No Yes Carbon footprint Higher Lower Warranty of cover material None 30 years Long-term cost of ownership Higher Lower
