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 v. Soilless Cover Systems
