Environmental Benefits
System Element
Environmental Factors
Sub-base Layer
Less removal of existing base material saves fuel and disposal impacts, potentially reduces movement of 2700 yards of material for a standard field.
System can use recycled concrete as a stabilization mechanism.
Drainage Layer
Drainage mat is composed of recycled material and can be used for two cycles of turf.
Drainage mat can be recycled to alternative uses. Use of mat versus aggregate eliminates movement
of 3000 tons of rock. Installation of mat versus construction of base
eliminate the environmental impact of heavy construction equipment constructing base.
Reduction in the use of non-renewable aggregate resources

INNOVATIONS IN STORM WATER MANAGEMENTFOR SYNTHETIC FIELD APPLICATIONS
SPORT TANKWATER MANAGEMENT STRUCTURES
Sport Tank Water Management Structures are a patented system that provides a more efficient alternative to traditional storm water management for synthetic turf applications.
Unlike a natural field, synthetic fields typically include a significant drainage and storage system constructed with natural aggregate below the turf.
Utilizing Sport Tank within the synthetic turf system, storage of water runoff is maximized by the void space created by the structural modular unit.
Applications: Storage & Reuse Retention & Filtration Detention
SPORT TANKWATER MANAGEMENT STRUCTURES
Sport Tank Advantages
Cost Effective—Ideally suited for perimeter trench installation in synthetic turf applications
High-volume storage within a small footprint: 95% void internal area Modular Design: Can be placed in any shape to efficiently use space
and stackable in depths of more than 7’ High Strength: May be used under parking lots and roads Increased Infiltration: Outer shell is 90% open thereby increasing
ground water recharge Easy Transportation: Can be supplied un-assembled to reduce
delivery cost Lightweight and easy to install: Can be put in place by hand Permanent and Maintainable Storage Volume: All storage volume is
isolated inside a geosynthetic envelope and has no reliance upon non-sustainable, temporary, or assumed void space in aggregate backfill
Sport Tank promotes a localized storage area so that water can infiltrate into the subsoil at a controlled rate for ground water re-charge. The system is designed to capture surface water through infiltration and then filter the water for recharging into water table.
Sport Tank can be designed to temporary store storm water. In a detention system, the storm water is stored then discharged over time so runoff does not exceed the allowable discharge rate. Engineering a detention system for a synthetic turf field is maximized with Sport Tank while utilizing a minimum of the required space.
Sport Tank promotes a clean water storage collection structure under your synthetic turf field. Sport Tank maintains 100% of its capacity inside the structure, thereby eliminating the use of aggregate storage. This completely maintenance-free system, provides maximum storage in limited space, and is the better way to store storm water.

ESS Sport Flow HF & New Meadowlands Stadium
SPORTFLOW INSTALLED AT THE NEW MEADOWLANDS STADIUM, HOME TO THE NFL JETS & GIANTS
The New Meadowlands Stadium is the newest NFL stadium to incorporate a synthetic turf athletic system. ESS Sportflow was selected to ensure the the project requirements are satisfied, excellent drainage, great compressive stiffness to support traffic, and high tensile strength for increased reinforcement. Placed under the aggregate layer, ESS Sportlfow ensured excellent drainage and was able to reduce the overall depth of the excavation and aggregate layers.
This new stadium will be the home field for the New York Giants and the New York Jets, the first facility built specifically to accommodate two National Football League teams. Additionally, the multi-purpose stadium will be used for concerts and other entertainment and sports activities. The stadium is slated to open in the 2010 season.

ESS SportGrids/TurfGrids
ESS Sport Grids are engineered to meet the unique requirements of your project.
These synthetic fibers are engineered and manufactured for both synthetic and natural turf to reinforce and stabilize soil.
They are manufactured from polypropylene and are non-toxic to plants, animals, and humans.
These fibers are incorporated into the soil profile at a depth of 4 to 6 inches where they reinforce and enhance the soil properties. They are designed to increase the shear strength of the soil while not effecting permeability.
Product Advantages:
Safe and Non-Toxic
Provides a consistent athletic surface
Easy to install, mix, and/or grade
Resist damage
Promote strong grass growth
Resists the divots, pits, tracks and marks

ESS Geogrids
ESS offers a wide selection of geosynthetic geogrids that are engineered to improve the performance of weak subgrade in athletic fields.
While reinforcing and increasing the stiffness at the base the synthetic or natural sport field, the geogrid openings interact with base materials, confining them and preventing lateral dispersion and improving structural performance of the subgrade.
Product Advantages:
Soil stabilization and Base Reinforcement
Increased separation between the subgrade and fill material
Prevent lateral dispersion of base materials
Improves structural performance
ESS Geogrids & The Perimeter Drain
Compacting rounded, clean drainage stone in the perimeter drainage ditch is a challenge to most contractors on synthetic fields.
The potential for the stone to displace under load causes the lines to move, especially during the infill process. Placing a layer of geogrid on top of the perimeter trench just below the turf or synthetic aggregate system helps to reduce this potential problem. The open area of the geogrid allows for the stone to interlock and resist lateral displacement through confinement.
The stiff, rigid geogrid, through lateral constraint mechanism, provides a nice, stable platform for the overlying layers without reducing drainage characteristics of the aggregate.
