Invisible Structures

Grasspave2

Grasspave2 porous paving allows you to park, drive, walk, ride, or lounge on a beautiful grass surface. It performs the functions of asphalt or concrete pavement, but with the aesthetics of a lawn-all while enhancing the environment.

Grasspave2 is a structure, which provides incredible load bearing strength while protecting vegetation root systems from deadly compaction. High void spaces within the entire cross-section enable excellent root development, and storage capacity for rainfall during storm events. For example, a 13-inch cross-section (one inch Grasspave2 with sand and a 12-inch base course) can store 2.6 inches of water-13 inches X approx. 20% void space. Stormwater is slowed in movement through and across Grasspave2 surfaces, which deposits suspended sediment and increases time to discharge. Suspended pollutants and moderate amounts of engine oils are consumed by active soil bacteria, which are aided by the system’s excellent oxygen exchange capacity.

Competitive Advantages:

• Attractive (real) grass surface
• Easily installed large rolls
• Multiple-use surfaces
• Lower installation cost
• 92% void space for healthy turf
• Flexible to resist freeze/thaw and to traverse contours
• Load bearing- 5,721 psi (14,470 kPa) compressive strength

Environmental Benefits:

• Made from 100% recycled plastic
• Urban heat island mitigation
• Air-conditioning effect (transpiration)
• Encourages tree growth and preservation
• Reduces erosion and soil migration
• Airborne dust capture and retention

Stormwater Benefits:

• Filters pollutants
• Recharges groundwater supply
• Reduces runoff volume, rate, and temperature
• Reduces non-point-source pollution
• Stormwater detention in cross-section

Applications Include:

• Overflow and event parking
• Fire lanes
• On-street and employee parking
• Pedestrian access and golf car paths
• Grass driveways
• Road shoulder reinforcement and parking
• Infiltration basin/swale reinforcement
• RV and boat access road and parking

Gravelpave2

Gravelpave2 porous paving allows you to park, drive, walk, or ride on a beautiful decorative gravel surface.

Gravelpave2 is a structure that provides heavy load bearing support and true containment of gravel creating a porous pavement surface with unlimited traffic volume and duration for parking. The system can be used for storage and filtration of rainwater. For example, A cross-section with a 12-inch deep base course (at 20% void space) and the one inch high Gravelpave2 structure (at 35%) would store 2.85-inches of rain. Although bacteria concentrations are lower than with Grasspave2, polluted runoff and vehicle drippings are consumed prior to reaching the water table.

Competitive Advantages:

• Unlimited traffic on porous surface
• Attractive gravel or decorative stone surface
• Easily installed large rolls
• Multiple-use surfaces
• Integrated geotextile fabric
• Flexible to resist freeze/thaw and to traverse contours
• Load bearing- 5,721 psi (14,470 kPa) compressive strength

Environmental Benefits:

• Made from 100% recycled plastic
• Urban heat island mitigation
• Air-conditioning effect (transpiration)
• Encourages tree growth and preservation
• Reduces erosion and soil migration
• Airborne dust capture and retention

Stormwater Benefits:

• Filters pollutants
• Recharges groundwater supply
• Reduces runoff volume, rate, and temperature
• Reduces non-point-source pollution
• Stormwater detention in cross-section

Applications:

• Parking lots
• Driveways
• Multiple-use trails
• Golf cart paths
• Infiltration basin/swale reinforcement
• Boat ramps
• RV and boat access road and parking
• Fire lanes and maintenance/utility access
• Road shoulder reinforcement and parking

Rainstore3

Rainstore3 is a plastic structure used to store stormwater underground. Made from injection molded plastic, a single panel contains 36 vertical columns and exceeds H-20 loading. This allows the construction of driving areas, parking, lots, or other small structures above the system. Built-in compression fittings allow units to be easily stacked to a variety of depths from as little as 4 inches to as deep as 8.2 feet.

The Rainstore3 modular system is more efficient at storing and recharging water than arched chambers and corrugated plastic or metal pipe. Rainstore3 is less expensive than concrete vault chambers.

Competitive Advantage:

• Multiple-use areas-storage with surface development
• 94% void space
• High strength, H-20 Loading
• Stackable from 10cm to 2.4m in 10cm increments
• Lightweight-high-impact polypropylene
• Unique configurations with modular units
• Useful in high water tables
• Quick and efficient installation
• No stone requirement

Environmental Benefits:

• Made from 100% recycled plastic
• Reduced site disturbance
• Reduced odor and pest breeding

Stormwater Benefits:

• Recharges groundwater
• Reduces non-point-source pollution
• Stormwater capture and reuse (harvesting)
• Reduces runoff volume, rate, and temperature

Applications:

• Underground stormwater storage
• Detention or retention systems
• Water harvesting for irrigation
• Stormwater harvesting for toilet flushing and/or other grey water applications

Aquashield

Aqua-Swirl
Floatable debris, oils, and grease enter the storm drain. Contaminated water enters the Aqua-Swirl via the conveyance storm pipe. Vortex separation is used to remove the gross sediment, floating debris and free-oil. Vortex, a swirling pattern, enhances removal efficiency of pollutants. A combination of hydrodynamic and gravitational drag forces encourages the floatable contaminants to migrate to the center where velocities are lowest and allows dynamic settling of solids at the bottom of the chamber. The Aqua-Swirl is constructed of durable, lightweight, and corrosive resistant high density polyethylene (HDPE).

• Highly effective sediment removal
• Validated TSS removal > 80%
• Reduces floating debris and free oil

Aqua-Filter
Fine sediment, nutrients, oils, and grease enter the storm drain. Vortex separation removes gross pollutants prior to water entering the filtration chamber. Filter media removes fine sediment, nutrients, and oils to achieve a higher water quality. Aqua-Filter operates without any moving parts or valves. Its modular design utilizes effective swirl technology of the Aqua-Swirl as pretreatment in conjunction with a filtration chamber to refine or polish the stormwater over a bed of media removing fine sediment, nutrients, petroleum hydrocarbons and heavy metals prior to discharge into sensitive receiving waters. The Aqua-Filter is constructed of high density polyethylene (HDPE) and can be installed easily without heavy machinery

• Verified results targeting TSS, TPH, nutrients, and metals
• TSS removals > 80% at 20/m
• Superior modular design

Aqua-Guardian
Surface runoff from paved areas such as parking lots, streets, and bridges enter the storm drain. Contaminated water enters the Aqua-Guardian catch basin via curb inlet or surface grate. As the storm continues, water flows through a locking filter screen standpipe that disperses over filter media where fine sediment, petroleum hydrocarbons, nutrients and heavy metals are removed before exiting the catch basin insert through a perforated base plate. Proven point-source protection for sensitive receiving waters. The Aqua-Guardian is constructed of HDPE and stainless steel for easy installation.

• Wide range of pollutant removal
• Eliminates pollution at the source
• Contaminant driven filter media
