Our Applications

Soil Stabilization

Problem: Poor load-bearing soils pose a significant problem for transportation and construction needs. Unpaved areas, such as access roads, paths, parking lots, driveways, etc can be highly vulnerable to near-surface shear failure and rutting, especially in moist conditions or areas with higher expected loads. Typically, engineers bridge over weak soils with rigid structures such as thick, reinforced concrete for roads and highways. However, such techniques are prohibitively expensive and inordinately difficult to install. The poorer the quality of the sub-base and the heavier the expected loads, the greater the amount and better the quality of support required.

From an environmental viewpoint, hard-pavement, as an impervious surface, is far more harmful for the environment than a porous surface. If the environment is a primary concern for the construction application, then a pervious solution should be considered.

Solution: EnviroGrid® provides a direct, cost-effective solution. The high-strength cell walls maintain the shape and integrity of the structure, allowing for heavy equivalent axle loads without fear of lateral movement of the fill material. The cellular design of EnviroGrid® also distributes the loads to an extended area, thus reducing the stress to the grid itself as well as to the sub-grade below. The thickness of the overall framework and sub-base can be decreased with equivalent or greater structural integrity.  In most cases the EnviroGrid® solution can reduce a typical cross section to 1/3 or the original design.  

Using EnviroGrid also allows for lower quality aggregates found locally, eliminating the need to import better or more material. Compact sections of EnviroGrid filled with sandy soil can thus replace truckloads of crushed stone or other granular fill or even asphalt or concrete.

If porous pavement for natural groundwater drainage is desired, EnviroGrid® allows for the use of permeable aggregates while maintaining sufficient weight-bearing capacity.

Slope Erosion Control

Problem: Soil particles are susceptible to being detached and carried away with concentrated runoff streams, forming rills and gullies that grow with time. The slope integrity is diminished, eroding the slope face and becoming a larger environmental and safety issue.

Slopes steeper than the natural angle of repose for the slope materials require additional protection measures, as are slopes subject to more severe hydraulic stresses.

Solution: EnviroGrid® effectively holds slope cover materials in place, thus reducing the potential for erosion. Cell walls check the runoff streams associated with rainfall, keeping the overall system intact. The infill material also rests within individual cells, allowing for much higher angles of repose.  The EnviroGrid® geocells can be used in slopes as steep as 70° and secured in place by our EnviroClip twist anchors or our tendon system.   

EnviroGrid® filled with soil promotes vegetation as well as another source of reinforcement and natural aesthetics. Overall effectiveness of the system is increased with the plant roots integrated into the grid system.  The EnviroGrid® system can also be filled with rock or concrete without the need of wood forms or rebar reinforcement.

Channel Wall Protection

Problem: Channels are often times subject to debilitating erosion due to the water contained by the channel walls. Depending on the velocity of the water flow and the frequency and degree of storm water runoff, severe hydraulic stresses upon the channel can pose significant dangers to the system.

Multiple considerations are necessary to achieve a safe, environmental, and durable channel system:

– Not only must the system be resistant to erosion, but stable under the slope geometry and hydrostatic uplift forces.

– The channel walls must also be somewhat flexible in order to ensure integrity in the face of localized deformations from seasonal factors and sub-base void formation. However, the system must also be sturdy and durable enough to avoid degradation and uplift from the hydraulic forces present.

– System permeability is desirable in some situations to allow natural drainage. A pervious channel lining can relieve hydro-static uplift forces, thus stabilizing the system.

Standard soil and grass linings face the danger of erosion from extended water flow. When channels are lined with loose aggregate, even low to moderate forces can gradually remove particles. Poured concrete walls can only perform effectively with construction joints to avoid rigidity and to lessen the dangers of compromise from base material displacement.

Solution: EnviroGrid® can be laid directly on the slope and properly anchored. Based on the velocity of the flow and duration, the EnviroGrid® can be filled with angular rock (up to 10 fps, 3 m/s), vegetated soil (up to 20 fps, 6 m/s) or concrete (20 fps, 7 m/s and higher). A single panel can be filled with different types of material so that it can withstand hydraulic energy as well as providing an aesthetic look.  Geo Products also offers the needed anchoring for the system’s integrity.

Retaining Walls

Problem: Retaining Wall structures are growing ever more necessary as construction is forced to deal with rough terrain, steep slopes, and embankment reinforcement. Changes-in-grade present obstacles for roads and other development requiring flatter, more usable land. Most current types of retaining walls are made of cast-in-place, steel-reinforced concrete walls whose virtue is based entirely upon its internal strength and rigidity. However, these cantilever walls are expensive, vulnerable to cracking from high stress situations, and unattractive in the environment.

Solution: EnviroGrid® retaining walls can be constructed quickly and cost-effectively for almost any situation where a rapid change of grade is needed, whether to hold back a cut slope or to extend and fill a slope steeper than the soil alone would allow. This gravity retaining wall works by stacking multiple layers of EnviroGrid®, which stands by virtue of its weight and can be easily constructed with local aggregates. In addition, gravity retaining walls have a degree of flexibility that allows them to be constructed over variable foundation soils without loss of structural stability.

The large frictional resistance between the filled layers creates a single composite structure. The cell walls confine the infill materials, allowing extra imposed loads and eliminating erosion damage. The outer exposed area of the wall can be vegetated, providing a natural looking but useful structure in place of a concrete wall.

Geomembrane Protection

Problem: Geomembranes are the primary way to contain fluids. Even though a geomembrane liner is impermeable it is very susceptible to punctures.

For decorative pond applications a geomembrane liner does an excellent job containing water but the exposed black material is not an acceptable option. 

Solution: EnviroGrid® cellular confinement system is the safest way to protect a geomembrane liner. For industrial applications with the use of a non-woven fabric, the EnviroGrid® can be placed directly on the liner and filled with stone or concrete. The EnviroGrid® becomes the form for the concrete without the need of wood forms, nails, steaks or rebar reinforcement.  

For decorative ponds the EnviroGrid® covers the unsightly black geomembrane and allows for soil fill that can be vegetated.
