Soil Stabilization - Construction & Construction Materials - Geotechnical

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 subgrade below.  The thickness of the overall framework and subbase can be decreased with equivalent or greater structural integrity.
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.
