Load Support Applications

When filled with granular material, StrataWeb forms a composite 3-dimensional structure that substantially increases the load bearing capacity of the underlying subgrade. Each cell confines the soil preventing lateral spreading and increasing base course stiffness. Both soil interaction with the cell walls and passive resistance developed between adjoining cells, increases vertical shear resistance of the soil. The result is a structure that acts like a stiff soil beam, and in effect, imparts an apparent cohesion characteristic to a wide variety of infill materials.

The "zone" of base course confinement is much greater than conventional geogrids so the stabilizing capacity is far greater. One of the most important benefits of StrataWeb over geogrids is the ability to utilize inferior fill such as quarry screenings, sand, on-site granular soil, recycled asphalt or crushed concrete. Even with inferior fill it is possible to reduce base course thickness by as much as 50%.
