A geogrid is geosynthetic material used to reinforce soils and similar materials. Geogrids are commonly used to reinforce retaining walls, as well as subbases or subsoils below roads or structures. Soils pull apart under tension. Compared to soil, geogrids are strong in tension. This fact allows them to transfer forces to a larger area of soil than would otherwise be the case.

A structural member such as a geogrid may engage (e.g. frictional) the container and extend therefrom to engage and support a structure such as a retaining wall, earthen slope, etc. Accordingly, the container may function as an anchor to the structure. Due to the containment provided by the container, the physical characteristics of the earthen material therewithin become less important. Thus, low quality fills such as fine-grained fill or fill with a high moisture content may be used in structural applications. If desired, more than one container and structural member may be incorporated. Containers may be stacked, positioned side-by-side, positioned end-to-end, etc. Structural members may be incorporated as needed to adequate support the structure.
