WHY DO SOME WALLS NEED REINFORCEMENT?
Geo-grid creates a stable mass that allows walls to be designed and constructed to much greater heights than simple gravity walls because it stabilizes the soil behind the wall face. Geo-grid is used to impart tensile strength into soil structures, allowing such structures to be built taller and steeper than the soil alone would allow, or for building on soils with bearing capacities insufficient for supporting a proposed structure. Geo-grid can be thought of as performing in the soil in much the same way that reinforcing steel bars perform in the concrete. The amount of geo-grid required in a retaining wall structure, and the spacing of layers of geo-grid in the retaining wall structure, must all be determined by the specific design considerations (wall height, surcharge loadings, soil, etc.) of the individual project (see Reinforcement).
