The uses of geosynthetics in civil engineering are relatively well-defined according to their functions. There is still, however, an inclination to use traditional methods over geosynthetics. The use of high-strength geogrids is not as widely used as lower-strength geogrids which are commonly applied in civil engineering applications. Zimbali Lakes Resort was a development that required earthworks conducted before the construction of the facilities. The initial construction required high-engineered fills that were designed to reach a height of up to 15m. The excessive load projected instability, and the high-water table necessitated the requirement for control measures. Reinforcement was required to increase the shear strength of the soil before it can support the self-weight of the fill. High-strength geogrids were used to restrict the vertical displacement of the fills by preventing base sliding, controlling differential settlement, and protecting the embankment against internal and global stability failures.
Key words: Geosynthetics / Geogrid / Reinforcement
