In the civil engineering discipline, the challenge of constructing durable and cost-effective roadways over problematic soils is a common yet complex issue. High-plasticity clay subgrades, known for their susceptibility to moisture and subsequent weakening, pose significant hurdles. Traditional methods of soil excavation or chemical treatment can lead to increased costs and project delays. However, with the increased utilization of geogrids, particularly the TerraGrid® TXG-7, a cost-effective and reliable solution, engineers have a trusted option to keep their projects on track.
