Stabilization of Soil Using Polyurethane Resin Injection Technology

The use of ground improvement technology, specifically soil injection using polyurethane resin, has gained significant attention in the construction industry for foundation sediments. This technique offers various applications in infrastructure projects and provides advantages such as preventing settlement, improving load-bearing capacity, and sealing underground structures. Traditional methods for stabilizing weak soil conditions are often time-consuming, costly, and may not produce desirable results. Polyurethane resin injection presents an alternative that requires minimal excavation, penetrates fine cracks and voids, and enhances the mechanical properties and stability of the soil. However, challenges such as achieving uniform resin distribution and accurately estimating injection volume and pressure exist. Ongoing research focuses on optimizing injection parameters, studying long-term performance, and understanding resin-soil interactions. Overall, soil injection using polyurethane resin shows promise for ground improvement and foundation stabilization, and further research is necessary to refine the technique and establish design guidelines for different soil conditions. This article provides an overview of the technology, including its properties, applications, advantages, and limitations, and presents a case study to demonstrate its effectiveness. The information presented enables engineers and construction professionals to make informed decisions about implementing this innovative technique in their projects.
