The Use of Geogrids in the Reinforcement of Weak Foundation Soils: A Remedial Strategy for Improving Ground Stability

Abstract: This paper presents a value-added approach to improving ground stability and mitigating foundation failures using geogrids as a reinforcement material in weak foundation soils. The primary focus of this research was to evaluate geogrids as an effective and sustainable solution for enhancing the load-bearing capacity and structural reliability of foundations constructed on weak or problematic soils. The reinforcement system using geogrids was designed to increase the shear strength of soil and reduce settlement by integrating geosynthetic materials within the soil mass. This paper aims to develop a comprehensive understanding of the behavior of geogrid-reinforced soil systems with the sole goal of promoting their application, both in new construction and foundation remediation projects. This research began by reviewing various remediation systems or strategies used in combating foundation failure, that is, their effectiveness, efficiency, and limitations. It further discussed the use of geosynthetics, particularly geogrids, as a remedy for foundation reinforcement. Characteristics, mechanical properties, efficiency, and their wide range of applications was critically analyzed to gauge their suitability as a reinforcement material. Furthermore, the research focused on identifying the limitations and practical deployment challenges of geogrid-reinforced foundations. To achieve this, the study analysed experimental evaluations to assess the degree of improvement achieved by geogrid reinforcement. This study ultimately provides an assessment of the feasibility, efficiency and potential for geogrids as a remedial method for addressing foundation failures in weak soils.
