Abstract

Recent surge in the urbanization has led to a massive growth of infrastructure around the world. This has led to construction in soil mass considered otherwise unsuitable for construction. Ground improvement is an essential condition to build any civil engineering structure in these type of soil as they are found to have low bearing capacity and uneven settlement among other drawbacks. Geosynthetics are being widely used for the last two decades as soil reinforcement to improve the quality of soil owing to their ease of operation and overall cost. Geocell is the most advanced form of geosynthetics. Geocell is a three dimensional, polymeric, honeycomb like structure of cells interconnected at joints. The soil particles can be trapped inside these cells providing an overall confinement to the soil layer and improves it properties regarding support of civil engineering structures. Several researchers have shown the efficiency of geocell in improvement of bearing capacity of foundation when the soil is reinforced with geocell. The present paper is a review of the experimental techniques adopted to assess the performance of geocell as a foundation reinforcement material and validates its use for further by the practicing engineers as a soil improvement medium.
