Abstract The growing need to develop infrastructure, driven by global population explosion is forcing construction on all types of soils, including weak/marginal soils. However, due to the poor physical and engineering properties of weak soils, they are not suitable for construction purposes and hence require improvement. Many geosynthetic ground reinforcement techniques are presently employed to improve the properties of weak soils and to reduce the potential damages caused by them, including immediate settlements and slope failures. Use of geocells and the methods of improving the properties of weak soils, especially those applied in pavement and foundation engineering, have been studied over the last several decades. This article seeks to present a review of laboratory experiments, field-scale studies and analytical studies of geocell-reinforced structures that would be beneficial for multiple applications and further research studies. The review concluded that geocell has the potential to improve weak soil types for engineering applications. Keywords Weak soil Soil reinforcement Geosynthetics Geocell I. R. Sheikh (&) M. Y.

1 Introduction Rapid urbanization has increased the demand to construct structures over weak/marginal soils, which in turn puts a lot of pressure on engineers to improve soils. Many researchers have tried utilizing waste materials for soil stabilization and environmental friendly biological processes but due to their restricted in situ applications such innovative techniques still need to addressed for practical field applications and overall cost reduction (Wani and Mir 2020a, b, c, d). Numerous ground stabilization techniques that are commonly used include mechanical stabilization, chemical stabilization and soil reinforcement etc. but due to their high cost and environmental effects these techniques tend to find limited use now a days as the society is growing in concern over sustainable products and materials. Amongst available soil reinforcement techniques using geosynthetics is considered to be a sustainable and cost effective solution. The application of geosynthetics in the field of pavement engineering and building constructions has found numerous benefits in terms of reduction in settlements, increase in bearing capacity etc. The geosynthetic inclusion offers ease in construction and lower construction costs by minimizing the use of construction material. Geocell, a type of geosynthetic is a threedimensional honeycombed cellular arrangement that offers confinement to compacted infill material. The geocell restrict the lateral spreading o
