With the increase in population, there is a dearth of land suitable for infrastructure development. Due to poor engineering properties, many areas of land remain unutilized which also slows down rapid development. Areas containing peat soil are among the most unutilized land in many regions of the world. Total area covered by peat soil is 4.23 million km2 (Xu et al. in Catena 160:134–140, 2018 [1]). Peat deposits have been discovered to be widespread throughout the world, taking up between 5 and 8% of the planet's geographical area (Mesri and Ajlouni in J Geotechn Geoenviron Eng 133:850–866, 2007 [2]). Peat soils are formed from partially decomposed plant material under anaerobic water saturated conditions. They are categorised based on their level of humification. These peat soils are characterised by high moisture content, low bearing capacity, high porosity, and high compressibility. Different stabilisers used for peat soil stabilization can be broadly categorised into cementitious material (Portland cement, fly-ash C, slag cement etc.), geopolymer and other non-conventional material (envirotac, effective microorganism etc.). Different studies have demonstrated that the unconfined compressive test performed on every type of peat sample with varying quantity of each stabiliser shows a significant increase in the compressive strength. The optimum strength of each stabiliser obtained in different research have been compared in this study. Results of Permeability and UU triaxial tests are also studied by some researchers. It is also found that various places have different peat soil depending on their humification level and environmental condition, thus suitable stabiliser for that place can be found after extensive research with an emphasis on locally available materials. In this article, results of several studies conducted on peat soil are reviewed to understand the improvement of engineering properties of peat soil after stabilization. Each stabilizer is studied thoroughly to understand its feasibility in peat soil stabilization and impact on environment.
