Over the last century, ground improvement techniques, which are rising rapidly as worldwide development for the utilization of unstable or soft soils, have been developed and nowadays many of them are widely used in geotechnical engineering projects. Considerable developments have occurred since the twentieth century. Ground improvement techniques continue to make considerable progress, both quantitatively and qualitatively, as a result of not only technology developments but also of an increasing awareness of the environmental and economic advantages of modern soil improvement methods. Various ground improvement techniques can be characterized as the modification of existing soils or earth structures to provide better performance under design and/or operational conditions. The main goal of most soil treatment methods whose basic principles has been not changed since the past of mankind is to improve the soil characteristics. The ground improvement techniques utilize either mechanical energy or man-made materials. Guar gum is formed from cymposis tetragonoloba and Xanthan gum is formed by xanthomonus campestris during the process of fermentation. For the sample preparation, two different mixing methods can be adopted: dry mixing in which the biopolymer was directly mixed with the soil before adding water and wet mixing in which biopolymer was mixed with water to form hydrosolution before mixing in the soil. Dry mixing method was used. Soil sample mixed with various percentage of biopolymer (0.6%, 1.2 %, 1.8 % and 2.4 %).
