This paper presents results of laboratory assessment of creating seepage barriers in a sandy soil using biopolymer additives (bio substance), which consist of polysaccharides and water. Polysaccharides strongly interact with water to produce a viscous suspension. The aim of the conducted work was to investigate the influence of a biosubstance employed in a highly permeable sandy soil. The amount of the biopolymer used in a sample fell between 0.1 and 1.5%, by dry weight. Tests were carried out on two different specimens, coarse sand (1.18 - 2.00 mm) and medium sand (0.075 - 1.00 mm). The test results indicate that the hydraulic conductivity values change significantly based on the amount of bio substance, gradation of the sand and curing time. It is concluded that such application, which is a relatively new soil improvement technique, could be used as a seepage barrier installation, required to protect some geotechnical works including foundation, underground structures and waste disposals.
