    The paper deals with laboratory research of geocomposites which are produced by propagating and subsequent of chemical grouts hardening in porous space of cohesionless soils. Chemical grouting of cohesionless soils are performed in order to improve strength and deformational properties of grouted soils and in order to reduce mainly their water permeability. This paper discusses the influence of the permeability of cohesionless soils by means of chemical grouts. The permeability of geocomposites is evaluated by means of laboratory defined hydraulic conductivity. The hydraulic conductivity coefficient of geocomposites is an important parameter for the evaluation of sealing chemical grouting. To address the problem cylindrical geocomposite specimens are prepared by drilling in order to perform permeability measurements. The concept of specimen preparing as well as methods for hydraulic conductivity measurements at orthogonal geocomposite specimens are discussed too.
