This work is focused on the groundwater flow and transport of contaminants in the environment of granitic rocks. Mainly adjective and dispersive types of transport of contaminants are discussed in this work. Transport of contaminants by diffusion is mentioned only marginally in relation to porosity of rock matrix. The main aim of this work was to characterize hydraulic and mechanical-physical parameters of the granite. Partial objectives were to verify the sealing function of the laboratory grout mixture in fractured granite blocks, to characterize the porosity and hydraulic conductivity of the granite matrix at laboratory scale, to find connection between boreholes in situ and to establish a link between the structure of rocks and velocities of seismic waves. Four bentonite and cement mixtures in different weight ratios have been selected as a grout mixture. Suitable injection mixture was selected based on the results of hydraulic conductivity coefficient, and other aspects, such as volumetric stability. The granite blocks were partially grouted by using of the selected grout mixture. Hydraulic conductivity and porosity of the granite rock matrix from the Panské Dubenky test site was tested at three laboratory samples. Hydraulic conductivity was determined with different constant hydraulic...
