This paper presents the results of laboratory and field tests on the hydraulic properties of georopes produced using the Kemafil technology from sheep wool waste generated in the textile industry. The laboratory tests included the determination of the basic physical parameters and filtration properties of georopes, as well as tests of the physical properties and water permeability of the experimental training ground. As part of the field research, measurements of water infiltration through 1.0, 2.0 and 5.0 m long georopes embedded in the ground were carried out in nine monthly cycles. The conditions of water flow through the georopes were monitored on the basis of georope resistance measurements. Numerical calculations were also performed to determine the conditions of water flow through the georopes and the process of water infiltration from the georopes into the ground. The laboratory tests have shown that the water permeability of georopes is high and, based on the filtration criteria, they can act as a drainage material. The field measurements showed that the resistance of the georopes changed over time and depended on the amount of water supplied and the absorbency of the ground. The results of the numerical calculations were consistent with the results of the field measurements, at the same time indicating that some water infiltrated into the ground in the vicinity of the georopes, meaning that under the conditions that prevailed during the experiment, the georopes can act as infiltration drainage systems in the ground.
