Analysis of tests on soils with randomly distributed fibre reinforcement an possibilities of its application in geotechnical and environmental engineering were presented in the paper. Using this type of reinforcement make it is possible to form flexible earth structures with green surfaces and relatively high resistance on different settlement substituting heavy, rigid and strange in the landscape concrete structures. By mixing synthetic fibers, both specially produced as reinforcement or other ones eg. recovered from waste carpets or foils, with soil and sometimes very small amount of cement, shear strength resistance and its residual value increase is achieved. Reinforcement dose not disturb growth of plants or water infiltration, so the fiber-soil composite is an environmental friendly solution. Higher strength is positively influencing other soil parameters like piping resistance or resistance against erosion, but in this field of application there is much less investigation data. ...
Superabsorbents (SAP) are loosely crosslinked hydrophilic polymers can absorb a large amounth of water. In a soil it works as moistre bufor limiting plant water stres. It has been observed mixing SAP with soil decrease its strength parameters. To prevent that phenomena a kind of geocomposite absorbing water was introduced. It is a flat tube made from geotextile, filled with superabsorbent. Application of the geocomposite limits a problem of water avability for plant, which increase slopes erosion resistance. ...
Factors determining water erosion of slopes and standard anti erosion methods were presented. The analyze of erosion control methods applied in North America induced authors to present methods of soil intercepting in favorable sites on the slope. Methods of erosion limiting in a small watershed based on temporary and permanent barriers, sedimentation basins, ponds and small reservoirs were described. Construction of temporary barriers, basins with permeable divisions, ponds and reservoirs with tower and emergency outlet were presented. ...
