Information on polymer fluids for supporting pile boreholes and diaphragm excavations, properties of natural and artificial polymers, way of its performance, differences against bentonite slurries are presented. Rules of using of polymer fluids, their production, concentration of polymers, checking of their properties, regeneration, disposal and mistakes made sometimes are described. The advantages of the polymer fluids are easier production than of the bentonite slurry, smaller equipment and storage tanks, quicker making ready to use, and also clean working site, ease cleaning of a section before concreting and easier disposal of used up liquid. However, it is necessary to check a full removing of the sand sediment and cleaning up of the bottom of a borehole or excavation before concreting. Examples of polymer fluids application in Poland are given.
