A high quality surface preparation of concrete structure is the condition for successful concrete surface repair. One of the modern methods of removal of degraded concrete layers and obtaining desired parameters of the concrete is using of high speed water jets technology. Regulations in ecology (dust, noise, vibrations, deposits) and in concrete repair quality (crack absence, surface structure, reinforcement), but also economical aspects have supported the introduction of water jet tools in the area of concrete repair. The paper deals with concrete surface layers removal by high speed water jet technology. The paper recapitulates knowledge from research of the effect of the corrosion of concrete on the result of interaction between the high-speed water jets technology and the concrete - according to quality of concrete, strength characteristics, type of corrosion. Concrete surface layers of various qualities were removed by continuous and pulsating water jets, continuous rotating jets and pulsating rotating jets. Generation of high-frequency pulsations in high speed water jets enables to increase the cutting performance of water jets.
