Existing concrete surfaces need to be roughened to a profile necessary to achieve mechanical interlock with repair material. Surface mechanical morphometry is based on the measurement of surface profile - profilometry - which can be extended to 3D representation with surfometry by means of a stylus registering the profile. Profilometry and surfometry analysis were realized on concrete after different surface treatments (grinding, sandblasting, shotblasting, hand- and mechanical milling). The profile has been quantified by means of statistical and amplitude parameters calculated from the waviness (lower frequencies) and the roughness (higher frequencies) profiles of the surface. Bearing ratio and Abbott's curve observations are also very useful to characterise surface profiles.
