This dissertation deals with problems solving of qualities prefabricated elements from concrete (lock paving on constructions.) Experience says to us, that the quality of lock pavings on constructions is considerably various, even if construction were realized in the same period. The samples of lock paving were chosen from seven already realized constructions for comparison qualities.These construction were realized in same and different years. For comparison, it was effected measuring of pavings directly at point of realization via aspect and enumerate of inequality, defects and sufferer pieces of paving. Further, for laboratory evaluation, they were taken away samples from each construction and they were effected tests according to valid standards destined for concrete paving blocks ČSN EN 1338 from December 2004 – Concrete paving blocks and test method. There is technical process during taking - over supplies of lock paving, sub - operation at realization and of all built structure this way modified surfaces according to valid legislature on the end of my dissertation
