The contribution is focused on assessing of important physical and mechanical properties of rocks quarried in Brezovské Karpaty Mts. with the aim of their utilization as decorative and prospective building stone for restorations. Carbonate sandstones and conglomerates of Upper Cretaceous and carbonate sandstone of Neogene sedimentary strata in Chtelnica - Trianova and Chtelnica - Malé Skalky were taken into consideration. Those quarries appeared to be suitable for excavation of an appropriate material for statuary and monumental purposes and for restoration work, as well. Samples for assessment of rock properties were taken from abandoned and quarry in operation. Tested specimens for laboratory tests in a form of cubes and cylinders were prepared from monoliths and drilled cores taken from the depth up to 1 m. For determination of rock quality following tests were taken as most relevant: densities, porosity, water absorption and strength properties estimated according to valid technical standards. Based on physical and mechanical properties of rocks assessed on a number of tested samples from two mining sites in Slovakia and one comparable site in Austria, quality assurance of the rock utilization as a decoration/restoration material is presented.
