The paper discusses the application of the L-type Schmidt rebound hammer for determination of the uniaxial compressive strength of discontinuity surfaces of rock masses. The result revealed that there is no correlation between L-type rebound hammer values and uniaxial compressive strength, if it is applied on natural rough joint surfaces under saturated conditions.
