The paper focuses on a computer nonlinear analysis of the formation and development of cracks in a concrete slab exposed to a uniform continuous load on the lower surface. The analysis is based on an actual example of the formation and development of cracks of the width of approx. 0.3 mm in a basement slab exposed to ground water buoyancy. The paper illustrates the setting of the material model of the reinforced concrete slab according to the actual material properties and the similarity of the computer results to an incident of real damage to the basement structure. On the basis of the same cracks on the model and on the real structure, a load value that caused this damage was estimated. The aim of this article was to find such material characteristics of a basement structure of the same size and shape and under the same extreme load that shows cracks with a maximum width of 0.1 mm to ensure the waterproofing safety.
