The need for construction of new buildings is currently still growing. For construction are also used areas that were previously labelled as unsuitable or less suitable in terms of subsoil. The design, construction and implementation of building foundation, including subsoil modifications (foundation base) has a decisive influence on the building lifespan and its safety. This article presents an application of risk analysis method Umra (Universal Risk matrix analysis) to classify different types of subsoil. The method is applied to determine the degree of the soil suitability, which consists of different types of materials (waste from mining, compacted embankment, landscaped subsoil, unmade ground) for foundation engineering. Treated as well as untreated subsoil can cause various faults and damage to an object built on it. Users, however, perceive the level of risk of the occurrence of this damage differently. Also, every user of a building perceives differently the danger associated with founding an object. What plays an important role here is knowledge of the possibilities of construction and the suitability of each type of subsoil for construction of buildings.
