The study focuses on the physical characterization of soils in the city of Oum-hadjer and classification. The field work showed that the soils of the study area are heterogeneous (fine sand little silty to silty) in most sites. This heterogeneity is related to the geological context of their formation. The results obtained show that the soils of the southern part of the city of Oum-hadjer have a low percentage (22.6%) in fine particles whose dimensions are less than 0.08 mm. According to the GTR 92 classification, these are gravelly soils that belong to class B5 (80µm sieve between 12 and 35%, 2mm sieve ≤ 70% and Ip < 12). The plasticity index varies from 3.6% to 6.5% with an average of 4.7% gives the studied soil a non-plastic character. The use of these soils as foundation of ordinary buildings in the southern part of the city of Oum-hadjer would not present any risk if the footings are laid at 1.5 see 2m depth. As for the northern part of the city of Oum-hadjer, the materials are clayey and their use as foundation requires special attention for a good holding and durability of works.
