Pathological analysis of adobe (banco) constructed habitats in the city of N'Djamena in Chad shows that the most frequent defects observed are, among others, the abundant appearance of cracks, the erosion of external walls, water infiltration and subsidence. At different stages of identification for the choice of material (earth), brick production and its implementation, this work proposes simple and practical solutions to avoid the above mentioned defects resulting from traditional techniques. Thus, geotechnical tests are proposed to identify the right soil, rice bales must replace the straw for earth treatment and finally a foundation system (insulated sole - primer post - underbody wall - sill) of reinforced concrete must be constructed to ensure the stability of the structure.
Author Keywords: adobe, brick, habitats, fissure, erosion, subsidence, treatment.

Pathological analysis of adobe (banco) constructed habitats in the city of N'Djamena in Chad shows that the most frequent defects observed are, among others, the abundant appearance of cracks, the erosion of external walls, water infiltration and subsidence.

Abstract: (french)
L’analyse pathologique d’habitats construits en adobe (banco) recensés dans la ville de N’Djamena au Tchad montre que les défauts les plus fréquents observés sont entre autres, l’apparition abondante des fissures, l’érosion des parois externes, l’infiltration d’eau et l’affaissement. A différentes phases de l’identification pour le choix du matériau (terre), de la production des briques et de sa mise en œuvre, le présent travail propose des solutions simples et pratiques pour éviter les défauts précités issus des techniques traditionnelles. Ainsi, les essais géotechniques sont proposés pour identifier le bon sol, les balles de riz doivent remplacer la paille pour le traitement de la terre et enfin, un système de fondation (semelle isolée - poteau d’amorce - mur de soubassement - longrine) en béton armé doit être réalisé pour assurer la stabilité de l’ouvrage.
Author Keywords: adobe, brique, habitat, fissure, érosion, affaissement, traitement.
