Currently, the use of mat foundations in small buildings has intensified, however, this alternative cannot be used in soils with low load capacity. An alternative is to promote an improvement or reinforcement of the base layer. For this purpose, this work is an evaluation of the mechanical behavior of a fine sandy soil reinforced with terephthalate (PET) fibers for use as a mat foundations base. Reinforcement models performed in the field with layers of 300 mm thick compacted soil were used in the optimal conditions of compaction reinforced with 1% PET fibers. Performance evaluation was performed using static load tests on a 340 mm diameter circular plate. Tests were carried out in three conditions: soil reinforced with fiber, soil compacted without reinforcement and natural soil. The results showed that the addition of fiber improves the load capacity, increases the rigidity, decreasing the displacements for the service loads, and the rupture surface mobilizes a larger region. It is concluded that the addition of fiber improves the performance of the base layer, presenting a gain in load capacity, however, this gain occurs for large displacements.
