Abstract—This paper discusses problems associated with masonry rehabilitation techniques, as well as the use of composite materials in sewage-system infrastructure. The goal of the experimental design presented in this paper is to study the effect of Fibre Reinforced Mortar lining, which was strengthened with composite materials of modest thickness, during the restructuring of ovoid masonry works. To this end, failure tests on reinforced and non-reinforced masonry vaults were conducted. The implementation of a mortar lining reinforced with composite materials (i.e., carbon-fibre strips and fabric) increased the tensile strength and delayed the onset of cracks. The primary advantage of this type of lining in comparison with conventional reinforcement, such as reinforced shotcrete lining, includes considerable gains in rehabilitation durability and the preservation of the structure’s hydraulic capacity.
