An experimental programme for the optimisation of concrete structural and non-structural repair was performed. The programme focused on the development of sustainable durable repairs throughout the enhancement of substrate-repair bond and compatibility, as well as the development of efficient solutions for crack control. As part of the programme, mode-I fracture characterisation of a substrate-repair interface was addressed. The repair material was a mortar reinforced with polyvinyl alcohol (PVA) fibres. Experimental tests, crack growth resistance analysis and major results are presented and discussed in this paper. Mode-I crack growth resistance tests were performed by means of the contoured double cantilever beam (CDCB) test. Tensile fracture analysis was supported by splitting (indirect) tension tests.
