The repair of parking garages using composite rebar instead of steel in the reinforced concrete slabs is a better design option, according to this article. Among the benefits of the composite rebar is a prolonged life for the building, says Brahim Benmokrane, research chair of the Natural Sciences and Engineering Research Council of Canada. "Reinforcing concrete with FRP bars would extend the life of a structure to 100 years or more, compared to steel-reinforced concrete, which needs major restoration after 25 years," Benmokrane said.
