At the moment, many of the parking garages around the world are constructed with steel reinforcement bars and concrete. The problem with using concrete and steel is that road salt trekked in by the cars is corrosive and causes the concrete crack. Once the concrete cracks and the steel reinforcement is exposed to the salt, the steel immediately begins to corrode.

Using MST-BAR as primary reinforced concrete in parking garage slab actually cost less than an equivalent steel solution. After concrete is cast over steel rebar, a waterproofing membrane and a 65 mm thick layer of asphalt that are typically placed over steel-reinforced concrete to protect the concrete and steel from moisture ingress weren’t needed. The lack of asphalt and the low-weight of the GFRP rebar reduced slab weight.
