This topic was debated a while back on this list. Since then, I contacted the corporate offices of a major polypropylene manufacturer. I told them of the debate here and internally within our company. I asked them point blank if it was appropriate to replace reinforcing steel with polypropylene fibers. They also inferred on their web page that they performed engineering services. I also asked if they would seal the design on a slab on grade. I never received an answer. I will not use fibers in lieu of mesh or rebar. There are appropriate uses for fibers (examples: in addition to steel to control plastic shrinkage cracking, or in stair pans). I've seen projects where polypropylene fibers were used in lieu of steel mesh or rebar for a slab on grade, and I have seen an engineering firm shell out thousands of dollars to settle the case. The slab had to be replaced.
