The fiberglass mesh provides reinforcement through tensile and flexural strength, holding together the other ingredients, including concrete, aggregates, water, additives and polymers. The amount of fiberglass mesh in a mix depends on the requirements of the construction project for which it is being used.

The fiberglass mesh works as a central part of the GFRC manufacturing process, which is usually developed by using one of two methods. The hand lay-up method introduces the fiberglass mesh as a mat that is layered with the other materials through a manual process. The chopped-strand-spray method introduces the fiberglass mesh into the concrete mix as it is being sprayed into the custom mold. Either manufacturing process uses the fiberglass mesh to create   high-quality, custom products.
