What is Modified-GFRC?

Glass fiber reinforced concrete (GFRC) has a long history of use in building facades, and was originally developed for its superior performance in seismic zones. The decorative concrete industry embraced it not only for its strength, but the versatility it provides for creating texture, color and form otherwise impossible with traditional precast.

The basic principles of GFRC are simple. Typical mix designs use a cement rich blend, combining one part cement to one part graded, dry sand. With the addition of water, curing polymer and glass fiber for reinforcement, GFRC is typically cast at 0.75” to 1“ thick. Mixes can be modified for sprayed applications or plasticized with water reducer to create self-consolidating concrete.
