GFRC is an extremely versatile material which Architects, Designers, and Engineers   worldwide are utilizing to create the most ambitious designs. It can be molded to form   modern futuristic shapes, or to create classical architectural features. With an almost   unlimited range of shapes, colors, and textures, designers have unrivaled freedom to push   the boundaries of modern construction using this innovative material.

Material Specifications


CGA Stoneworks manufactures GFRC (Glass Fiber Reinforced Concrete), Architectural Cast Stone , and Architectural Precast materials, each with its’ own unique capabilities to meet the requirements of your construction projects. Below you will find CGA Stoneworks standard specifications, quality control program, and general information regarding GFRC material and it’s benefits.


03491  Glass Fiber Reinforced Concrete


This section covers glass fiber reinforced concrete (GFRC) as manufactured by CGA Stoneworks LLC. GFRC is a lightweight concrete product manufactured with alkali resistant glass fibers at a nominal thickness. Generally used for exterior facades and architectural ornamentation on both new construction, and restorations. It can be produced in virtually any shape, color, or texture. GFRC is a strong, durable, sustainable, flexible, and versatile material. CGA manufacturers GFRC products by the spray-up, and premix methods depending on the specific application and project conditions. Consult CGA Stoneworks for assistance in editing this section for your specific project application.

Glass Fiber Reinforced Concrete – Quality Control Program

CGA’s glass fiber reinforced concrete is held to a strict set of standards, which maintainsthe guidelines of the Precast/Prestressed Concrete Institute’s Recommended Practice for Glass Fiber Reinforced Concrete MNL-128-01. To insure our products always meet our commitment to producing the highest quality GFRC available, we have a stringent Quality Control Program that is second to none. Every piece produced has gone through a rigorous inspection in each department of manufacturing and signed off by the Production Manager prior to moving into the next stage of manufacturing.

Below is our standard Quality Control Program outline, which can be edited to meet your job specific criteria.

GFRC – LEED Rating System

The LEED rating system is the most widely used tool in assessing the environmental impact of a building and its components in the United States. As Architects work towards designing “greener” buildings, the LEED system provides a means of analyzing how eco-friendly their design is by awarding points in five environmental categories which leads to an LEED Certification. The use of our GFRC Architectural products can make a significant contribution toward earning LEED points on a project. These include ID2.1 Durability and Planning Credit, ID2.4 Third Party Durability Inspection, MR 4.1 & 4.2 Recycled Content, ID 2.2 Indoor Moisture Control, and MR 5.1 and 5.2 Regional Materials.


GFRC = Minimal Environmental Impact

Glass fiber reinforced concrete is an environmentally friendly product. The main ingredients of GFRC are based on naturally occurring earth oxides that are used in the manufacture of glass fiber and cement. An assessment carried out in the UK as part of a DETR and Concrete Industry Alliance ‘Partners in Technology’ project compared two concrete and GFRC products that fulfill the same function. The results show that GFRC has a much lower environmental impact of 60%.
