WHAT IS GRC?
If you are architecturally remodeling your home and have heard the term GRC tossed around, you may be wondering what exactly it is. Well, GRC is an acronym for Glass Fiber Reinforced Concrete. It is a composite material that consist of portland cement, fine aggregate, water, additives, color pigments and most importantly—GLASS. This popular glass reinforced material can be used to replace standard concrete in architectural designs, facades and elements. Even some engineering projects utilize GRC in its designs because of the material’s many benefits.
The main advantage of GRC over standard concrete is the composite’s lightweight attributes. On average, GRC is 10X lighter than concrete. Because of the significant weight difference, the glass reinforced material is more economical, easier and faster to install. It also allows the composite to be cast in unlimited shapes and designs—including 3D designs. But this lightweight substitute for heavy concrete is not slight in the durable department. GRC has proven to be extremely durable and resilient. It can stand up to weather elements like heavy rain, wind, scorching sun and salt-water environments. As for winter, it is even more freeze thaw resistant than standard concrete so it won’t shrink as much as regular concrete.
Other advantages of GRC include that it looks completely natural– just like real carved stone or limestone (without the weight of course) and its flexible strength. Because of the mixture’s moldable nature, it can be cast into beautiful architectural designs that will last a very long time. Artisan designers appreciate the creative freedom the material affords them. And because GRC is cast / precast, it allows for fine artistic details to be sculpted into architectural elements such as fireplace mantels, kitchen hoods or any other custom architectural project. Common exterior architectural accents that benefit from utilizing GRC are columns, copings, balustrades, wall caps and pavers.
