Understanding Glass Fiber Reinforced Concrete (GFRC) for Countertops

Posted on 18 May 2015 by cradmin

This video is really a sort of online seminar presented by the Concrete Countertop Institute(CCI), designed t0 teach how polymer really works, what fibers actually do and the meaning and importance of flexural strength in glass fiber reinforced concrete (GFRC) countertops. The video is basically a PowerPoint Presentation, narrated by CCI founder Jeff Gerard, which covers quite a bit of information.

Of course it is a bit self-promotional at the end where it discusses training programs offered by the CCI, but overall there is a lot of interesting and useful information for those working in the concrete countertop segment of the industry.

You might also be interested in this Trinic video on post tensioned GFRC for longer concrete countertop spans by Mark Celebuski.

Post Tensioned GFRC For Longer Concrete Countertop Spans

Posted on 22 August 2014 by cradmin

Once again, Mark Celebuski of Trinic, has developed another useful video covering how to avoid sagging with long spans of glass fiber reinforced concrete (GFRC) countertops. The video demonstrates the possibilities of post tensioning using the company’s GFRC Admix, but the theory behind it could certainly work with other admixes with similar properties. Basically, it is done just using some rods purchased at a hardware store. According to the video, very large loads, long spans and extreme cantilevers with GFRC are all possible using these simple tools and techniques.

Here are a couple of other concrete videos put forth by Celebuski and Trinic that we have featured in the past that you may also find of interest.

Fundamentals of GFRC

Posted on 11 July 2014 by cradmin

This video, produced by ModaCrete and Mike Cook (a well known member of the concrete countertop industry), covers the “Fundamentals of GFRC” and was put together so that individuals can get an idea of the complexities of producing high performance concrete countertops with GFRC technologies. It is not all encompassing but will deliver the basics. Cook said the next step is “developing the necessary, physical skill sets required to be successful with GFRC.” And for that, he suggests hands-on training.

There are some good insights here for those exploring GFRC and the world of concrete countertops – give it a look. Or check out these other videos related to concrete countertops.

And, as always, let us know if you have other videos you think we should share on the subject, or any countertop-related subject.

Concrete Countertop Solutions Fiber Mesh ReinforcementConcrete Countertop Solutions offers the new Z Liqui-Crete System that combines a fiber-fortified concrete mixture with a 1- by 1-in. fiberglass mesh grid. The system uses an easily attached Z-clip to hold the mesh at the proper height during the pour. The clips, which arescrewed down to the cement board substrate and clipped onto the mesh, work with the company’s 1-5/8-in. Z Counterforms and hold the mesh a third of the way below the surface. A longer clip is also available for taller commercial forms. According to the company, the system allows for the addition of enough water to achieve a consistency that allows it to be poured right through the mesh grid, without sacrificing the strength of the material.

A series of videos produced and released by Trinic LLC sheds light on some of the mystery surrounding the fabrication of concrete and GFRC countertops. Trinic is a respected concrete specialty company in Windsor, N.Y., co-owned by Bob Chatterton and Mark Celebuski.

Celebuski holds free concrete training sessions for Trinic’s customers. The sessions are videotaped as they are conducted and uploaded to the company’s YouTube page where they can be accessed by anyone interested. Celebuski states that his goal in holding his classes and producing his videos is “to make the physical process as pain free and easy as possible and let artists be artists.”

The following video is part one of the Concrete Countertop Class Lecture, and it provides an overview on the process of mixing concrete for countertop fabrication. Other videos in the series are on wet casting, GFRC, fiber optics, fabric forming and sealers.

Tips for Spraying GFRC Face Coat on Concrete Countertops

Posted on 29 January 2013 by cradmin

Here is a video we came across with some good tips for spraying a glass-fiber reinforced concrete face coat on concrete countertops. Unfortunately the author, “nvconcretedesignnsd,” doesn’t give us much information about himself, but he does offer some good insight into the process. Those working with GFRC in countertop applications may want to give this one a look:

Great Informational Outlet for Concrete Countertops

Posted on 19 August 2012 by cradmin

We ran across a great resource for those thinking of installing concrete countertops, or just want to know more about the options, at ConcreteNetwork.com . They have a series of highly informative articles about concrete countertops. This informational website has something for everyone interested in concrete counters, whether you are a fabricator, designer or customer. The articles cover details ranging from how concrete countertops are made and installed  to what the finished product looks like and how to clean them.

As the world in general becomes more eco-friendly, the world of concrete countertops is no exception. There is a series of articles on how concrete countertops can be made “green.”  These articles can help ensure that concrete countertops encourage sustainability and are manufactured in an eco-friendly manner.

When considering all countertops’ needs, there many options available. Reviewing all of these options might be a little overwhelming, but the site has fashioned a very handy comparison chart showing different pros and cons of six common types of countertops. They compare staining, grout lines, sealing, appearance over age and other topics. There is also a comparison of the average price per square foot, making getting down to the “bottom line” easy to accomplish.

Are you or your client interested in a higher degree of personalization? Then check out the  section that has some wonderful information on the wide variety of designs that can be woven into  concrete countertops. While the word concrete may conjure up images of Cold War era Poland, this material is quite versatile and can be made to look incredible. One option is to embed glass in a concrete countertop. In this option, individuals have the ability to personalize the countertop to their own decorating tastes to a very high degree. While the process takes time (28 days before it is dry from the sealing process according to the article), the time spent may be more than worth the effort and wait if it is something that is really desired. Another article details how to personalize a countertop with item such as shotgun shells, spoons or even car gauges. A creative mind can surely find other unique methods of personalizing a countertop, and use these ideas as a springboard.

Also included are three articles on how these countertops are manufactured. Here, a person can learn the difference between cast on site or in the shop , size limitations/seams in countertops, and how thick and heavy a concrete countertop will be.

The countertop selection process can be made easier by these informative and descriptive articles. No matter which countertop is selected to beautify a new home (or add spice to an old one), this site is worth checking out as a resource in making a smart decision, or just getting informed.
