Post Tensioned GFRC For Longer Concrete Countertop Spans

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.
