From the outset of the project, Form & Build Supply worked with the concrete contractor and engineering firm to try to replace some rebar with Forta-Ferro reinforcing concrete fibers. These patented fibers are an incredibly tough and durable three dimensional concrete reinforcement solution; an ideal substitute for rebar on horizontal applications. These fibers have been proven to reduce plastic and hardened concrete shrinkage, improve impact strength, and increase fatigue resistance and concrete toughness.

With that in mind, the fibers were originally intended for use on the project’s mezzanine floor where limited access made getting rebar to its intended spot very difficult. Unfortunately, the Engineer was not able to approve the fibers for this application in time.

However, as construction progressed and steel prices continued to rise, the concrete contractor looked more seriously at using Forta-Ferro for the 400 m3 slab-on-grade they needed to pour. For this application, the contractor worked with Form & Build to have the fibers approved with ample lead time. The use of the fibers benefited the contractor in two major ways. First, with record high steel prices, they saved money on a direct material-to-material basis.
Second, removing the rebar saved an estimated two days in labour costs otherwise required to place and tie the rebar. As a bonus, the contractor was also very impressed with the high quality finish they achieved with the fibers.

Construction comes with no shortage of challenges and changing circumstances. At Form & Build Supply we’re proud to be here to provide solutions that help you get the job done right. Interested in learning more? Email Derek Liddle here
