In this episode of the Concrete Logic Podcast, Forta Corp’s TJ Lambert makes the case that your reinforcement choice may be one of the biggest — and most overlooked — schedule killers on the job. He breaks down how traditional rebar creates hidden bottlenecks at every stage, from procurement to pour day, and how fiber reinforcement removes many of those constraints by putting the reinforcement inside the mix itself.
The conversation spans fiber types, finishing challenges, sustainability metrics (EPDs, 20–60% GWP reduction vs. rebar), and the ACI code pathways engineers need before specifying fibers. TJ’s takeaway: don’t just swap rebar for a dosage — work with your supplier to build a ground-up design that’s optimized for your actual project.
Every project has a different constraint — schedule, carbon targets, finishing crew experience, engineer sign-off. The four topics TJ covers in this episode map directly to those pressure points. Dig into whichever one is most relevant to your work right now.
One of concrete’s hidden inefficiencies is the gap between what’s engineered and what gets built. Calculations call for #4s at 15.5″ — the field rounds up to 12″. Fiber closes that gap. Dosage can be tuned precisely to actual performance requirements, and without bar on the slab, pour sizes can grow from 30,000 sq ft per day to 40,000 or more.
Tying bar, lifting mesh, managing pump placement — every one of those steps can stall a pour. Fiber removes them. With reinforcement in the drum, crews can direct-discharge, run multiple trucks simultaneously, and work unobstructed. On the plant side, dissolvable bags and a straightforward loading process add as little as 1–2 minutes per load.
Every Forta product carries a published EPD and Life Cycle Analysis. Project-specific carbon reduction calculations typically show a 20–60% reduction in embodied carbon vs. traditional rebar — with the largest gains when replacing heavier steel configurations with macro synthetic fiber. Domestic manufacturing in Michigan and Pennsylvania also supports Buy America compliance on federal projects.
Fiber has well-established code support — ACI 544, 360, 330, and 318 Chapter 1.10 for structural applications — but knowing which pathway fits your project takes expertise. Forta’s team conducts full mix design reviews and provides calculations that engineers can put their name on. The approach: build from the ground up based on actual loads, subgrade, and code requirements — not a dosage chart.
