Bob Higgins warns that focusing only on compressive strength misses the real durability killers hiding at the concrete’s surface in real-world conditions.
Bob Higgins explains how cooler curing slows early strength but leads to far stronger concrete by 365 days—changing how we should judge mix performance.
Bob Higgins reveals how the center of concrete becomes adiabatic—locking in heat and moisture—and why this defies common assumptions about water movement.
Bob Higgins breaks down how autogenous healing works in concrete—and why today’s rush for speed is killing its self-repair potential.
Bob Higgins explains how surface permeability is the weak link in concrete, letting in water, salts, and other materials that lead to long-term damage.
Concrete chemist Bob Higgins explains why slower, colder curing can lead to higher long-term strength—even if 28-day results look weak.
Most contractors think warm weather helps speed up a pour—but what if that early strength is fooling you? In this episode of the Concrete Logic Podcast, host Seth Tandett is joined again by concrete chemist Bob Higgins to break down the real effects of high temperatures on concrete strength, durability,…
What You'll Learn in This Episode: * Is your summer concrete secretly sabotaging long-term strength? * What actually happens to cement hydration when concrete gets too hot? * Can high early strength be misleading—and even dangerous? * Why is the surface of your slab the weakest link in hot weather…
Greg Fricks tells it like it is in this clip from Episode #124 of the Concrete Logic Podcast: if anything goes wrong with the concrete—cracks, delamination, color issues—the contractor gets the first call. Even if you followed the specs to the letter. And if you changed the design? Your liability…
In this jaw-dropping clip from Episode #124 of the Concrete Logic Podcast, Greg Fricks shares a real-world example of how a sudden Texas heatwave turned a solid concrete placement into a nightmare. If you're using a proprietary mix and don’t know how it reacts to extreme weather swings—you’re playing with…
Greg Fricks lays it out clearly in this clip from Episode #124 of the Concrete Logic Podcast: just because your one-year concrete warranty ends doesn’t mean you’re off the hook. That slab carries your name for the life of the building. Ignore a failure, and your brand pays the price.
In this clip from Episode #124 of the Concrete Logic Podcast, Greg Fricks warns contractors about blindly adopting proprietary concrete systems. What works in Chicago won’t always work in California. Before you sign up—or worse, pay an initiation fee—make sure you’ve done your homework on both the system and your…
In this short clip from Episode #124 of the Concrete Logic Podcast, Greg Fricks explains how concrete contractors slowly become numb to the massive risks they take on every single job.
Thinking about designing your own concrete slab—or taking on a proprietary system? You better know what you're signing up for. In this episode of the Concrete Logic Podcast, Seth Tandett talks with Greg Fricks, CEO of the Fricks Company, about the risks contractors face when they step into the design…

Seth spots what looks like a total finishing failure… but Dr. Jon explains why the lighting tells a different story—one that surfboard makers would understand perfectly.
Dr. Jon tells the story of a failed parking garage in Denver where a basic measurement error led to undersized columns, thin slabs, and a massive lawsuit. Yes, it really happened.
Concrete finishers are disappearing fast—and the industry’s not prepared. Dr. Jon and Seth talk about why this critical trade is wide open for anyone ready to build a career.
“Bad news doesn’t get better with time.” Seth and Dr. Jon reveal how ignoring floor issues early can turn into a contractor’s worst nightmare—fast and expensive.
Dr. Jon Belkowitz and Seth Tandett talk about the shocking costs of fixing bad concrete work. Think $20 per square foot is high? Try $200 when the lawsuits and experts show up.
A photo that looks like the surface of the moon—but it’s a warehouse slab. In this episode, Dr. Jon Belkowitz and Seth Tandett break down what went wrong, how these concrete disasters spiral into lawsuits, and why bad finishing techniques can cost $200 per square foot in repairs. Contractors, RMX…

Cold storage, ASRS, high racks—these aren’t jobs for cheap floors. In this clip, Lee Thrasher breaks down why high-performance concrete floors may come with a premium, but deliver big returns: fewer joints, leaner reinforcement, and better performance under pressure. Here's why it pays to invest.
Shrinkage compensating concrete claims to solve one of concrete’s biggest problems—cracking. But how far does it really go? In this clip, Lee Thrasher explains the science behind engineered expansion and what still needs to be done to make cracking a thing of the past.
