The Concrete-Lifting Chronicles

Spray Foam Magazine – Show 2026 – Jeremy Leman came of age in the spray foam industry after purchasing a beat-up old rig fresh out of high school. The year was 2004 during a frigid January in Illinois, and young Jeremy started what would become Sealtite Insulation & SlabJacking with little more than work ethic and a prayer. Flash forward 21 years later, and he’s seen the fruits of his labor lift himself and those around him ever-higher with each passing year. He credits his company’s success to his faith in God, with long days spent spraying, and even more nights spent praying.

Jeremy now leads a team of 28-strong, with a main branch operating in Fairbury, Illinois, and another down in Fort Myers, Florida. He’s got a fleet of 10 rigs across both Sealtite branches: four each for foam and slabjacking, plus two for cellulose. His journey may have started with spray foam insulation, but the company’s risen to new heights by expanding into concrete lifting markets, also known as slab/polyjacking. Cracks and settling hate to see Sealtite coming.

A building is only as stable as the foundation it rests on, and slabjacking can right many a faulty foundation. But doing it well requires the operator to have a keen eye and an exacting touch. Controlling the foam as it spreads through unseen underground voids without over/under lifting or further cracking compromised concrete is no small task. One slight miscalculation creates costly mistakes, and it’s not something Jeremy ever takes lightly.

Fortunately, Jeremy rarely meets a slab too complex or weighty to lift and stabilize. After Hurricane Ian ripped through the coastal south in 2022, Sealtite’s Florida branch responded to a dire call. The hurricane destroyed the seawall near a client’s home, and a neighboring home had already been swallowed up by the stormy sea. Determined to prevent his client’s home from slipping toward the same fate, Jeremy instructed his team on how to best stabilize the battered home, saving it from certain destruction.

The most challenging jobs are the most gratifying to get right. A seemingly straightforward gig involved injecting foam beneath a two-car garage. A piece of cake, had the foundation not been sitting right on top of a city sewer line! The hair-thin margin for error was a recipe for a smelly disaster and a major liability. Less experienced operators may have balked, but not Jeremy. He and his team successfully lifted the garage’s entire foundation two and a half inches– crushing the job, but not the sewer line.

Harrowing jobs make good stories, but it’s the mundane that keeps bread on the table. Sealtite has lifted a lion’s share of pools. Under Jeremy’s guidance, they’ve lifted large and leisurely spaces like in-ground pools with attached spas. They’ve also stabilized spaces much smaller and more sacred, such as the baptismal pool from a long-settled church foundation. The baptismal job held a special significance for Jeremy, who serves as a minister at his community’s church.  

Outside of Sealtite and his ministerial duties, Jeremy is a husband and a father of eight (four boys and four girls). For him, the intersection of faith and service is what his career’s all about. He knows the best is yet to come, so long as he keeps his eyes on the skies and his feet on stable ground.

As Spray Foam Magazine proudly recognizes Jeremy Leman as our 2025 Concrete Lifting Contractor of the Year, we celebrate not only his technical precision and fearless problem-solving, but the integrity and faith that anchor everything he builds. From a single worn-out rig in Illinois to a multi-branch operation lifting homes, pools, and entire communities, Jeremy has proven that strong foundations—both concrete and character—are what truly elevate this industry. Congratulations, Jeremy, on a well-earned honor and for continuing to raise the standard for concrete lifting professionals everywhere.
