From Our Family to Yours: The Mid-States Legacy Since 1946

Our company was founded on May 13, 1946, by Charles V. Harker as Mid-States Concrete Products Co., built on a simple mission: deliver quality products, work hard, and treat people with respect. What began as a small, family-run operation in South Beloit, Illinois has grown into one of the Midwest’s most trusted producers of structural and architectural precast systems.

Over the decades, the company has remained under family leadership. Today, the Harker family - now in its third generation - continues to carry that vision forward, helping Mid-States stay true to its roots while driving innovation and growth across the region. And that is thanks to you – project partners who have trusted us with the responsibility of helping ensure your projects are successful from beginning to end.

From South Beloit to the Midwest and Beyond
Mid-States has grown from a single facility to a regional operation with manufacturing facilities in South Beloit, Illinois and Browntown, Wisconsin. We also recently expanded our capabilities by combining forces with International Concrete Products, based in Germantown, Wisconsin, a leader in architectural precast, and another family-led company. Together, we now offer complete structural and architectural precast solutions with greater capacity, more flexibility, and the same trusted quality our partners have relied on for generations.

Rooted in Values, Focused on the Future
No matter how much we grow, our approach stays the same. Every project deserves thoughtful planning, expert craftsmanship, and a team that listens. Our commitment is to keep communication clear from day one and guide you through every step of the process. With dedicated teams in estimating, design, engineering, production, and installation, we help ensure your project is efficient, high-performing, and built to last.

A Legacy Built to Last
For nearly 80 years, Mid-States has been family-led and values-driven. From the founding vision of Charles V. Harker to the Harker family's leadership today, our focus remains on building long-term partnerships, supporting our people, and delivering dependable precast solutions.

Greener Builds Start Here: Precast That Performs

How Precast Concrete Supports Smarter, More Sustainable Construction
Sustainability is about more than just materials. It’s about using systems that last longer, waste less, and reduce your carbon footprint. Precast concrete does all of that. It’s durable, efficient, and made in a controlled environment where waste is limited and quality is consistent. When used thoughtfully, precast helps buildings perform better for decades while minimizing environmental impact from day one.

Mid-States Concrete Industries and International Concrete Products share a commitment to sustainable building and strengthened that commitment when they joined forces in late 2023. Our structural and architectural precast systems are built to reduce waste, lower energy use, and last for generations. Together, we deliver high-performance precast that looks great and works even harder for people and the planet.

Why Precast Is a Better Material
Precast concrete is strong, efficient, and built to last. It’s produced in a controlled environment, which leads to higher quality, less material waste, and fewer delays on-site. Over time, it also reduces the need for repairs and maintenance, making it a reliable and cost-effective solution.

Precast supports green building goals and can contribute to LEED certification by improving:

  • Energy use, thanks to excellent thermal performance

  • Material efficiency, with reduced waste and regional material sourcing

  • Indoor air quality, due to stable temperatures and low emissions

 How Precast Reduces Carbon Impact

  • Less jobsite waste, because products are made to exact specifications

  • Improved insulation, helping reduce heating and cooling demands

  • Longer lifespan, which means fewer repairs and less material needed over time

Why Sustainability Matters
Choosing precast concrete is a powerful way to build more responsibly. It offers long-term benefits for your project and the planet:

  • Lower embodied carbon, thanks to efficient use of materials

  • Reduced energy consumption, due to natural temperature control

  • Cleaner construction, with less disruption and debris on site

Smart construction starts with smart materials. Precast gives you the performance and efficiency you need, with the environmental responsibility today’s projects demand.

Why Hollowcore Flooring Is a Smart Choice for Schools and Multi-Family Buildings

When it comes to building schools and multi-family housing, performance matters. You need materials that are strong, efficient, and built to last. And that’s exactly what hollowcore flooring delivers. At Mid-States Concrete Industries, we’ve helped educational and residential clients meet their design goals while improving long-term performance.

Here’s why hollowcore is a smart solution.

1. Span Longer, Build Smarter
Hollowcore slabs are designed for strength and flexibility. Their long-span capabilities reduce the need for support beams and columns, giving architects and engineers more freedom when designing gyms, classrooms, apartment layouts, and shared spaces.

  • Fewer interior supports

  • Faster installation and lower material costs

  • Ideal for wide, open layouts in schools and multi-family buildings

We’ve used hollowcore systems across a range of educational and multi-family projects to help create large, uninterrupted spaces that are both functional and future-ready.

2. Quiet Strength: Built-In Sound and Fire Protection
Sound control is essential in both schools and residential environments. Hollowcore naturally reduces sound transmission between floors, helping create quieter, more comfortable spaces for learning and living.

In addition to acoustic benefits, hollowcore provides excellent fire resistance, helping contain fire between units or floors and supporting safer building designs.

  • Meets sound control standards in educational settings

  • Helps reduce noise between residential units

  • Provides fire-rated floor assemblies for enhanced safety

  • Improves comfort and protection in classrooms, apartments, and common areas

Whether it’s student housing, apartments, or locker rooms, hollowcore makes a noticeable difference in both sound and safety.

3. Strength That Holds Up Under Pressure
Hollowcore slabs are built to handle heavy use. From gym floors and classrooms to high-traffic residential corridors and stair towers, hollowcore delivers strength without overbuilding.

  • Supports frequent use and live loads

  • Provides long-term structural performance

  • Keeps floor depth efficient without sacrificing capacity

Across our portfolio of education and multi-family builds, hollowcore continues to be a go-to solution for durability, versatility, and lasting value.

Build with confidence. Build with Mid-States.
Hollowcore flooring delivers the strength, efficiency, safety, and long-term value today’s schools and multi-family buildings demand. If you're ready to explore smarter solutions, our team is here to help you get started. Contact us today at sales@msprecast.com.

The Truth About Precast: 4 Misconceptions Explained

At Mid-States Concrete Industries, we hear the same questions pop up time and time again. Is precast too expensive? Isn’t it just for parking garages? The truth is, precast concrete is more efficient, flexible, and cost-effective than many people realize.

Let’s clear up a few of the biggest myths.

  1. "Precast is too expensive."
    At first glance, it might seem that way. But when you consider the full project timeline and long-term value, precast often ends up saving money. It reduces labor costs, shortens the construction schedule, and keeps waste to a minimum. Because it’s made off-site in a controlled environment, installation is faster and more predictable. Less labor. Fewer delays. More control. That’s a smarter investment.

  2. "Precast is only for parking garages."
    Precast is ideal for garages, but that’s just the beginning. At Mid-States, we’ve supplied precast for schools, fieldhouses, mixed use buildings, manufacturing facilities, and more. Whether you need wall panels, hollowcore flooring, or an entire building, precast fits a wide variety of spaces. It’s strong, flexible, and built to perform wherever you need it.

  3. "Precast can’t be customized."
    Precast offers more design flexibility than most people think. Need a specific texture, finish, or pattern? We can do it. From Graphic Concrete and form liners to custom staining and finishes, we work with design teams to make sure the end result reflects the original vision, without compromising on performance. Precast is anything but one-size-fits-all.

  4. "Precast is hard to coordinate with other trades."
    With early involvement and clear communication, precast becomes one of the easiest systems to manage. Our Face-to-Face Solution helps align everyone from day one. We collaborate with architects, engineers, and contractors to make sure our pieces fit smoothly into the overall plan. The earlier we’re brought in, the better precast performs on your schedule.
