The Jurgensen Companies are a leading producer of construction aggregates in Ohio, Indiana, and Kentucky. We sustain the communities in which we operate by providing the material needed for quality of life. There are 16 operations that primarily produce crushed stone, sand and gravel. Whether the project is a school, bridge, or stadium, aggregate is used to get the job done.

Jurgensen Aggregates operate distribution facilities throughout Ohio, Indiana, and Kentucky. Our Companies include:

Our aggregate products are used in a wide variety of construction applications including asphalt and concrete, residential and commercial, and agricultural and environmental purposes. Our products range in size from rip rap, large stones used for erosion control, to ag lime, a fine dust used by farmers to neutralize soil acidity.

Aggregates are sold by size, and production techniques include blasting, dredging, crushing and screening to meet our customer’s needs. Our quality control labs monitor and test our production materials to verify quality and gradation. We are also a prime source for calcium carbonate fillers that are produced at one location (Piqua Materials) by pulverization and air classification techniques. These fillers are widely used in mastics, fiber-reinforced plastics, and many other applications. Jurgensen Aggregates continues to grow its operations by adding the latest technology and equipment available. Our team is well trained and firmly committed to excellent customer service and satisfaction.

Agricultural Lime


As fertilizer, seed and other costs associated with planting increase, it is important that you – the farmer – get the most out of your crops. From corn to soybeans to wheat or alfalfa, it makes sense to want the highest yield by having the correct soil. Testing your soils regularly and applying the proper amount of agricultural lime to your fields will help guarantee a successful harvest.


We supply lime to you in 50 lb. bags or via bulk loadout. We are centrally located just minutes from I-75 and I-70. Melvin Stone and Piqua Materials load dump trucks, dump trailers and even specialty ag lime spreaders.

  • Piqua Materials Chemical Analysis: Calcium 34.20% Magnesium 2.37% Iron Oxide .58% Silicon Dioxide 2.74% Effective Neutralizing Power (ENP) 79.4% Total Neutralizing Power (TNP) 97.1%
  • Melvin Stone Chemical Analysis: Calcium 21% Magnesium 12% Effective Neutralizing Power (ENP) 78.25% Total Neutralizing Power (TNP) 105.1%


Our lime is 100% natural and not a byproduct. Using ag lime appropriately is one of the most important running efforts in successful production. Excess soil acidity is a primary constraint to high, profitable yields and long-term soil productivity. Ag lime improves the physical, chemical and biological properties of soil. It also improves symbiotic nitrogen fixation for legumes, influences the availability of plant nutrients and reduces mineral element toxicities.


Industrial Minerals

Our industrial minerals product lines include finely pulverized products with a median particle size from 18 microns all the way down to 3 microns which are available in fifty-pound bags, 2000 pound super sacks, or in bulk pneumatic trailer loads.

Many of our products enhance the performance of adhesives, vinyl flooring, carpet backing, drywall compound, automotive sealers, and concrete sealants.

Started in 1865, Piqua Minerals is an expert in the manufacturing of pulverized 100% natural high calcium low magnesium lime. Conveniently located in the center of the industrial Midwest, Piqua has a strong commitment to superior customer service and product support.

Our Industrial products are available at Piqua Materials.

Recycled Concrete


Concrete recycling is becoming a popular way to utilize aggregate left behind when structures or roadways are demolished. In the past, this rubble was disposed of in landfills, but with more attention being paid to environmental concerns, concrete recycling allows reuse of the rubble while also keeping construction costs down.

The Jurgensen Companies are committed to sustainability. We take pride in producing recycled products that are not only environmentally friendly but also high quality and ready for construction use. Contact one of our salesmen for more information.

Our recycled concrete is available at Wooster Materials, Enon Sand & Gravel and Valley Asphalt Corp. Plant 14, Valley Asphalt Corp. Plant 17, Valley Asphalt Corp. Plant 23, Valley Asphalt Corp. Plant 28, Eaton Asphalt Plant 1 and Eaton Asphalt Plant 3.
