Aggregate Materials
We design and produce limestone, sand, and gravel products to meet their intended uses—for public or private projects—and customers rely on our expertise in quality.
Gerken produces high-quality limestone products in Ohio at The Custar Stone Co., the Gerken Materials, Inc. West Millgrove location, and The Bluffton Stone Company. In addition, all locations offer numerous non-limestone aggregate products. And The Bluffton Stone Company produces a flagstone with a unique color and composition suitable for various landscaping projects.
Our Clinton, Hillsdale, Jonesville, Round Lake, and Tecumseh Gerken Materials locations in Michigan offer natural, washed, crushed, and processed sand and gravel materials.
Gerken’s Ohio-produced limestone products are occasionally available at one or more Michigan locations.
Please contact each location for current product inventory information.
We offer products that are Ohio and/or Michigan Department of Transportation certified and approved.
