Wm. D. Scepaniak, Inc. is a diverse company specializing in different categories surrounding the Aggregate Industry.


We are one of the largest aggregate producers in the Midwest, processing more than 6 million tons a year and ranking as the 19th largest in the USA according to Pit and Quarry Magazine.  Here at Wm. D. Scepaniak, Inc. we strive everyday to get maximum production to make sure that we stay on or ahead of project deadlines.  We do this while still maintaining an excellent safety record and also preserving our quality controls.  This allows for both our customers and ourselves to have minimal issues when it’s time to haul the material onto a highway or other construction project for final placement.  Our crushing plants are some of the most modern and well maintained spreads in the industry today.  With our plants we have the ability to produce any road base, super pave, recycled material, or even just straight rock products.



We have a fleet of trucks that we use to haul gravel on state and county highway projects as well as different private projects.  Our truck fleet consists of identical modern international trucks pulling R-Way belly dump trailers or side dump trailers, all of which are identical.  We keep them identical to allow for ease of operation and maintenance.  We believe we are one of the most efficient short or long haul aggregate transporters in the upper Midwest.  If you are looking for an efficient, problem free, group of trucks to get the job done on time and hassle free, look no further than Wm. D. Scepaniak, Inc.


We have two portable high production wash plants that we use to wash anything from straight rock, straight sand, or a combination of both.  Most of the products that we produce with our wash plants are used to make concrete; whether it be concrete blocks, or for use in a basic concrete batch plant.  Washed material has many uses from back filling house foundations around drain tile, use on highway projects for pavement aggregate, to using washed sand for bedding of cattle.  If you have a need for washed material please let the professionals at Wm. D. Scepaniak, Inc. assist you with your project.
