Pattison Aggregate Products

Pattison Sand Company produces high quality aggregates for the construction industry.   With rock, age matters and Northeast Iowa has bountiful resources of some of the oldest stone in the Midwest, with nearly 750 acres of land, the Pattison Quarry is comprised of Ordovician stone producing high quality dolomitic limestone.

Pattison rock products receive the highest ratings available from the Federal Highway Administration, Iowa Department of Transportation, and others, for use in the construction industry.  This high quality stone is used for concrete, asphalt, secondary roads, erosion control, base stabilization and even mixed with salt for traction control.

Ordovician Dolomitic Limestone

When it comes to rock, age really matters.  Ordovician Dolomitic Limestone is some of the highest quality, hardest and most durable anywhere in Iowa. Ordovocian formations are only found in the northeast portion of Iowa. Pattison’s Clayton, IA quarry site is right in the middle of it.

Certified by multiple Departments of Transportation, and the FAA.

Exceptional Quality Certified Aggregates

Pattison aggregates are sourced from our Clayton IA Ordovician Quarry.  Material is extracted from 9 ledges offering various superior properties that can be selected based on specified parameters, yielding the highest performing aggregate for the task.

Our Ordovician Dolomitic Limestone Quarry Geology

Pattison sand company state DOT spec Aggregate formations

Geologic age matters when it comes to aggregate physical properties. Older rocks are generally more competent and less absorptive for various applications such as Portland Cement Concrete Stone and Bituminous Asphalt Stone. During initial development of our long-term quarry operations, we will be mining the Oneota and Shakopee Dolomites. These represent superior grade State DOT specification aggregate. They are desirable for concrete stone, asphalt stone, manufactured sand and rip rap. In fact, Iowa DOT has developed a specific quality characteristic for Oneota manufactured sand because of its physical and geological properties.

Pattison has received approval from the State of Iowa DOT and is working on certifications from neighboring states including Illinois, Minnesota, Missouri, Nebraska, North Dakota and Wisconsin. The same is true for the various Army Corp of Engineers Districts in and around Iowa. We have received FAA certification for airport runway construction projects.
