Pattison CLEAN CHIPS are produced using a variety of Ordovician limestone types located throughout the Pattison Quarry. Because of the number of uses for this material, it is manufactured to a variety of sizes and desired physical properties. CLEAN CHIPS are dry screened and do not contain fines increasing aggregate permeability. This results in an excellent bedding material that reduces absorption and resists freeze/thaw degradation.

specified sizes of fractured limestone and to a specific desired set
of physical properties. Clean stone is dry screened and does not contain fines.

CLEAN CHIPS are also known as pipe bedding, clean rock, porous backfill, porous fill, chips, bedding stone, drain rock, underlayment, base material, pothole repair stone, and clean chips. Pattison produces CLEAN CHIPS products in our state-of-the-art, jaw/cone crushing plant. Our crushing plant is built around a sophisticated compression crushing technology that reduces fines generation and increase fractured faces.
Where are Clean Chips Used
Pattison CLEAN CHIPS are used as an underlayment, pipe bedding, and road base. It is used in drainage fields, walkways, construction projects, and landscaping. CLEAN CHIPS are loaded for shipping with our direct to rail transfer system. As a result, products move quickly from production to rail with minimal handling, dramatically reducing product degradation and loading costs.
Clean Chips Production
This material is commonly ordered in specific sizes and physical properties. Because of this, we harvest material from a variety of Ordovician Dolomitic Limestone ledges within our quarry to meet specific requirements. Pattison’s stone products are sourced from a variety of very high quality ledges, each with specific properties. Limestone extracted from these ledges contains minimal deleterious material, and performs exceedingly well on multiple quality assurance tests.
Pattison CLEAN CHIPS meet the quality usage designations in the states of Iowa, Missouri and Minnesota. Here’s what Wikipedia has to say.
More about 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.

State of the art Aggregate Plant
Pattison’s newly installed Cone Crusher and production plant is state-of-the-art, producing some of the highest quality Ordovician Dolomitic Limestone CLEAN CHIPS.
Material is separated into various required sizes without inducing fractures, while yielding a refined individual rack shape that is the most desirable for tight compaction and stability. Pattison’s new aggregate plant produces CLEAN CHIPS of exceptional quality.
Logistics second to none
Pattison recently completed its Rail Spur project, extending multiple rail lines directly into our new state-of-the-art aggregate production plant!.
Pattison’s advanced direct to rail loadout system coupled with the Pattison rail spur allows aggregate products to be loaded directly from the production plant on to enclosed rail ore cars for delivery. Eliminating excess handling saves costs, and insures a higher quality product.
