Pattison produces SHOULDER STONE in our state-of-the-art, jaw/cone crushing plant. Our crushing plant features compression crushing technology that limits fines generation and increase fractured faces.
Shoulder Stone Quality
We understand that source quality makes a significant difference in the longevity of aggregates. Our facility in Clayton, Iowa features 9 ledges that include ordovician dolomitic limestone, limestone and sandstone. Pattison SHOULDER STONE has been used in several projects conducted by Iowa State University. It has been designated as “high strength” stone and has demonstrated a longevity that exceeds most other quarry SHOULDER STONE.
