Base products are used to stabilize sub grade beneath asphalt and concrete paving, and commonly used for building parking lots and highways. Base rocks are designed to compact and create a hard, sealed surface. Con-Agg produces quality materials meeting MODOT specifications for Type 1, Type 5 base, and Type 7 base.


Clean or course aggregates consist of chips, 1” clean (#57), 2” clean, and 3” clean. Clean aggregates are typically used in the production of ready mix concrete or hot mix asphalt, chip and seal, pipe bedding, septic systems or to stabilize wet ground conditions. Smaller clean rock is also commonly used on driveways.

Road Rock

Road rock is used primarily as a surface application to county and state rock roadways, as this product is similar to base, but contains less fines and typically does not compact. Con-Agg offers road rock from ¾”, 1”, 1 ¼” and 2” top size, depending on volume of traffic on the roadway.

Rip Rap

Rip rap is large rocks that are well graded and clean for use along shorelines of rivers and lakes to help control erosion, drainage systems, and sediment. Con-Agg produces rip rap to meet various size specifications of MODOT, and some quarry locations produce rip rap meeting Corps of Engineer specifications.

Ag Lime

Agricultural lime is a key component to successful crop production. Ag Lime improves the physical, chemical, and biological properties of soil to maintain proper soil acidity. Excess soil acidity will negatively affect crop yield, profitability, and long-term soil productivity.
