From the Ground Up
Whetstone Quarry is where Callaway Material's limestone products start — extracted, processed, and quality-checked before they ever leave our site. Controlling the production ourselves is what lets us guarantee consistency on every aggregate load we supply, across the full range of limestone products we offer.
Whetstone Quarry still has significant room to grow, and we plan on adding more products, more capacity, and supporting new applications as growth continues to expand across Missouri.

Powering Our Asphalt Plant
Our limestone quarry doesn't just supply limestone products directly — it also feeds material into our Fulton Asphalt Plant. Producing our own aggregate for our own asphalt means fewer outside suppliers, fewer middlemen, and fewer added costs along the way. That streamlined operation is exactly what lets us keep pricing competitive without cutting corners on quality.
