Aggregates are the foundation of HAMM Companies

For over 60 years, our quarries have been a reliable producer of construction aggregates used in a myriad of applications. From subgrade to surface, each layer of HAMM aggregates meet all standard requirements, creating the safest and most stable foundation for any construction project. Our quarries across Northeast Kansas hold native limestone rock, which is extracted and processed into a variety of specific aggregate products.

Commercial & Residential

Aggregates in standard and specialty blends are available for residential, commercial, industrial, and municipal use. Our experienced sales staff will calculate the volume required for each unique project, providing fast, on-time delivery directly to your project site by our company-wide fleet of vehicles.
