Overview

Industrial Minerals & Aggregates covers the mining and quarrying of construction aggregates (crushed stone, sand, and gravel) and industrial minerals. At ~$29B in raw extraction it is led by aggregates majors (Vulcan Materials, Martin Marietta, CRH, Heidelberg Materials) operating thousands of local quarries and pits.

Aggregates are the quintessential local-monopoly infrastructure business — heavy and low-value relative to weight, they cannot be shipped far, giving quarries pricing power within their service radius. Demand tracks construction and infrastructure (with the IIJA a major tailwind), and pricing has been consistently strong. It is consolidating around scaled aggregates producers and a prized, durable, M&A-active infrastructure asset class.
