SRM Concrete

SRM Concrete is the largest family-owned ready-mix concrete manufacturer in the United States. Founded in 1999 by Mike and Melissa Hollingshead with a single backyard plant and three trucks, the company now employs more than 8,500 people and operates across 24 states. Growth has been driven largely by acquisitions, with over 100 completed since 2012, and the business is led by CEO Jeff Hollingshead.

The company is vertically integrated across construction materials. Its core ready-mix concrete business runs 563 plants, supplying residential, commercial and large-scale development projects. Supporting operations include SRM Materials, with 33 quarries producing aggregates; Hollingshead Cement, which operates 12 cement terminals feeding the ready-mix supply chain; and Hollingshead Harbor, which handles materials logistics and distribution.

Employment therefore spans concrete manufacturing and delivery, aggregates production, cement terminal operations and maritime logistics, as well as commercial and customer-facing roles. The company states that it is family-owned and family-values driven, and lists five cultural principles: Safety, Quality, Kindness, Cleanliness and a go-getter mentality.
