Stewart Materials is a privately held, Florida, aggregate material products company. Since 1982, it has evolved to become one of the largest suppliers of inland sourced, process-controlled materials in the state of Florida. They enhance Florida life. Responsibly.

"When people think about walking the beach, blasting a golf shot from a bunker or driving an interstate or roadway, aggregate materials don’t come to mind. All these things are made possible, in part, because of aggregate material processing."

Nick Stewart, Chief Executive Officer

Materials supplied by Stewart Materials go directly to enhancing Florida’s nearly $70 billion annual tourism industry. These products enhance and renourish Florida beaches and golf courses, supply aggregate for roadway and other construction, and are used in projects as diverse as athletic fields, state and federal parks, wildlife habitats and the Herbert Hoover Dike.

Core Purpose:

Research, develop and safely recover Florida’s natural resources.

Reliably supply Florida-sourced, process-controlled material products.

Responsibly, sustain and enhance Florida’s environment, industries and infrastructure.

Leave a better Florida for future generations.


Stewart Materials currently supplies an array of specialized materials for municipal, quasi-municipal and governmental, agencies and private entities throughout the state of Florida.

Stewart Materials’ process-controlled custom products meet diverse customer requirements and specifications. Nowhere is Stewart Materials’ ability and proficiency more beneficial than in the beach renourishment domain.


Beach renourishment is an expertise of Stewart Materials. The company is widely acknowledged as the thought leader and a reliable supplier of inland sourced materials for large-scale renourishment projects. Stewart Materials earned its stellar reputation by consistently supplying large volumes of custom sands for complex renourishment projects up and down Florida’s coastline.

As our beaches go, so goes Florida. Beach renourishment is a vital element in Florida’s nearly $70 billion annual tourism industry’s success. For many Florida Beaches, Stewart Materials’ inland sources are a cost efficient, environmentally and functionally superior alternative to traditional offshore sources. Functionally, the quality of sand recovered from offshore borrow sites is often inconsistent and incompatible with the sand it is intended to replace or renourish. This is in stark contrast to Stewart Materials’ inland sourced, process-controlled materials.

Stewart Materials green and responsible material processing practices yield customizable sands to meet the needs of agencies, associations, municipalities, private landowners and beachgoers for varying type and consistency sands.

Success Studies


Collier County

In just one recent example, Stewart Materials’ 2013 Collier County Beach Renourishment project finished ahead of schedule. Stewart Materials was required to facilitate the project start to finish within the critical November 1st – March 31st window for nesting sea turtles.

The successful project set the stage for what Stewart Materials Founder Nick Stewart sees as the blueprint for successful ongoing beach renourishment projects—an initial, foundational large scale renourishment which gives way to future, smaller annual and bi-annual scheduled maintenance renourishment projects.

Green Practices

Once a site completes its operational lifecycle as a material source, it immediately and seamlessly transitions to a green and aquatic “blue” space. Over time these green and blue spaces become natural habitats for fresh water fish and indigenous plant populations. Having completed its operational lifecycle, Stewart Materials’ very first site now stands as a water retention, green and blue space in Ft. Pierce, Florida. Custom materials processing is fundamentally a temporary land use.

Stewart Materials extracts materials in an environmentally safe, repeatable, low-impact manner, using only responsible, green mining practices. Stewart Materials continually evolves to develop new and improved methodologies. The company’s in-house geologist works closely with a team of hydrogeology and restorative ecology professionals, as well as regulatory policymakers.

Material extraction and processing are subject to a stringent regulatory structure, encompassing local, state and federal government. Local government regulations focus on land uses related to managing growth, protecting natural resources and managing public safety and health. In part, state regulation addresses effects on water quality and quantity, impacts on wetlands, safe reclamation, and post activity clean up and state protected wetland dependent wildlife species. State regulation also solicits input from agencies, including Florida Fish and Wildlife Conservation Commission and the Department of State Division of Historical Resources.
