What Earth Tech Enterprises does

Earth Tech Enterprises, Inc. is a Fort Myers, Florida-based heavy civil site contractor serving residential developers, commercial builders, municipalities, and resort operators across Southwest Florida. The company is structured around four integrated service lines: site development (surveying, grading, utilities, roadworks, land clearing, lake excavation, environmental restoration), marine construction (dredging, docks, seawalls, pile driving, shoreline stabilization), mining operations at the 502-acre Bell Mine (FDOT-approved base rock, washed and unwashed aggregate, rip-rap, with 8M tons of fill dirt and 27M tons of aggregate reserves), and crushing/recycling (~150,000 tons of concrete processed annually). Its technical stack comprises a modern heavy civil fleet equipped with GPS and universal total station (UTS) grade control, OEM telematics, and payload tracking systems that support precision grading, operational visibility, and FDOT-spec QA/QC.

The company generates revenue through project-based contracts awarded via competitive bidding on public works and negotiated agreements with private developers, with material sales priced per ton or unit and overall pricing quote-based and not publicly disclosed. Its customer roster includes national homebuilders (U.S. Homes, Pulte Group, D.R. Horton), municipal clients (Collier County, City of Naples, Longboat Key, Marco Island), industrial customers (Cemex), environmental organizations (Audubon Society), and resort operators (South Seas Island Resort). Marketing is primarily direct and relationship-driven, supplemented by case studies and organic social presence on Facebook, Instagram, and LinkedIn.

Earth Tech was founded in 2000, originally as a small paving operation, and was acquired by Seagate Development Group in December 2021. Under Seagate ownership, the company has invested tens of millions of dollars in fleet modernization, completed the $15.3M acquisition of Bell Mine in 2022, and tripled annual revenues over the two years following the acquisition. The company is led by CEO James A. Nulf, Jr. and President Chris Gehring, with a management team organized around site development, mining, marine construction, finance, HR, and business administration.

Core offering

Earth Tech Enterprises is a full-service heavy civil site contractor providing vertically integrated site development (land clearing, grading, utilities, roadworks, lake excavation), marine construction (dredging, seawalls, pile driving, shoreline stabilization), public/special projects (beach renourishment, dune restoration, hurricane recovery, coastal resilience), and aggregate supply. The company owns and operates Bell Mine, a 502-acre aggregate operation producing FDOT-approved base rock, aggregate, and rip-rap, and runs an in-house concrete/aggregate crushing line processing approximately 150,000 tons per year.

Product overview

Earth Tech Enterprises is a full-service heavy civil site contractor offering integrated solutions through three core divisions: Site Development, Marine Construction, and Mining Operations (which includes Crushing). The company provides vertically integrated services spanning site development (land clearing, grading, utilities, roadworks), marine construction (dredging, piers, seawalls, shoreline stabilization), mining operations (exploration, drilling, blasting, haulage), and crushing/recycling. The company operates Bell Mine, a 502-acre mining asset with significant aggregate reserves, which supplies both Earth Tech's own projects and external customers. Services are delivered through a vertically integrated model with an in-house fleet and workforce, enabling the company to self-perform work and control material supply for competitive pricing.

Others

• CEMEX, S.A.B. de C.V. Global building materials company that is both an Earth Tech customer (dredging services) and a supplier-side comparable in aggregates and ready-mix. Relevant as a major materials counterpart in the Florida market.

Direct peers

• Sterling Infrastructure, Inc. Public specialty contractor in heavy civil, site development, and transportation infrastructure. Sterling's E-Infrastructure Solutions segment overlaps directly with Earth Tech's site development, utilities, and grading services for residential and commercial developers.
• Construction Partners, Inc. Public heavy civil and site preparation contractor operating across the Sun Belt with integrated hot-mix asphalt plants and aggregates. Closely comparable to Earth Tech's vertically integrated site development + aggregates + paving-adjacent model, especially in Florida-focused geographies.
• Vecellio Group / Ranger Construction: Florida-headquartered heavy civil, site development, and mining/materials contractor. Overlaps directly with Earth Tech on site development, marine, and aggregate supply in the Florida market, particularly for FDOT and residential work.

Broad incumbents

• Granite Construction Incorporated: Large-cap public heavy civil contractor with materials (aggregates) operations nationwide. Comparable in that it pairs site development with vertically owned aggregate reserves, though at far greater scale and geographic breadth.
• MasTec, Inc. Large public infrastructure services contractor with utility, oil & gas, and clean energy & infrastructure segments. Comparable for site development capabilities for utility-scale and infrastructure projects, though much broader and larger.
• Martin Marietta Materials, Inc. Large-cap aggregates producer with operations across the U.S. Southeast. Comparable for aggregate economics, FDOT-spec base rock production, and the role of vertically integrated materials in heavy civil contracting economics.
• Vulcan Materials Company: Largest U.S. producer of construction aggregates, with significant Florida operations including sand, gravel, and crushed stone production. Comparable to Earth Tech's Bell Mine aggregates business as a benchmark for aggregate supply economics.

Regional players

• Anderson Columbia Co., Inc. Major Florida-based heavy civil and paving contractor with its own aggregate pits and asphalt plants. Direct competitor in SW Florida site development, road building, and aggregate supply for the same residential developer customers.

Emerging players

• Wright Construction Group: Florida-based site work and underground utilities contractor serving residential and commercial developers. Comparable to Earth Tech's site development division in scale, customer profile, and SW/Florida geography.
