Environmental Containment Corp

What Environmental Containment Corp does

Environmental Containment Corp (ECC) is a privately held, Seattle-based manufacturer and contractor specializing in the design, production, and installation of precast concrete stormwater containment systems for land development, commercial construction, and railroad infrastructure projects in the Pacific Northwest. Founded in 1994, the company markets itself as a single-source provider of structural and architectural precast products, including box culverts, detention vaults (cast-in-place and precast), and stormwater retention systems. The company is led by CEO & Partner Ron Sparks, who has 29 years of industry experience and currently chairs the National Precast Concrete Association Board. The business operates through three wholly owned sub-brands: National Precast (precast concrete manufacturing since 1974), Superior Concrete (general contractor for foundation, forming, and site work with 22+ years in operation), and Marks Metal Technology (Oregon-based metal fabrication acquired in May 2023, founded in 1946). Together these form what the company calls its Family of Brands.

The company's revenue model is hardware sales through project-based contracts with construction firms, land developers, and infrastructure project teams, with pricing provided via quote-based estimation rather than published rate cards. Distribution is direct sales-led through regional managers and senior sales representatives, supported by content marketing, social media presence, and website lead capture. Technical differentiation rests on a vertically integrated precast manufacturing operation with certifications including PCI Level I/II, NPCA Master Precaster, and multiple ACI credentials held by the Facilities General Manager. Customer segments are primarily land development companies, with railroad infrastructure identified as a secondary vertical served by a dedicated Product Specialist.

The company's expansion posture is evidenced by the May 2023 Marks Metal Technology acquisition, the introduction of Marbled Precast architectural products, and the formalization of a railroad product line. Its operations remain geographically concentrated in the Pacific Northwest, with the company describing itself as the largest one-stop-shop stormwater runoff containment provider in that region. Ownership is concentrated among founders and partners with no disclosed institutional or private equity backing.
