What Stego Industries, LLC does

Stego Industries, LLC is a privately held U.S. manufacturer of below-slab vapor barriers and retarders, founded in 1998 and headquartered in San Clemente, California. The company's core technology is multi-layer plastic extrusion using proprietary blends of prime virgin polyolefin resins, producing products such as Stego Wrap (15-Mil, 20-Mil, 10-Mil Class A/C) with documented water vapor permeance ratings that exceed ASTM E1745 standards. Stego has organized its portfolio into sub-brands targeting distinct segments: Stego Wrap for commercial below-slab applications, StegoHome for residential, StegoCrawl for crawl space encapsulation, Drago Wrap for VOC and soil-gas barriers on brownfield sites, Pango Wrap for physical termite barriers, and Beast for concrete accessories compatible with Stego Wrap. The 2024 acquisition of Multi-Panels Inc. added high-performance cementitious MgO panels to the portfolio.

The company makes money through one-time product sales across commercial, residential, specialty, and accessory lines, with no subscription or recurring component. Distribution is hybrid: direct sales through nationwide full-time technical sales managers for enterprise commercial projects, a global distributor network for broad availability (the website provides a 'Find a Distributor' tool), and a direct e-commerce shop targeting DIY homeowners and small contractors. Go-to-market is anchored on a specification-driven model that delivers over 500 AIA-registered continuing education seminars per year to architects and design professionals, embedding Stego specifications into construction documents. Products are specified and sold in 55+ countries and territories worldwide.

Stego operates as an independent, founder-led private company under CEO Paul Blasdel, with no disclosed outside investors or parent entity. Self-described as the most widely-specified below-slab vapor barrier in North America, the company has built a 20+ year track record and a first-of-its-kind Life of the Building Warranty. The company serves a diversified base of commercial contractors, residential builders, homeowners, architects and engineers, distributors, and environmental engineers working on brownfield redevelopment.
