What Advanced Construction Technologies does

Advanced Construction Technologies (ACT) is a private, design-build environmental mitigation specialist founded circa 2000 and headquartered in Irvine, California, with a secondary office in San Ramon, CA. The company designs, installs, and monitors systems that protect buildings and occupants from methane gas, soil VOC vapor intrusion, radon, and other subsurface environmental hazards, serving residential, commercial, industrial, institutional, and brownfield redevelopment clients across 25 U.S. states. ACT operates with a fully in-house, multi-licensed workforce (professional engineering, electrical, plumbing, and general contracting under CA license #797379 A, B, C-36) and explicitly avoids third-party subcontractors, enabling design-to-install integration on a single unified team.

The company's core technology portfolio includes HDPE methane and VOC vapor barriers, real-time gas detection systems with FACP and Telguard TG-7 cellular telemetry, a proprietary in-house testing laboratory, and 24/7 monitoring/maintenance services. Over 25+ years, ACT has completed 2,100+ projects protecting 70M+ square feet of property. Revenue is generated through project-based design-build fees for environmental engineering services, turnkey installation, and a recurring monitoring/maintenance subscription stream. In 2025, ACT joined the FullTerra family of environmental mitigation companies, positioning the brand alongside sister companies (GeoKinetics, Elite Radon Team, Clean Vapor, Midwest Barrier) to deliver nationwide coverage across all 50 states.
