Services
Methane Mitigation Systems
Custom methane mitigation systems prevent gas migration in landfills and industrial sites. Our solutions include passive/active venting, soil gas barriers, and sub-slab ventilation. Systems comply with LA Department of Building Safety and DTSC regulations while ensuring construction safety and permit approval.
Radon Reduction Systems
Active sub-slab depressurization systems and soil gas barriers mitigate radon exposure in residential and commercial buildings. We follow EPA Zone 1 guidelines and HUD standards, incorporating continuous monitoring to reduce lung cancer risks in high-radon areas.
Vapor Intrusion Mitigation
Real-time telemetry monitoring detects volatile organic compounds (VOCs) in soil gas. Our vapor barriers and ventilation systems protect schools, hospitals, and residential developments from chemical vapors, ensuring compliance with environmental protection agencies.
Brownfield Redevelopment
Comprehensive brownfield redevelopment includes environmental site assessments, remediation planning, and vapor intrusion mitigation. We transform contaminated properties into compliant commercial/residential sites, securing regulatory approvals and redevelopment incentives.
Telemetry Monitoring Systems
24/7 telemetry systems provide automated alerts for methane, radon, and VOCs. Cloud-based data logging ensures regulatory compliance with real-time access for stakeholders, integrating FACP systems and Telguard TG-7 cellular communications for continuous site safety.
