MARKETS & EXPERIENCE
RTI delivers envelope-critical sealant, waterproofing, expansion joint, firestopping, and protective coating systems on projects where performance, compliance, and schedule certainty matter. RTI is trusted on high-accountability environments where envelope failure is not an option and where clean close-out is critical to occupancy and turnover. With decades of combined experience and a stable, relationship-driven workforce, RTI supports general contractors on complex, schedule-sensitive projects across multiple market sectors.
RTI has experience working in active, high-security aviation and transportation environments where coordination, sequencing, and compliance are critical. Work is executed with an understanding of operational constraints, inspection requirements, and tight turnover windows.
