Indira Gandhi International Airport, New Delhi

Since 2015, LN Petrochem Pvt Ltd has been the sole-source supplier of FRSS Stiffcoat for rigid (concrete) pavement thin resurfacing at Indira Gandhi International Airport (DEL), India's busiest airport, handling ~78 million passengers in 2024 across four runways and 1,200+ daily aircraft movements.

The relationship began in 2013, when FRSS Stiffcoat was introduced as a trial system. GMR Delhi's engineers monitored performance through two full years of extreme climate cycles before committing budget, leading to the first confirmed order in 2015. Since then, LN Petrochem has been re-specified every year, without competitive re-tendering of the technology.

FRSS Stiffcoat is a US-developed thin-overlay system purpose-built for concrete airfield pavement — bonding directly to concrete, sealing joints against fuel and moisture and applied cold with no specialized plant. It reopens to traffic in under 4 hours, fitting GMR Delhi's night-shift closure windows.

Versus European and South Korean alternatives, it costs 3–5x less with no comparable long-term field record. Bays from the earliest years remain in service after 10+ years, without debonding, raveling, or joint failure — a track record spanning 2013–2026 across Terminal 1, Terminal 2, aprons and the taxiway network.
