Allama Iqbal International Airport

Challenge

Aviation safety standards, complex roof geometry, and phased work near active terminal operations.

Solution

PetroGrip APP membrane on main roof areas with polyurethane coating at drains, curbs, and detail zones.

Products: PetroGrip APP · Polyurethane Chemical Coatings

Substrate

Concrete roof decks and detail zones in the terminal infrastructure package

System build-up

1. Prepared and primed substrate
2. PetroGrip APP torch-applied membrane on main roof areas
3. Polyurethane chemical coatings at drains, curbs, and complex details
4. Protection / finishes per aviation package

Design rationale

APP membrane selected for heat/UV exposure on large roof planes; liquid polyurethane used where geometry made sheet detailing impractical.

Critical details

• —Phased work near active operations
• —Drain and curb interfaces
• —Lap continuity on main planes

Outcome

Waterproofing package delivered for the airport infrastructure scope as contracted.
