PUTRAJAYA: The water leakage at Kuala Lumpur International Airport (KLIA) Terminal 1 was caused by a contractor’s error during roof repair and waterproofing works, says Malaysia Airports Holdings Bhd (MAHB).
Initial investigations found that the incident on Friday occurred while major roof rehabilitation work was being carried out.
The contractor had been sealing and covering drainage channels on the roof when lightning activity intensified around the airport, MAHB said.
“In the rush to clear the area due to worsening weather conditions, the contractor failed to remove the plywood boards that were used as temporary covers for the drainage channels. This resulted in one of the roof drainage systems becoming blocked.”
The blockage prevented heavy rainwater from draining, causing a significant accumulation of water on the rooftop. The pooled water eventually seeped through, leading to a ceiling leak that affected parts of the departure hall.
MAHB said its ground response team managed to clean up and secure the affected area within an hour and a half.
