Kuala Lumpur runway

Despite preconstruction soil treatment, the runway at the klia2 passenger terminal at Kuala Lumpur International Airport in Malaysia, opened in 2014 to service low-cost flights, is sinking due to unstable soil, causing bumps, cracks and the pooling of water. 

This has led to flight delays and may contribute to airplane damage. AirAsia, which operates the largest fleet flying out of klia2, has sued the airport’s operator for losses and damage. It is estimated that it will take five years for the issues to be resolved.
