Airport operator uses new method to fix klia2’s taxiways

MAHB is using grouting injection to replace the installation of precast slab for taxiways and parking apron. – The Malaysian Insider filepic, November 6, 2015.

Malaysia Airports Holdings Bhd (MAHB) has found a new method of maintenance, using grouting injection to replace the installation of precast slab for taxiways and parking apron, at the Kuala Lumpur International Airport 2 (klia2) in Sepang.

MAHB said the grouting was piloted at the affected locations last month as part of its continuous improvement effort.

"This new method will not involve open excavation works and therefore, will result in less disruption to airport operations."

MAHB said 54 locations needed long-term solutions to address soil settlement issues in klia2, particularly on taxiways (12 locations) and parking apron (42 bays).

"As at October 31, 35 locations have been installed with precast slab, while moving forward the remaining 19 locations will be maintained with grouting injection method."

However, it said the work schedule remained unchanged and works for remaining locations would be complete in April next year as reported.

He said the pavement overlay works involved 19% of the total 1.48 million sqm klia2 airport area and until October 31, 84% of the job had been completed.

"The percentage of the area to be maintained with pavement overlay works will reduce over time from 19% in 2015, tapering to a minimum of 5% by 2019.

MAHB said it valued strong engagement with all stakeholders through the joint inspection committee, which met regularly and conducts weekly inspection with all relevant parties, including airlines. – Bernama
