Project Description

Ground improvement under the second runway of Changi airport

For the construction on the second runway of Changi airport, 7 m of hydraulic fill were placed over varying layers of both old and recent marine clays. Settlement of these clays could amount to several metres over a ten year period. The combination of dynamic compaction and vertical drains up to a depth of 43 m (a first at the time) convinced the local authorities (PSA – port of Singapore Authority) of the effectiveness of Menard techniques.


The Menard group develops foundation solutions based on ground improvement and reinforcement technologies. Its treatments eliminate the need for the deep foundations traditionally used to support surface structures.
