Application of Jet Grouting for the Construction of Sydney International Airport Runway End Safety Area

Menard - Bentonite Slurry Wall

As part of the upgrade programme of Sydney Airport, the end of Runway 07/25 is being extended for aircraft emergency overrun to achieve compliance with new international safety requirements. The new Runway End Safety Area (RESA) project is being built in a location that collides with the heritage listed Southern and Western Suburbs Ocean Outfall Sewer (SWSOOS), a diverted airport perimeter road and the existing M5 Motorway Tunnel (see Figure 1). As the project location is at the edge of the Cooks River, relocation space is very limited, and it has been understood that the most suitable option for resolving the problem is to construct a 90×90 m2 concrete area that is bridged over the mentioned facilities.
