Hangar Resupported at RAAF Base Williamtown

RAAF Hangar Pavement Problem

Pavement in the hangar areas where the jet fighters stand at the RAAF base, at Williamtown, NSW, Australia, had developed a significant problem.

The problem emanated from leaking stormwater pipes sucking in fine materials and thus causing voids and loss of proper support for the slabs.

Pipelines under the hangar pavement required re-lining first

Prior to Uretek filling voids and compacting the ground directly under the slabs, the pipes were first relined to prevent a recurrence of the problem.

Hangar Pavement Voids Filled & Sub-base Ground Strengthened

Then the Uretek Slab Lifting technique was used to fill voids immediately under the slabs.

Uretek Deep Injection was employed to compact the sub-base along the 320 m of pipeline, as shown in the diagram.
