Mr Herman Ching, director of national water agency PUB's water reclamation (network) department, told reporters late on July 28 that the sinkhole was refilled early in the day with liquefied stabilised soil, made of soil, cement and water.

When poured into the sinkhole, it will fill all the voids in a matter of hours and form a "competent soillike material".

"This material will provide the strength needed for road construction later," said Mr Ching.

Shortly after the sinkhole was filled, work started to test the ground using three methods.
