Member of Parliament for Marine Parade-Braddell Heights GRC Goh Pei Ming told reporters during a second visit to the site on Sunday that works are “progressing on track well”.
Goh also said that backfilling works are ongoing to fill any cavities around the walls of the sinkhole with “a kind of soil stabiliser”.
AsiaOne observed that a truck-mounted concrete pump has been deployed since operations transited to the backfilling phase. A consistent stream of cement mixers were also seen at the work area, working in tandem with the truck.
PUB, the lead agency coordinating repair works, said in a statement on Sunday night that the sinkhole has been filled with liquefied stabilised soil (LSS) to further stabilise the area.
Goh added that graded stones, commonly used for road bases, will then be added before the road is repaved.
Checks and scans will then be carried out on both sides of Tanjong Katong Road South to ensure that no other cavity remains.
A timeline for the reopening of Tanjong Katong Road South will only be announced after the scans are completed.

“Given what has happened, the staff are going to be additionally sure, to ensure that the road will be safe before we clear the road for reopening,” said Goh.
On Sunday morning, the Land Transport Authority said that Tanjong Katong Road South - between Mountbatten Road and East Coast Parkway (ECP) - will remain closed until further notice for repairs.
Bus services 36 and 48 have been diverted.
