Bangkok shooting: Gunman who killed 5 people ‘had grudge’; Thai army accuses Cambodia of breaking truce: Singapore live news
The sinkhole at Tanjong Katong Road South has been filled and testing is ongoing to prepare the stretch of road for use. Herman Ching, director of national water agency PUB’s water reclamation (network) department, told reporters late on Monday (28 July) that the sinkhole was refilled early in the day with liquefied stabilised soil, which is made of soil, cement and water.
When poured into the sinkhole, it will fill all the voids in a matter of hours and eventually form a “competent soil-like material”. “This material will provide the strength needed for road construction later,” he reportedly said.
On PUB’s Facebook page, it said that it’s “conducting rigorous tests and scans to detect underground cavities and verify ground stability”. It added that “the tests are:
1. ground-penetrating radar (GPR) scan, which uses radio waves to assess the subsurface layers;
2. probing, which involves drilling into the ground to detect the ground condition and presence of any voids; and
3. seismic scanning to record sound waves underground, to identify anomalies that might indicate voids.”
Meanwhile, the Building and Construction Authority (BCA) will carry out an independent investigation into the sinkhole that formed in Tanjong Katong Road South, said National Development Minister Chee Hong Tat.
