High-Tech Ground Assessment Underway After Successful Cavity Fill
In a demonstration of Singapore's sophisticated infrastructure management capabilities, national water agency PUB has initiated comprehensive ground stability testing at the Tanjong Katong Road South sinkhole site, following the successful filling operation completed Monday.
Innovative Engineering Solutions
The agency employed an advanced engineering solution using liquefied stabilised soil - a cutting-edge mixture of soil, water, and cement specifically designed for void filling applications. This technical approach exemplifies Singapore's commitment to efficient urban management.
'The liquefied stabilised soil flows into and fills the cavity, forming a competent soil-like material in hours,' explained Mr Herman Ching, PUB water reclamation department director, highlighting the sophistication of the chosen method.
Multi-layered Testing Protocol
PUB has implemented a comprehensive three-tier testing strategy to ensure public safety:
- Ground-penetrating radar scanning - Utilizing radio wave technology to detect subsurface anomalies
- Deep ground probing - Conducting 20-meter depth tests to assess ground condition
- Continuous monitoring - Maintaining vigilant oversight of the affected area
Technology-Driven Infrastructure Management
This incident showcases Singapore's world-class infrastructure maintenance protocols, demonstrating how the nation continues to lead in urban engineering solutions across Asia. The transparent approach, including media access to the worksite, reflects the country's commitment to public accountability and technical excellence.
