Skilful engineering could shield KL against sinkholes S, say experts

While Kuala Lumpur is a safe place to live in, construction in limestone areas should be designed through proper engineering to prevent sinkholes, said former Malaysian Geotechnical Society (MGS) president Lee Peir Tien.

"Construction in limestone areas can lead to sinkholes if not properly designed and treated," he said.

Mr Lee explained that natural sinkholes typically occur in areas with limestone formations.

"Limestone is a naturally soluble rock, which means it can dissolve over time, leading to the formation of cavities or empty spaces underground.

"These cavities are an inherent issue in limestone regions. When the roof of a cavity collapses, it can cause a sinkhole to form at the ground surface." For construction in limestone areas, Mr Lee said detecting and treating cavities is a common practice before starting any construction work. "This helps prevent sinkholes from forming during or after the construction process," he said, when contacted.

Mr Lee said that man-made sinkholes can be prevented through proper engineering measures.
