BMC uses geo-polymer for South Bombay's old drain maintenance

The BMC has undertaken major maintenance work of century-old storm water arch drains in south Mumbai at an estimated cost of Rs 4.16 billion. Geo-polymer technology is being used for the first time to avoid digging and trenching of the road surface.

The underground arch-drains were constructed during the British era. Now old and dilapidated, they face risk of collapsing and hence road cave-ins. In 2022, the civic body conducted a survey to assess their structural condition, after which it was decided to use a geo-polymer coating on their walls. The geo-polymer lining (GL) technology applies a chemical-based lining on the corroded walls to prevent water leak and any damage to roads.

"As these drains are either arch-shaped or horse-shoe shaped, the coating will be applied on the inner walls. The polymer coating will also make their surface smooth and ensure uninterrupted flow of water. The work is expected to be completed in the next three years," said a civic official.
