New Delhi: An IIT-Delhi audit of Godrej Summit, a housing project Dwarka Expresswayhas warned about the presence of chlorides in the water in the region which has a detrimental effect on concrete buildings and suggested a robust maintenance framework to tackle the problem.
The report of the IIT panel on the summit in Sector 104 states that chloride in water corrodes the embedded steel reinforcement of buildings, affecting their strength. The audit was commissioned by Godrej Properties.
“Based on our understanding of the many projects in this area of Dwarka and Dwarka ExpresswayIn its report, the IIT team said, “We have seen similar issues being faced by many other communities.
Excess chloride was also found in concrete in four towers in Chintels Paradiso, where two residents died in February 2022 in a vertical cave-in in five flats. Since then, that tower, ‘D’, has been abandoned and three others have been declared unfit for habitation. Paradiso is in the same area, Sector 109, and is also undergoing a structural audit by IIT-Delhi.
After the completion of the summit in 2017, problems such as sagging balconies and floors began to emerge in some apartments. A spokesperson for the company said, “We deeply regret the build quality issues.” The company said it has taken initiatives to strengthen and enhance the balconies throughout the project and has decided to initiate an audit.
The report, authored by Professor Bishwajit Bhattacharjee, states, “The base investigation found that the structural integrity and safety of the basement and overall structure elements are apparently intact and subject to proper repair of isolated hazards.”
It added that technical tests had revealed the presence of chlorides in the concrete, which could be due to chlorides in the water or those used in the concrete. “This chloride, when exposed to water, initiates corrosion of the embedded steel reinforcement,” the report said.
The IIT team noted that corrosion can be prevented by preventing water from entering concrete and advised a “robust and thorough maintenance framework for concrete, waterproofing, painting and mechanical, electrical and plumbing (MEP) services”.
