Sealing the future: Sustainable waterproofing for net-zero infrastructure

This article examines how environmentally friendly waterproofing is paving the way for the country's infrastructure to have a long, sustainable future.

Mumbai's towering skyscrapers and extensive metro lines are put to the test when the monsoon unleashes 800 mm of rain in a single month. Waterproofing is now recognised as the foundation of long-lasting structures as India's construction sector soars toward a $1 trillion valuation by the end of 2025. The country is building an infrastructure network that must not only endure the wrath of nature but also support its ambitious net-zero goals, with 50,000 kilometres of highways currently under construction and 11.5 million new homes being built every year. Once an afterthought, waterproofing is now a vital barrier that ensures structures like buildings and bridges remain sturdy while reducing energy waste and environmental impact.

The goal is to create a future in which India's urban landscape, which will house 40 percent of the country's population by 2030, coexists peacefully with the environment rather than just fixing leaks. Waterproofing solutions must address a range of climates while promoting sustainability objectives, from the humid beaches of Chennai to the arid regions of Rajasthan. With the government investing $1.4 trillion in infrastructure by 2030, India is redefining construction through the use of cutting-edge materials, intelligent technologies, and cooperative approaches.
