Case Studies

Mumbai’s stormwater drainage system, much of it constructed during the British colonial period more than 100 years ago, has reached a critical stage of deterioration. Structural failures, cracks, displaced brickwork, mortar loss, and localised collapses have increasingly compromised flood resilience in one of the world’s most densely populated coastal cities. To address this growing risk, the Brihanmumbai Municipal Corporation (BMC) launched India’s first large-scale trenchless geopolymer lining initiative, targeting 27 critical arch drains spanning more than 14km as phase one of a major rehabilitation project.

Mill Creek Residential Trust selected a LOCTITE GeoSpray geopolymer spray‑applied pipe lining (SAPL) solution to rehabilitate a 72-inch diameter brick storm drain in Nashville, Tennessee.
