About us

Built on Trust. Proven by Results.

For over five years, Sanju Waterproofing has been helping homeowners and businesses across Mauritius protect their properties from costly water damage. Founded in 2019 in Port Louis, the company was created with one clear mission: to provide specialist waterproofing solutions backed by real expertise, quality workmanship, and long-term reliability.

Before Sanju Waterproofing, many property owners relied on general contractors for waterproofing work, often resulting in recurring leaks and expensive repairs. We changed that by focusing exclusively on waterproofing systems engineered for Mauritian conditions.

Today, Sanju Waterproofing Ltd is recognised as one of Mauritius’s leading waterproofing specialists, trusted for residential villas, commercial buildings, hotels, swimming pools, industrial facilities, and complex leak remediation projects.

We understand the challenges of the Mauritian climate — cyclone seasons, heavy monsoon rains, intense UV exposure, and salt-laden coastal air. Every waterproofing system we install is carefully selected and applied to withstand these demanding conditions and provide lasting protection.
