Expert Waterproofing for Tropical Conditions. Keeping Mauritius Dry Since 2019
Our Services
Trusted Across Mauritius & Rodrigues
Since our founding, we have successfully completed over 500 waterproofing projects across residential, commercial, hospitality, and industrial sectors.
Roof Waterproofing
Your roof is the first line of defense against Mauritius’s intense sun, heavy rainfall, strong winds, and cyclone conditions. At Sanju Waterproofing, we provide professional roof waterproofing solutions for concrete roofs, flat roofs, terraces, metal roofs, and commercial roofing systems. Our team carefully prepares every surface before applying high-performance waterproof membranes and protective coatings designed specifically for tropical island environments. The result is long-lasting protection against leaks, cracks, standing water, and structural deterioration, helping extend the life of your property while reducing future maintenance costs.
Basement & Foundation Waterproofing
Water intrusion below ground level can lead to serious structural damage, dampness, mould growth, and weakened foundations. Our basement and foundation waterproofing systems are designed to prevent moisture penetration and protect your building from long-term water-related issues. We use specialised waterproof membranes, drainage systems, cementitious coatings, and injection techniques to create a reliable moisture barrier around below-ground structures. Whether for residential homes, commercial buildings, or industrial facilities, we deliver solutions that provide lasting structural protection and peace of mind.
Wet Area Waterproofing
Bathrooms, kitchens, balconies, laundry rooms, and other wet areas are highly vulnerable to hidden leaks and moisture damage if not waterproofed correctly. Our wet area waterproofing services create a durable protective barrier beneath tiles and finishes to prevent water seepage into walls, floors, and surrounding structures. We use high-quality waterproofing systems that resist humidity, standing water, and daily wear while helping prevent mould growth, peeling paint, tile damage, and structural weakening. Every application is completed with precision to ensure long-term performance and reliability.
Leak Detection Services
Hidden water leaks can cause significant structural damage and costly repairs when left undetected. Our professional leak detection services help identify the exact source of water intrusion quickly and accurately without unnecessary demolition or disruption. Using systematic inspection methods and specialist equipment, we locate leaks in roofs, terraces, basements, wet areas, plumbing systems, and concrete structures. Once identified, our team provides practical repair recommendations to prevent further damage and restore the integrity of your property efficiently and cost-effectively.
Cold Waterproofing
Cold waterproofing focuses on areas that are constantly exposed to water, humidity, and moisture. At Sanju Waterproofing, we use high-performance waterproof membranes, cementitious coatings, and liquid-applied systems to create a strong protective barrier against water penetration. Our solutions are ideal for bathrooms, terraces, balconies, swimming pools, kitchens, and other cold environments where long-term moisture resistance is essential. Every project is carefully prepared and professionally applied to ensure reliable performance, prevent hidden leaks, and extend the lifespan of your property.
Hot Waterproofing
Hot waterproofing is designed to safeguard roofs, walls, foundations, basements, and exterior surfaces from water intrusion caused by rainfall, humidity, and changing weather conditions. At Sanju Waterproofing, we apply advanced protective systems that help prevent cracks, dampness, seepage, and long-term structural damage. Using specialist coatings, membranes, and sealing technologies, we create durable waterproof barriers tailored to Mauritius’s tropical climate. Our hot waterproofing solutions improve structural protection, reduce maintenance costs, and provide lasting peace of mind for residential, commercial, and industrial properties.
