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.
Crack Injection & Leak Repairs
Structural cracks and active leaks can quickly worsen if left untreated, causing serious damage to walls, foundations, ceilings, and underground structures. Our crack injection and leak repair services use advanced polyurethane and epoxy injection systems to seal cracks from within and stop water intrusion at its source. We specialise in repairing active leaks in basements, retaining walls, roofs, water tanks, and concrete structures using methods that restore strength and waterproof integrity. Our experienced specialists carefully assess each issue to deliver the most effective and long-lasting repair solution.
Swimming Pool Waterproofing
Swimming pools require specialist waterproofing systems capable of withstanding constant water pressure, chemical exposure, and changing temperatures. At Sanju Waterproofing, we provide professional swimming pool waterproofing solutions for residential, hotel, and commercial pools throughout Mauritius. Our systems help prevent water leakage, surface deterioration, and structural damage while maintaining the durability and efficiency of your pool. From new pool construction to repair and rehabilitation projects, we apply reliable waterproofing methods designed for long-term performance in demanding environments.
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.
