Water Tank Waterproofing in Dubai & Across the UAE
Water tank waterproofing is critical for preventing leaks, mold buildup, and contamination. Whether your tank is overhead, underground, or GRP, we apply certified GRP lining, epoxy coatings, cementitious materials, and crack injection systems to stop water loss and protect stored supply.
At Salman Syed Technical Services, our work is trusted by property managers, engineers, and maintenance teams across the UAE.
Why Waterproofing the Water Tank Is Essential in the UAE
In UAE’s hot, humid conditions, water tanks are exposed to high stress, causing cracks, coating failure, algae buildup, and water seepage. Without proper waterproofing, this can lead to bacterial contamination, utility losses, and structural damage. Our waterproofing method for water tanks ensures hygienic storage, long-term sealing, and compliance with building safety.
If you’re facing leakage or moisture issues near water tanks installed in basements, we recommend checking our basement waterproofing services as well.
Waterproofing Methods for Water Tanks
We tailor the method based on tank type, condition, and usage:
GRP Lining System
Seamless fiberglass lamination, ideal for long-term protection in concrete and GRP tanks.
Cementitious Coating
Flexible two-component slurry, perfect for underground concrete tanks and internal walls.
Injection Crack Repair
High-pressure PU injection stops active water leaks through structural cracks.
Epoxy Coating
Hard-wearing and non-toxic, used for smooth finishes in steel and GRP tanks.
