GRP Water Tank Reinforcement – AQUOSYS Limited
Internal Reinforcement System
At AQUOSYS, our GRP water tanks are engineered not only for durability and hygienic water storage but also for structural integrity under diverse environmental conditions across East Africa. Our advanced internal and external reinforcement systems are designed to meet international quality benchmarks while ensuring safe, long-lasting performance in urban, industrial, and remote settings.
The internal reinforcement system is essential in ensuring that the GRP tank maintains its shape, strength, and water-tight seal, even under high-volume or pressurized conditions. AQUOSYS uses high-grade, corrosion-resistant materials to ensure long-term performance and safety.
Key Features:
Stainless Stay Rods (SUS 304/SUS 316):
These rods internally brace the GRP panels, distributing water pressure evenly and preventing panel deformation.Chlorine-Resistant Roof Bolts:
To withstand exposure to chlorine gas inside potable water tanks, stainless steel bolts or PVC-capped bolts are used, especially for roof panel assemblies.Fast & Modular Installation:
Our optimized design ensures quick assembly, precise alignment, and minimal on-site adjustments—ideal for both small-scale and large-scale deployments.
External Reinforcement System
For tanks up to 3 meters in height, AQUOSYS offers a non-internal reinforcement design, eliminating internal bracing components to:
Enhance water cleanliness
Facilitate easier cleaning and maintenance
Avoid potential rusting in high-chlorine environments
For tanks above 3.5 meters, optimized internal bracing is introduced to maintain structural stability under high hydrostatic pressure, while still prioritizing accessibility and hygiene.
