Custom Water Storage Solutions for Every Project
From 10,000L to 2M+L — engineered for reliability.
Types of Rainforcement
Providing long-lasting, corrosion-resistant GRP tanks for residential, commercial, and industrial applications.
Internal Tie Rod Reinforcement
Internal tie rod reinforcement is used inside GRP sectional tanks to counteract water pressure and keep the panels stable. This method is ideal where space is limited, as the reinforcement is contained within the tank itself, offering a clean design while ensuring long-term durability and preventing panel deformation.
External Tie Rod Reinforcement
External tie rod reinforcement uses steel bracing around the outside of the GRP tank to provide strength and stability. It is especially effective for large-capacity tanks, as the external system is easy to install, inspect, and maintain, making it a reliable and cost-effective choice for industrial and municipal projects.
