Seismic Restraint System

Seismic Restrain System for Water & Oil Storage Tanks (PS1 Certified)

The Seismic Restrain System is engineered to provide structural stability and compliance for aboveground water and oil storage tanks ranging from 300L to 1500L capacity. The system has been PS1 certified by a Chartered Professional Engineer confirming it meets the relevant seismic design and installation standards.

300L, 600L - Complete System with 2 premium tie downs
500L, 1000L, 1500L - Complete System with 3 premium tie downs

• Certification: PS1 Engineer approved for seismic restraint.
• Anchorage: Ground-anchored system designed to safely transfer seismic forces from the tank to the foundation.
• Components: Supplied with 3 engineered, high-tensile tie downs, tested for seismic load performance
• Material Quality: Constructed from premium-grade, corrosion-resistant materials for long term durability.
• Application Range: Suitable for water tanks and oil tanks within the 300l - 1500L capacity range.
• Design Intent: Prevents displacement, overturning or uplift of tanks during seismic activity.

The Seismic Restraint System has been designed and review in accordance with the following New Zealand standards and building code requirements.

• NZS 1170.5:2004 - Structural design actions: Earthquake actions.
• NZS 3101:2006 - Concrete structures standard (relevant to anchoring foundations).
• NZS 3404:1997 - Steel structures standard (relevant to restraint hardware).
• NZ Building Code Clause B1 - Structure: Performance requirements for stability and load resistance.
• NZ Building Code Clause B3 - Durability: Materials selected for long term performance and resistance to corrosion.
