Silo exclusions

  • Silo concrete foundation *We strongly advise all customers to consult a structural engineer concerning their foundations. Since foundations are not covered by warranty, getting this aspect correct is crucial. Typically, sites will require excavation, followed by the application of road base and crusher dust to minimise movement after construction. If we determine that the foundations are inadequate, we will not move forward with the job.

Sealed, gas-tight silos

Sealed silos, otherwise known as gas-tight silos, are recommended for long-term storage of grain.

Sealed silos are a controlled atmosphere that acts as fumigation chambers for effective control of insects at all life stages. A silo is only truly sealed if it passes a five-minute half-life pressure test according to the Australian Standard AS2628. A silo that does not meet the standard will allow gas to leak out. The concentration of fumigant will be reduced, and there is a chance of insect survival.

National Grain Solutions ensures it has met and exceeded Australian Standard AS 2628 of sealed silos. This is done throughout the manufacturing process by:

  • Ensuring all seams and joins are sealed both inside and out
  • Rubber Seals made of high density on all openings
  • Pressure relief oil valve
  • Ability to pressure test your silo on site
  • Silos are pressure tested before leaving our factory
