Tall structures

Dominion E&C is a leader in the design, construction, and maintenance of reinforced concrete storage structures including silos, stacking tubes, and other special structures for the storage of bulk materials.

Silo Design & Construction

New construction

There are many factors to consider when designing a silo including the materials to be stored and equipment and material handling requirements.

The design of the silo walls are generally very straight forward but the internal cones and floors require considerable engineering expertise and experience. Current technology often requires inverted concrete cones and we have developed a precast system with external concrete stitching to achieve a finished cone in the minimum time period. Steel cones require particular experience to achieve an economic design which would give consideration to fabrication and installation.

Materials Stored:

  • <
  • Cement
  • Gypsum
  • Fly Ash
  • Grains/Feeds/Meals
  • Limestone
  • Waste Water
  • Liquefied Natural Gas (LNG)
  • Wood Waste

Industries Served:

  • Power
  • Agricultural
  • Cement
  • Biomass
  • Waste Water
  • Mining/Materials

Materials & Methods of Construction:

  • Traditional Reinforcing
  • Reinforced Concrete with Post-Tensioning
  • Jumpform & Slipform Construction
  • Stand Alone Silos
  • Ganged Silos

Advantages of Reinforced Concrete:

  • Increased longevity and durability
  • Environmental protection of stored product
  • Impact resistant
  • Resistant to catastrophic failures
  • Eliminates the need for large (and expensive) cranes for erection
  • Better protection of mechanical and electrical equipment
  • Ability to strengthen later for new applications using post-tensioning
  • No height or diameter limitations
  • Eliminates initial and frequent painting costs

Silo Inspections, Repairs & Modifications

Avoid failure or collapse with regular inspections

Regular inspection of your silo plays an important role in identifying potential maintenance and repair issues, and are key to performing repairs in a cost effective and timely manner. Inspections are critical to the equipment as well as the safety of your plant personnel, as neglect may lead to severe deterioration and potential failure or collapse.

Our experienced team of engineers and skilled construction experts have developed detailed inspection and maintenance programs for all types of structures including silos. We’re able to evaluate the current condition of the structure to determine if the life of the silo can be extended, modified and utilized for another purpose, or if it needs to be demolished.

LNG tanks

LNG tank construction

Over the past few decades, world consumption of LNG has increased more than five-fold and it is predicted that this growth will continue to be very strong. The growing demand from large markets combined with the increasing popularity in a number of other smaller markets has resulted in the development of many new LNG facilities throughout the world.

There is currently much activity underway in the LNG supply chain in preparation for current and predicted demands. To support this market Dominion can provide comprehensive build services for full containment LNG storage tanks. We can deliver projects on a lump-sum basis using in house resources to provide project planning and management, procurement, fabrication, construction, commissioning and operator training.

Global Presence

With offices worldwide, we have the resources to build LNG storage tanks in any location and under all types of logistical constraints. Dominion’s integrated resources and global presence translate into low-risk, high-value LNG construction solutions for our customers.
