Post-Tensioning & Concrete Application

In the low-profile model, a high-strength post-tension is often used to allow the dome profile to be more shallow, resulting in a more aesthetically appealing project.

Strength to support loads from inside and out

Our concrete domes are constructed using an air-inflated membrane and the shotcrete method to place the concrete: Multiple applications of concrete and reinforcing steel rebar are applied until the necessary design thickness is achieved and the dome is superior in its strength.

When completed, the dome is capable of bearing greater loads and withstanding more extreme weather than any other structure of similar size and cost.

Strongest structure in the world

With each project carefully completed to engineer specifications, the result is a precise dome, nature’s perfectly strong shape. The dome’s double curvature requires no interior supports or beams to obstruct views or clog open spaces; it also provides excellent strength from every direction—important for a dome that might support balconies, mezzanines, walkways, press boxes, scoreboards, and AV equipment.

Built to last

Protected from water and extreme temperature fluctuations, the concrete structure has the potential to last centuries. Maintenance is virtually nonexistent too.

Domes function well as strong safety shelters. Even if a building isn’t destined to become a community storm shelter, customers can feel a greater sense of confidence knowing their structure is supremely secure.

In the United States, Dome Technology constructs many FEMA-rated emergency shelters, which must meet stringent requirements including the ability to withstand projectiles and their impact force. A dome can resist high impact loads without requiring interior beams, thanks largely to our construction process.
