What You Need to Know About a Terrace for Your Dome
You can install a dome on your existing terrace or build a new one. But what are the key differences?
VikingDome domes are engineered to withstand snow and wind loads. However, the terrace must be securely anchored to the ground to prevent the dome from being lifted or displaced by strong winds. The larger and lighter the dome, the more susceptible it is to wind uplift, which can damage property and pose safety risks.
If You Already Have a Terrace
Make sure your terrace is firmly attached to the ground. Are the foundations solid enough to support the dome in extreme weather conditions?
If You’re Building a New Terrace
The classic method involves installing permanent foundations, joists, and wooden decking. However, in some cases, a temporary or non-invasive terrace is required—especially in locations where foundations are not allowed.
In such cases, a ballasted terrace is used. This is a heavy platform that rests on the ground by its own weight, without anchoring.
Ballasted terraces are ideal for:
- Short-term events where the terrace will be dismantled afterward
- Protected areas where concrete foundations or ground screws are prohibited
- Rooftop installations where drilling anchors could damage waterproofing
Keeping the Dome Interior Dry
Rain and melting snow flow down the dome’s surface and onto the outdoor terrace. This moisture can soak the wood both outside and inside the dome. To prevent this, the interior flooring must be elevated or separated from the outdoor decking.
If the dome is installed on a larger existing terrace, we recommend adding an elevated floor inside the dome. This ensures the interior remains dry even during heavy rain.
If you’re building a new terrace specifically for the dome, we suggest creating a circular terrace that fits inside the dome’s footprint. The dome’s facade material should direct water runoff below the level of the interior floor.
If you want an outdoor terrace around the dome, make sure its surface is clearly separated from the interior flooring.
