How to Build a Concrete Dome Shell

A Simple Method Using Basalt Fibre Reinforcing

A Dome Building Manual

A step-by-step dome building manual of Domeshells method of building dome structures suitable for DIY, trades and professional builders. Anyone can learn.

The basalt-reinforced concrete dome building manual


The method we teach here is a simple way to fabricate the shape of a dome using basalt fibre rebar.

We use mesh, sand and cement to build extremely strong thin concrete shell structures.

We include plans and specifications of a design capable of high cyclonic winds.

It is a method that does not require a mold.

It is cost-effective and easy to learn, making it suitable for DIY, trades, and professional builders.

Benefits of The No-Mold Method

  • Easy to get materials
  • Easy to learn and apply
  • It works great to build as a team
  • Learn to make your own dome shelter or home

Frequently Asked Questions

1. What is the Domeshells “Simple Method” of building dome structures?

The Domeshells simple method involves 3 basic stages. Firstly the foundation and slab, then we fabricate a wire frame structure using basalt rebar grid of vertical and horizontal bars – like a birdcage. Over the bird cage we tie a fine basalt mesh. Next we apply layers of render or plaster to build up the desired wall thickness.

2. What is basalt fibre reinforced concrete?

Basalt fibre reinforced concrete is a type of concrete that is reinforced with basalt fibres, which provide additional strength and durability.

3. How long does it take to build a dome structure using the Simple Method?

The time it takes to build a dome structure using the Simple Method will depend on the size of the structure and the level of experience of the builder and team. At our training workshops it generally takes around 7-8 students, 7 days to construct a 3.0m diameter dome from the slab up.

4. Can I build a dome structure on my own?

Yes, the Simple Method is easy to learn and can be done by anyone. However, it is recommended to have at least one other person to assist with the construction.

5. Is the Simple Method suitable for commercial buildings?

Yes, the Simple Method can be used to construct commercial buildings such as offices, schools, and community centers.

6. How does the Simple Method compare to traditional building methods?

The Simple Method is designed for simplicity without the use of complicated equipment or technology. It is labor intensive. It forms the basis of our more advanced methods such as using an air form as a mold and also using rigid fiber glass mold that are the most efficient. Our most sophisticated system is generally quicker than traditional building methods. It also requires less trades and skilled labor.

7. What are the maintenance requirements for a dome structure built using the Simple Method?

A Domeshell structure requires minimal maintenance after it has been water proof coated and painted. There is no steel that can rust and the shell is extremely tough. However, it is recommended to inspect the structure regularly and make any necessary repairs.
