These are shallow brick domes that are used as a conventional roofing technique in villages in Rohtak. They are almost flat- so flat that the curve is hardly noticeable. Another attractive feature of this construction technique is that it uses no shuttering and is hence simple and highly economical albeit depending heavily on knowledge, intuition and skill.
Ordinary bricks are used. A rich cement mortar of 1:2.5 or 1:3 is used and the bricks are used dry to ensure better initial adhesion (considering that there is no shuttering used).

Ring beams are nominal in size (roughly 250-300mm deep for a span of 12-15ft).
Unfortunately this technique has not been explored scientifically and has no prescribed codes and regulations because of which its capacity and efficiency are not known.
However, given its advantages, these Rohtak domes have great potential only for want of exploration.
