The promoter of the project is Opal. It consists of three circular tanks which will be used for storage of ethylene. Each tank of 47 ID with varying thickness of 1.20 m to 0.60 m through the total height of 20 m.
“PERI formwork system is one of the best formwork system for construction of circular tank. In this system the result of providing filler is very good for shape, finishing of the concrete and alignment of two shutter, as per my practical experience.”
