Salient Technical Features

Corrosion of reinforcement was found to be the major cause of failure of RCC structure in coastal area. A pyramicial roof with brick and cement concrete without reinforcement was therefore developed. The roof is provided with peripheral RCC ring beam. The beam is supported on brick columns of walls and is cast as integral part of the pyramidal roof using suitable shuttering.


Most suitable for low cost houses in cyclone affected and other coastal areas
