Large Scale Dissemination of Stabilised Mud Block Technology for Rehabilitation after Bhuj Earthquake: Some Lessons

Abstract

Large scale devastation of buildings occurred in the state of Gujarat in India during the earthquake of 2001. Massive rehabilitation programmes were undertaken by the government agencies and NGO's. This paper is focused on the housing rehabilitation programme using stabilised mud blocks undertaken by HunnarShaala; an NGO which was a part of Abhiyan at that time of the earthquake. Nearly 4000 SMB houses were constructed spreading across the Gujarat state. The size of the houses ranged between 45m² to 60m² in plinth area. This paper discusses the following aspects of stabilized mud block (SMB) technology dissemination.

• Preparedness and mechanisms required to adapt and transfer the SMB technology to implementing agencies.
• Devising mechanisms for larger scale dissemination of SMB technology using manual machines in a decentralized manner
• Experiences and challenges faced during large scale dissemination of technology
• Lessons learnt to market the SMB technology successfully

The paper also discusses the details of traditional house plans adopted to use SMB technology and the people’s reactions in adopting to new construction techniques. Technical aspects of SMB technology including types of soil, soil modifications and strength characteristics of blocks have also been discussed.
