EarthQuake Mitigation by Used Tires.wmv

Used tires can be built into house foundations to work as low cost base isolators during earth quakes.

They don't have much value, not even in the informal sector. Usually dumped in the open, they create mosquito breeding conditions with subsequent malaria and dengue risks.

Another synergy effect can be achieved: A concentration of waste tires in open air dumps constitutes a serious fire hazard; once ignited rubber fires are extremely difficult to fight.

Once built into the foundations, away from the ultraviolet radiation of the sun, tire rubber does not lose compression strength anymore. There is neither any environmental danger as recycle industry research in Sweden has confirmed.

The "Elephant foot on tire" concept is based on low cost construction principles. In the bottom of the foundation ditches round river stones are placed to work as roller bearings. The tires slide on top in an earth quake and help also to absorb the vertical ground movements. Prefabricated concrete "elephant feet" connect between the tires and the regular foundation beams. The volume of reinforced concrete for these components is limited compared to the total construction quantities. Savings should be possible to make on conventional foundation construction such that the added costs for these shock absorbers should be minimal if any.

The handling of the tires and manufacturing of components will in addition create livelihood opportunities.
