FANTASTIC FACT!

Self Healing Concrete uses a strain of mineral-eating bacterium that can tolerate high alkaline environments such as those found in concrete. Millions of dormant bacteria are incorporated in the aggregate during concrete production along with packets of chemical "feed". If the concrete is cracked and oxygen and water are introduced, the bacteria become activated. The bacteria then convert the feed into calcite, which seals the crack. Once plugged the bacteria return to their dormant state.
