Engineered Bacteria Can Fill Cracks In Aging Concrete

Researchers at the University of Newcastle in the UK have created a new kind of concrete glue that can patch up the cracks in concrete structures, restoring buildings that have been damaged by seismic events or deteriorated over time. But the glue isn’t an adhesive or some kind of synthetic material; the researchers have custom-designed a bacteria to burrow deep into the cracks in concrete where they produce a mix of calcium carbonate and a special bacteria glue that hardens to the same strength of the surrounding concreate.
