Millions of pounds are invested in maintaining, fixing and restoring roads, buildings, tunnels and bridges annually. This is because all concrete eventually cracks and needs to be restored. Self healing concrete would add years to a building’s life and be an enormous help time-wise and financially. The science behind this technological marvel shows itself when water enters a crack. This reactivates the bacteria that was mixed in during the mixing process. When the bacteria is activated, it excretes calcite which then heals the crack.
