‘Self-healing’ concrete is being developed. Researchers are using a ground-borne bacteria – bacilli megaterium - to create calcite, a crystalline form of natural calcium carbonate. This can then be used to block the concrete’s pores, keeping out water and other damaging substances to prolong the life of the concrete.
