In the article, “The Self-Healing Concrete That Can Fix Its Own Cracks,” Spinks (2015) stated that Hendrik Jonkers’ innovation is to “decrease the amount of new concrete produced, lower maintenance and repair costs for city officials, building owners and homeowners” by inlaying self-activating limestone-producing bacteria into concrete.  The self-healing concrete has longevity of up to 200 years and helps to reduce carbon emitters. However, it can only repair up to 0.8mm wide of cracks and cost   €30  more than normal concrete. Regarding this, Alker believes that it will be hard to convince the industry to adopt the new innovation. It will take unconventional consumers and developers who are willing to test their building with the new concrete to demonstrate positive results before others will tag along. Jonker has been experimenting across the world where he claims that the people realized the profit because they can save up on the maintenance.
