#1, scientists specialise the bacteria on a certain 'nutrition' so it doesn't attack material and so forth weakens the construction, the 'cancer' stops when there's nothing left of its favourites...

What if there is a substance that makes the bacteria run wild... and my neighbor gets it's hands on it

This really is genius but i have to agree with #1, until I see some long term tests im gonna be skeptical about using this so I i dont get house cancer

The bacteria used is sealed in pellets along with its "food" and mixed into the concrete mix.Only when tiny cracks form in the concrete – breaking open the pellets – and water seeps inside will the bacteria activate and begin to consume the food that has also been freed. As they feed, they combine the calcium with oxygen and carbon dioxide to form calcite – essentially pure limestone. It is more of a water sealant than a structual repair since limestone is not as hard as concrete,but it keeps water from entering surface cracks and damaging steel reinforcement in the structure. It also prevents water from entering cracks and then freezing in cold weather which causes much damage and spalling of the concrete.

Great invention, no doubt there
but his speech about filling up cracks reminded me of this video:

I hope this concrete works better than the stuff they used in my new home. It was supposed to 'repair' itself when cracks or leaks developed......does not work.
