A slab of self-healing concrete bends under 5 percent tensile strain, the force needed to stretch a material by 5 percent of its initial size.

While ordinary concrete would crumble under such pressure, the new material forms micro-cracks that can then auto-seal after being exposed to water and carbon dioxide, researchers said in March 2009.

Actually the sidewalk in front of my house is warped. We've had the county come out to fix it before - basically once the weather gets hot, the concrete swells up and it cracks. But once the weather cools down at night, it flattens out. So basically there's nothing they can do - it's just the way the earth is there.

So I guess the flexible version would work in this case.
