Flexus, a "bendable" concrete that can be sprayed onto building walls, will be used to reinforce some older buildings in Christchurch, New Zealand, to make them more earthquake resistant. The engineered concrete uses polyvinyl alcohol synthetic fibers mixed with concrete to provide tensile strength. "If we spray this material onto them, we can turn [them] into something that can bend and take the earthquake loads and keep the building together," said Derek Lawley of Reid Construction Systems.
