Sinking Skyscrapers Can Be Prevented Using This Construction Method | WSJ

Super-tall skyscrapers are being built in cities around the world where they may normally sink, and builders are using a unique engineering method called deep-soil mixing to make it happen. Mixing soil and cement creates a super-strong slurry called “soilcrete” that is three times stronger than regular soil.

WSJ explains the process of essentially changing the earth, and the risks it poses as cities expand.
