Concrete Cloth - A flexible fabric impregnated with a special pre-mixed cement that hardens when it’s hydrated. So not only does it make creating irregularly shaped items out of concrete a lot easier, like say shelters, ditches, retaining walls, pond linings and chairs, but unlike a regular concrete mix you can’t use too much water, so it’s idiot-proof as well.
