Spray Grancrete over a frame of
Styrofoam, metal, wood-even woven sugarcane stalks-and in 20 minutes you have a waterproof, fire-resistant structure that has more than twice the strength of traditional concrete and can withstand extreme temperatures without cracking. A liquefied concrete-like mixture of sand, ash, magnesium oxide and potassium phosphate, Grancrete descends from a product developed to encase radioactive waste. And since it takes hours instead of weeks to build a home, it´s poised to provide low-cost, high-quality shelter to the estimated one billion people who lack it. $20.50 to coat 15 square feet

There has been a lot of testing and experimenting over the last year with Grancrete and a whole new slurry of uses have been developed. Some interesting and cost effective ways of using it are to make custom countertops at a fraction the cost and weight of granite or coating roofs, floors, bathrooms, driveways and concrete repair. One of the most over looked features with Grancrete is its ability to stand up to the wear and tear of salt. In fact, Grancrete can be mixed with salt water and even beach sand as the aggregate and have no reduced performance. I can’t count the number of places where I’ve seen pitted out concrete because of salt use either from snow plows or coastal sea spray. The best part is that Grancrete is considered “Green” and is far more friendly to the environment than concrete.
