Need to render a big rock to rubble in an environmentally friendly way? Instead of ripping through concrete or stone with a jackhammer–or even explosives–Ecobust is an “expansive demolition agent” that breaks up rock and concrete effectively and silently. Here’s how it works: (1) Drill into the concrete or rock. (2) Mix the powdered Ecobust agent with water. (3) Pour the mixture into the holes. The agent will expand inside the hole, breaking apart the concrete or rock from the inside, saving money and time. The product requires no special licenses or permits, and the demolition creates no dust, noise, vibrations, flying debris or toxic fumes. Ecobust is exhibiting at the 2012 International Builders Show at booth 3087. Check out the product online at www.ecobust.com.
