What is Dexpan

Dexpan is a gray non-toxic powder used to break concrete, rock and boulders. 

Dexpan resembles Portland cement in appearance and is made of environmentally friendly natural minerals with slaked lime (calcium hydroxide) the major ingredient. 

Dexpan Demolition Grout is also called a Non-Explosive Controlled Demolition Agent or Soundless Chemical Demolition Agent. 


How Does it Work?

Dexpan is mixed with water and poured into pre-drilled holes.  A chemical reaction occurs that generates heat and a gradual expanding in volume that creates 18,000 PSI of expansive force breaking the strongest concrete or rock.
