Expansive Mortar, Non Explosive Demolition Agent from Expando

Pan Civil was engaged to widen the road and remove boulder hazards from the road shoulder in the Moonbi Hills region of NSW.

The rock was granite and extremely hard. Some of the boulders were up to 200 Tons. Neil Champion director of Pan Civil said “It was uneconomical to break these rocks using the hammers on our excavators. So we turned to Expando.  Drilling was done by hand and by machine. The splitting was taking between 24 and 72 hours depending on ambient temperatures”.

The photo’s Neil provided are great examples of what can be done using Expando.
