Breaking more hard Granite without explosives

Описание к видео Breaking more hard Granite without explosives

As part of a larger housing estate development project I had to bust out a large piece of hard Granite rock to make way for underground services. This is not difficult when you can blast it but on this occasion we were working near a live fiber optic cable and probably blasting was not a really good idea... Expando chemical cracking agent to the rescue again - drill, mix, pour, break.
