Finland probably more blasters than any other country in the world. The whole country is basically one big chunk of granite.

Thats true! and up and betveen the granite there is clay... so no need for dozers here
but concrete building implosions are extreme rare here! one reason is that it's rare that any bigger buildings at all becomes demolished, they are always doing extremly costly renovations and trying to figure out something else to do with the buildings...
In any case, finding a guy who knows exacly how to drill, how much explosives to use and how to cover the thing in the right way, is quite hard here around.

Check out the HB10000 by Atlas Copco. It uses a Krupp design. It produces 12,000 ft. pounds of energy. The drawback is it needs to be mated to a big excavator (80 ton).
Indeco also makes a great hammer. It's model number is the Hp 18,000.

For drop hammers, I was working on a project recently and the contractor was using a Fractum 400 and it was making pretty fast work of a meter thick slab. Plus it will fit on almost any machine you currently have.

FRACTUM - Home

the problem is that the space around the building is very limited, thats why i have been thinking about a dropp hammer, to get more power out of a smaller carrier!
I really don't think even anyone here in Finland own a HB10000 hammer, even 80 ton carriers are quite rare!
The advantage with the dropp hammer is that it pulverizes the concrete, so picking out rebar is quite simple.

Thanks Nuke for the link!
