This "How To" DIY video will show you some of the techniques I've learned when breaking up concrete. Using a 35lb Makita electric jackhammer and 10lb sledgehammer, this video will take you through the process from start to finish. I choose a fairly easy to handle electric jackhammer and ended up breaking the concrete up into small pieces, so I could reuse it a base layer of gravel.

Here is a link to a newer version of the demo hammer.
