    The first pictures are from a garage prep job from last week. These beach houses are on a flood plane so we also dug for a retaining wall/flood barrier.

    The next pictures are from a warehouse renovation. The contractor spent 6Hrs with a 90lb air hammer in the first picture.:dizzy: The slab was 18” thick.

    At 18" of concrete looks like he might have bit off a little more then he could chew 6 hrs later??????:usflag:

    I don't think I would be jack hammering for 6 hours. In 1 hour if it wasn't making a dent I would have gone to plan B.

    I wondering what he was using, A Bosch Brute ?

    Is the warehouse in Richmond ?

    I can see a 18 inch thick slab if it was sitting on soft ground.

    The warehouse is in Richmond, it was originally built as a fertilizer factory.

    When I arrived at the job the contractor was using his forklift as a battering ram to take down cinder block walls. So I guess 6hrs chipping concrete must have seamed ok to them.

    I kinda figured it would be in Richmond if they are using 18 inches of concrete so the building can float on top of the quicksand :laugh:

    agree...he had the compressor there, why not go with a rock drill and wedges...i had to bust out a piece of granite last year...after 1/2 hour with the hammer i switched to the drill...little more of a pain but atleast you are getting somewhere

    after an hour without making a dent in concrete like that, I'd have just gone and said screw it, we're renting a big track hoe with a hammer on it.

    Ron, how much flat rate for the concrete breaking?

    Wedges work good for rock, I don’t know how they would work in reinforced concrete? Probably faster than chipping it with a air hammer.
