    Default Cut & Jack Hammer Basement Slab

    In my basement I need to cut and jack hammer about 10' of 4" concrete slab to replace 50 year old CI drain pipe. It is all gray water from the kitchen and laundry that comes over to the drain pit under the basement bath tub. In the process of converting/remodeling basement bath I removed old enamaled steel tub. This is when I noticed black pea gravel and foul musty smell from leaking/broken drain line. The connection at the bath tub drain was a banded coupling to black ABS drain pipe (ABS must have been added later after initial house construction since I can see where the floor has been cut and patched before).

    My questions:

    Rent diamond saw and electric jack hammer?

    Could I just use a diamond blade in a portable circular saw?

    Build a tent to encapsulate dust from both operations?

    Score concrete or cut it all the way through completely?

    Use PVC pipe or continue with ABS?

    I don't see ABS pipe at the "Big Box" stores, any reason?

    Thanks, Dan

    Exclamation it all sounds about right

    saw cutting that floor makes one a hell of a mess.....

    the tent is a great idea.....but you got to breathe too..


    also having someone saw cut the floor for you
    is not as expensive
    as you might think...
    and having them cut it all the way through
    is always best....


    I would make sure that their are no surprizes
    in the concrete that might get you shocked,

    the sch40 pvc is what is supposed to be used in the
    slab floors...

    it all brings back fond memories
    that I would rather forget.

    Thanks Mark,

    Do you recommend anyone in the Indy area to cut and jack hammer the floor?

    I would find a contractor that uses a "wet saw"

    No dust
    Clean cuts
    Less noise

    The ones I use have all the hand and power tools too.
    They have me work the wet vac, while they cut.

    Default like cutting clay

    i wish every cut i ever made was with a wet saw.

    The dust is bad, when dry cut. Dangerous little particles that float everywhere. No tent will hold them in.

    it out and carry it all away for you would cost.......
