I had my basement floor sawed. He sprayed the whole damn basement.
WTF? he could have used a drop cloth or somethin. Eventually discovered
the stuff was in the furnace and causing it to not function as well.
What a mess. And even after they use the saw, they will probably have
to jack hammer a bit to get the concrete out anyway. And those clean
cuts don't heal as well, at least in my case.
However, the cleanliness will depend on the quality/self-respect of the
people you hire no doubt.
Make sure its that thick... If its only 4" you can do it all yourself.
Get a drill and verify the thickness. 8" thick, get someone else to
go at it. 4" will only take a few hours and is a good workout.
I broke up my basement floor to put in sewer lines. Not a bad job.
If you want a real clean cut.....
Use a circular saw with an abrasive blade (get two they are cheap)
Put up plastic liners around all the openings and open the window.
A nice fan will be ok in the window
Score it and cut a little bit in, This will give you a nice clean line.
Use a sledge hammer or something similar to break it up.
If you want to make it even nices, drill holes all the way through in
a sort of grid pattern. When you break it up, the cracks will form
from those lines.
Well, initially I was going to tunnel, but then many suggested tunneling may
compromise the foundation and footing, so now I am thinking fixing it from
above, but if it will create a mud pond and damage my cabinets, I did not
consider the issue of settling, are you saying the weight will crack the
new PVC pipe? Can I not put sand and compact it before I pour concrete? I
don't know how deep the pipe is though... is this a real concern?

Cutting up a congrete slab with one of those would be like roasting a
20 pound turkey over bunsen burner.

here is information on different type of sawing
The Wire cutting is something that COULD be really good for your
application if they can drill a hole in 2 places and get the wire
threaded it will be cutting from the bottom this will meal all the dust
and mess will be in the hole rather than the kitchen.
Normally when cutting concrete the "wet" method is used where there is
a steady stream of water on the blade this provides cooling lubrication
and debris removal. You should be able to have plastic put down on all
of the surfaces and the doorways were well as above depending on the
working room they may be able to tent the work area one of the big
things 2 is air pressure.if they reduce the air pressure with a fan
running outside in the work area the dust will not be able to get very
Ask to speak to people who have had the company make holes in their
houses to get an idea of the mess
CTI pioneered the use of the diamond cutting techniques shown below.
While each has its own unique advantages, all share an ability to
provide fast, clean and non-destructive removal of virtually any
construction material. If your project requires surgical precision, a
cost-effective alternative, or innovative engineering in sensitive
environments, CTI's cutting and coring techniques are your only choice.
DIAMOND WIRE SAWING
A motorized system of drive and guide wheels pulls a diamond-encrusted
wire around - and ultimately through - the object being cut. To cut
voids from a larger structure, pilot holes are first drilled into the
structure at the ends of each cutting plane. The wire is then fed
through the holes to create the loop that will sever the spoils from
the remaining form.
Typical Materials Cut:
Heavily-reinforced concrete, solid stainless steel and rock.
Limitless dimensions and volume.
Typical Cutting Applications:
Crossovers in extremely thick structures.
Demolition of mass-concrete forms such as dams, towers, piers and
Cutting of structures under water or otherwise inaccessible.
Cutting of fixtures with complex, irregular shapes.
Precise cuts with no over-cutting at corners and smooth finished
Lack of vibration, noise, dust and flying debris enables "clean"
demolition in sensitive and occupied areas.
Controlled cutting leaves remaining structures safely intact.
Quick, versatile, safe and economical alternative to conventional
Depending on the need, circular, diamond-tipped blades are mounted onto
a range of power units - from walk-behind slab saws for cutting level
surfaces, to track-mounted wall saws for cutting steep or vertical
inclines, or even handheld units for smaller cuts.
Typical Materials Cut:
Steel-reinforced concrete, pre-cast concrete, asphalt, stone walls and
cobblestone street beds.
Up to 30" deep
Typical Cutting Applications:
Paved surfaces such as roads, runways and bridge decks.
Walls and suspended slabs such as floors and roofs.
Access-way breakthroughs for stairways, elevators, windows and doors.
Trenching and crossovers for mechanical services and cabling.
Precise cuts with smooth finished surfaces
Quick setup and sawing minimizes down time and traffic disruptions.
Variety of power sources to accommodate all available power and exhaust
Cutting in confined spaces.
Thanks, I called about ten concrete contractors and most use the wet saw.
Cannot find anyone who will do the wire cutting, and someone else suggested
drilling holes at short interval then chisel out by hand may also minimize
dust, can't find anyone to do that either. May be this is a too specialized
and require some high tech contractors? Can't seem to find them if you know
of a link to find such contractors please let me know. Thanks in advance,
On 7/27/2005 9:29 PM or thereabouts, miamicuse appears, somewhat
unbelievably, to have opined:
I had a couple of leaks under the slab repaired in my previous home. My
plumber brought a jackhammer and chopped out the hole needed himself in
just a few minutes time. Of course, we're talking about holes that are
somewhat smaller than your 36x36. I replaced the dirt, compacted it to
the best of my ability, and poured ready mix in to patch up the holes.
Then I replaced the broken ceramic tiles and grouted them. No problems
at all after several years. One leak was in the kitchen and the other in
the downstairs half bath.
As a child, my parents thought I was an idiot-savant.
Now, however, it is rather clear that I\'m simply an idiot.
