Default Cutting trench thru concrete/rebar floor?

I'm a woman and do a lot of my own home remodel/repair work... sooooo, How's
the best way to cut a long thin trench into a concrete floor that has rebar?
Got a kennel and want to install a trench drain in an existing floor. The cut
will be about 25ft long and about 8-10in wide. What's the different ways a
homeowner can use to complete the task? (Mind you I'll have to rent the
tools).

There are saws that us abrasive wheels that will do the job. Should be
able to rent one and buy the blade.

You may also want to call a concrete cutting specialist. I've used them
twice and the price was reasonable and it was done quickly. Most will
give you a price on the phone. Remember, you have 50 feet of cutting to
do to make a 25' long trench.

Cutoff saw with a diamond blade. It will go right through it. They may
make you buy the blade tho.
You can also do it with a carborundum blade but it will go a lot
slower

If you own a typical 7.25 inch circular saw, I have personally used
these Skil brand diamond blades to cut reinforced concrete.

http://amzn.to/2irAcOY

It will be far less expensive for you to buy this blade and an A/C
powered circular saw then it will be for you to rent a specialty
concrete cutting saw.

My best advice is to make several shallow cuts until you reach the
desired depth, advance the saw slowly and wear hearing and vision
protection.

The desired depth will be a couple inches less than the maximum depth
possible with a 7.25" blade. If you make the cuts on both sides and
start digging the dirt out from the edge, the concrete will be easy to
break sitting over the cavity you make. You dig several inches out,
under the part you are removing and hit the concrete with a big
hammer. It actually goes faster than it sounds if you have 2 guys
working. Use a narrow trench shovel.

Concrete is pretty hard to break if it is sitting on compacted soil.

Did I miss something? How do you know the thickness of the concrete
she is cutting? Are you speculating?

Probably won't cut deep enough. A concrete saw (rented) will AND you can
stand up while you cut

Default Cutting trench thru concrete/rebar floor?

If the slab most common in a home has post tensioned cables inside, thats a severe safety issue. my brother had this come up in his home, a below slab water line broke,

he had to have his slab x rayed to avoid hitting any cables.

i doubt this is a issue for the OP but might be a issue for someone else

My foundation is cable tensioned. You notice a cable (s) sticking out
of the foundation an inch or less --- not in all cases, though. Some
home builders put a stamp in the garage pad to indicate the slab is
cable tensioned (no all do).

It is worth knowing before you cut the concrete. I was lucky we
missed the cable in a master bath reno.

Here's a " Learn something new every day " moment, for me.
I had no idea that this was ever used in homes !
Is it used for certain special cases ? like no proper footings or
architectural design .. or something ?

This video is a builder in AZ. I'm in NV. I had never seen this
construction or knew about it until after I bought the house.

Stick built and stucco exterior. Never have had a crack in the
drywall.

Yikes
It would never occur to me that residential 1&2 would do this.
Of the 2 states I have lived and built in, you are lucky to see steel
although Florida is better than Maryland was. It is still just going
to be wire mesh or rebar.
In the 70s in Md, rebar in the footer was not even that common.

Why are some houses made with a foundation throughout? Here they're just foundation under the walls. The floor is wooden, 2 feet above the ground, which means you can get under easily to run cables and pipes.

Here the minimum code is 1 meter crawl space, crawl space floor must be 101.6 mm concrete, exterior footings must be sitting on undisturbed soil below frost line.

What is the point of the concrete where there isn't a wall on it? You don't need it in the middle of the house.

And 1 metre?! You must have a lot of steps to get into your house.

They build a lot of slab on grade houses here.
Even when they are on a stem wall, they generally fill the box and
pour a slab. It may be termites. If they get loose in a wood floor you
might end up dropping into the crawlspace.

Only an idiot would build/buy a house on a slab in this climate.

For this area, a 10% slope away from the house is desirable for proper drainage. Finish floor of house is usually 2 steps above grade.

And a concrete floor in the crawl space controls moisture and keeps critters out. Also makes it easier to work on electrical, plumbing and HVAC.

Insanity, covering things like water pipes with slab. I'm glad I have a wood floor with a gap.
