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).

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

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.
