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). -- for full context, visit http://www.homeownershub.com/mainten...r-1119171-.htm |

(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. |

You can also do it with a carborundum blade but it will go a lot slower |

(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. 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. |

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. https://www.lowes.com/pd/Kobalt-Long...Spade/50299967 Concrete is pretty hard to break if it is sitting on compacted soil. |

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 |

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. |

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. |

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. |
