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. |

They just do mono slab here (or slab over stem wall). There is a 16" deep (total) ring around the house with 2 #5s in it and a 4" slab across the floor with 6 over wire in it. If the ground was properly compacted, that ends up being plenty stable. I have terrazzo over than and there are no cracks here after 53 years. The stucco over plywood is far more troubling, particularly around penetrations like windows and doors. A couple companies in Atlanta got their ass sued off over that. Here it is usually stucco over block. By the time you buy all of the hurricane clips for stick built, block ends up cheaper or at least comparable. You basically have to clip every joint where the sticks meet on every load bearing wall and post and anchor that to the footer. In block construction you just dowel the cells every 4' and pour them solid, then you pour a tie beam on top (with 4 #5s) and embed clips for the trusses. It goes a lot faster. The 2400 sq foot house they are building around the corner went from pouring the slab to truss in less than 2 weeks. They lost some days for concrete set and inspections too. The block crew was at tie beam in a day after the slab set. |

For some reason they make you dig it all out, compact it and then poor the foundation... My other three homes I used to own were not cable tensioned foundations. Same type stick and stucco.

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 ? https://buyersask.com/lesson-4/post-...n-slab-lesson/ John T. 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. https://www.youtube.com/watch?v=7skQS_AFuUw Never heard of it in residential either. I'll be gol danged. I bet that jumps the price up. They just do mono slab here (or slab over stem wall). There is a 16" deep (total) ring around the house with 2 #5s in it and a 4" slab across the floor with 6 over wire in it. If the ground was properly compacted, that ends up being plenty stable. I have terrazzo over than and there are no cracks here after 53 years. The stucco over plywood is far more troubling, particularly around penetrations like windows and doors. A couple companies in Atlanta got their ass sued off over that. Here it is usually stucco over block. By the time you buy all of the hurricane clips for stick built, block ends up cheaper or at least comparable. You basically have to clip every joint where the sticks meet on every load bearing wall and post and anchor that to the footer. In block construction you just dowel the cells every 4' and pour them solid, then you pour a tie beam on top (with 4 #5s) and embed clips for the trusses. It goes a lot faster. The 2400 sq foot house they are building around the corner went from pouring the slab to truss in less than 2 weeks. They lost some days for concrete set and inspections too. The block crew was at tie beam in a day after the slab set. If you are stuccoing, ICF is the way to go. Great in Hurricaine country too. |

ICF looks interesting but I have only seen one building using them here. They just tore it down. I would have liked to see how hard that was to do but it was gone in a day. (Commercial property going another way) I have seen a few strange things over the years here. When I was working I inspected a Y-Tong concrete building. It was tilt up construction with all of the walls coming in on a truck. (A kiddie jail). The stuff was so soft I asked if they were worried a kid would tunnel his way out with a spoon. They said they were putting mesh and stucco over it on both sides and hoping the little *******s didn't figure out it was not solid concrete. They built a single family up the street that was foam panels encased in sheet steel. It was put together with a screw gun and angle. |

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. 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. |

We don't see a lot of stucco, but we are seeing a lot more with ICF taking hold. |

Almost no basements in southern Nevada, but there are some (few). Worked at one site that built monolithic poured walls, that allowed walk out access to the pool area and back yard area. It was basically a complete living area, bedrooms, bath , theater and entertainment for the kids. A place to send the brats. Flash floods are bad here in the desert with just a few inches of rain. Hard pan soil is dug out and land built higher, compacted again for the "100 year flood", so the government says :-) Nevada is not a salt water sea anymore. |
