    Cutting Concrete?

    I was hoping to get your input. This weekend I plan on excavating for a new walk-out out basement that includes cutting through the existing 8" poured concrete foundation walls, excavating the crawl space, and pouring a slab, and installing french doors to create extra storage and a shop for me! All-in the project should take about a month to complete.

    What should I use to cut thru the existing 8" concrete foundation walls?
    Thanks

    8" is going to be a tough thing to do with any ordinary home handy man type tools. Even renting a gas concrete saw is only going to give you a about 4" or 5" depth. Meaning you will have to cut from both sides. You might want to look at hiring that part out.

    Do you plan on turning the crawl space into a full high basement? If so you need to worry about the foundation. Lowing a basement floor means you need to extend the found walls down, and pour new footings and under pin it all together.

    I agree with Sawdust...hire that awful job out. Let somebody young, strong, and stupid with hopefully the right tools do that backbreaking job.
    I have more ideas than ambition.

    There is a concrete saw out that resembles a chain saw, it will cut 12 or 14 inches. A lot of rental yards around here rent them out by the hour,day, week or as long as you need it. here is the link www.icsbestway.com
    Good luck with your project

    If its has a crawl space only it sounds like footings. If you are exposing the grade it doesnt sound like you will have frost footing depth again? Maybe I dont understand what you are doing.

    Make sure you have 42" or whatever your local code calls for of wall/footing under the dirt when you are done or you are going to have problems with the whole house.

    These guys are right, its a dirty job. The pro's often uses saws that run on tracks that you anchor to the wall. An amateur can do it but I sure wouldnt want to be cutting half way through in a crawl space. If you do it dry, you are going to have more of a mess than wet !!

    Amen on cutting it with a wet saw. And make sure there is good ventilation for the CO from the gas saw.

    I think I'd need a little more info..

    Are you going from a 4' crawl space to an 8' ceiling basement? Your excavation could be an enormus task! Just trying to get a handle on the scope of the project.... The wall cut may be the smaller part of the entire project.........~Scotty

    back to your question. drill holes in the corners and snap lines inside and out. then follow with your rotary saw of choice.

    we used a chain concrete saw at work to cut out for a gantry crane. was a sweet pc of equipment!

    Thanks to all for the input. The "crawl space" is mostly excavated already. In fact, the original plans for the house called for pouring a slab in there originally. The crawl space has approximately 7' of clearance already, so I only need to go down another 8-10" to allow for stone and slab so no underpinning is necessary. Once I cut the opening in the foundation wall, I plan on renting a Dingo (walk-behind front loader) to dig down the 8-10". After that, stone, compactor, slab, french doors, electrical, and voila!

    I'll be sure to post pics as the project comes together. This weekend I start the excavation and hopefully wrap the project in about a month.
