Concrete Saw For Residential Basement Floor Cutups


im a plumber and typically use an electric jack hammer to bust up floors. We constantly run into really hard concrete. Im considering buying a concrete saw. Im looking at a Husqvarna k760

how would a gas saw work in a residential basement?
it needs a hose hookup..which could also be an issue in a residential basement...would a spray jug by a 2nd person work?

electric saws get bad reviews....otherwise thats probably a smarter way to go...

ive got a few jobs coming up where i need something more than a jackhammer and dont want to spend 8 hours jackhammering

advice?

Re: Concrete Saw For Residential Basement Floor Cutups


As much as I love gasoline chop saws,I would not run one in a basement. I would probably use one of these https://www.amazon.com/Evolution-DIS...70_&dpSrc=srch


With a real good shop vac. with a dust deputy cyclone separator.

Re: Concrete Saw For Residential Basement Floor Cutups


The water isn't an issue if you use a shop-vac.

The exhaust will burn your throat and eyes and lungs. For days. Even with what you think is good ventilation.

Don't ask me how I know this.

Re: Concrete Saw For Residential Basement Floor Cutups


Having somebody stand there with the sprayer does not totally eliminate dust

Probably only 85% of it so 15% in an enclosed space is a lot

You need to completely flood the blade in order for it to be mostly dust free

I have the husqurvana electric saw And it works good however it does not have nearly as much power as the gas saw so I would not want to cut through a lot concrete with it. And it uses a lot of power and has a tendency to blow circuit breakers

Re: Concrete Saw For Residential Basement Floor Cutups


Hydraulic saws are the king.

Fire/Rescue teams use them everywhere, indoors, hazardous environments, in the rain, whatever.

They are a little pricey, and you need a hydraulic power unit to run them, but, hey...... They're awesome.

Go ahead and use the gas saw. You will only do it once. Guaranteed.

They don't make masks for running a gas saw in confined spaces.

Just like Seven said. Don't ask me how I know.

Hydraulic wet saw all the way.

Re: Concrete Saw For Residential Basement Floor Cutups


I have used a gas saw in a basement but used air movers to properly ventilate it.

It was ok since we had plenty of airflow

Re: Concrete Saw For Residential Basement Floor Cutups


Sub it out if you don't have the proper equipment and don't enjoy doing it.

Full blown 90 lb air driven jackhammers are a lot quicker than electric...walk behind basements saws can be rented and is proper protocol. Invest in dust containment systems...you need them in this environment.

My average 100ft interior french drain systems are usually busted out by noon...it's getting all the chit out of there that I hate. Conveyors are your friend here.

Same here, but it still stinks the house up. I rent an electric and make sure I can plug into a 20A circuit.

And use a garden hose attached to the saw, with a helper on shop vac duty.

Re: Concrete Saw For Residential Basement Floor Cutups


Here is my electric which I use indoors but no way would I use it to cut a concrete floor. That would be miserable for more than a foot or two. It just doesn’t have the power plus after a few minutes I wouldn’t be able to stand up since my back would be in A locked position. Most electric saws are not ergonomically designed to cut floors

Hence why I call it the breaker popper...

It has a 20A twist lock end but comes with a 15A adapter....don't even think of plugging it into a vac....you really need a 20A supply and another breaker for your vac.

Well yeah, they work much better with a blade in them.

For your back, you can use a walk-behind model. But that pretty well limits you to floors only. Either way, I'm too cheap to buy one. For my limited usage, I just rent whatever I need for a given job.

Re: Concrete Saw For Residential Basement Floor Cutups


A four stroke concrete floor wet saw with two or more Large fans, one in one out, works faster straighter, and much easier on the backs....

the straight and deeper the less the patch work required.

Also catalytic converters can be installed that grossly reduce toxic fumes after warm up, ( warm up out doors if possible)

remember a slight angle(wider at the top of cut) if possible on one side makes the spoil come out easier....

Plan ahead for fittings and finger room. Generally any less then 12-16" away from a wall will break off any way.... but allow for wavy oversized footers....

If I owned a skidder, fork lift, or mini hoe with a hydraulic optional circuit, I'd install a Hydro motor on an old 8 to 13 HP target floor saw to use cutting indoor concrete, and buy a hydraulic concrete chain saw if I did alot of floor demo.....

Or air powered if I owed a ~100 CFM towed compressor......

Damm I was wondering why that saw didn’t cut worth a chit! Haha

Common i am too cheap to have enough blades because I have 4 saws and rarely have more than 2 saw blades!
