can exposed aggregate concrete be cut...


...without trashing it? I have a sidewalk leading up to my house with a small pad connected to part of it. I'd like to cut off the pad, leaving the sidewalk only. It'd be about a ten foot cut.

Thanks for any suggestions

Go for it. You can use a circular saw with an abrasive masonry blade but using a wet-diamond blade would give you a cleaner and faster cut. Just run a little water on the cut as you proceed. Don't get in a hurry and don't scorch the blade if you use a diamond blade.

Ayuh,... I completely agree, Except,...
For a 10 foot cut, I'd go rent a walk-behind roadsaw...
With a 14" diamond blade, 'n water runnin',...
You can follow a line for a really straight cut....

A handheld gas demosaw would work too,...
It's just harder to get a straight cut, that Long...

With a 7, 1/4" circular saw, you'd be Days cuttin' a 3" slab, 10 Feet...

It is not very often I disagree with Bondo, but there is a very nice little rail and water rig you can clamp to the Skill-saw and I get great results in little time.

I can't remember the brand name but it has a wheeled plate that you clamp to the Skill-saw and an attachment for a hose that will spit the water onto the blade as you cut.
It also comes with a GFI gizmo.
It's great and I think only about $40.00.

I will look online for it.

Andy.

thanks guys. I was worried about the blade not cutting thru pebbles cleanly and leaving a ripped up or jagged edge.

I would bet about 30 mins, we cut out squares in slabs all the time for piers, a 12"x12" (4 LF) takes about 10 minutes.

Some of the stones will break, some will cut, some will be spit out of the path of the blade. All and all it can be cut nicely but the resulting edge won't be pristine and sharp enough to skin a deer, it will still just be cut concrete when it's all said and done.

You guys must have some huge circular saws if you can cut through a 3-5" thick concrete slab with one.................

You don't have to cut all the way through it and you know that. What, are you just trying to pick a fight?

I know that the safest way to remove the slab is to cut all the way through the slab, not to mention that if there's any steel in the slabs, it will be in the bottom half anyways.
