Grinding down cement


So here's my problem.
Husband installed a cement curb to hold back the base rock and sand for our pavers.
The cap stones are about 3/8" higher then the pavers, so we need to grind down the cement curb by 3/8" so that the surfaces are level.
The curb is about 6" wide and 16 ft long, one side has sand against it and the other is a drop off to dirt.

Are there any tools out there that can help grind down the cement curb by 3/8"

Thanks

It might be easier to remove enough pavers back from the curb and gradually raise them up to the curb height. Back 3-4' should do it. That would make it 1/8" per foot or less.
Grinding 3/8" evenly for that length will be very hard. It will also expose an aggregate pattern you might not like.

Can you explain why you think you need, " the opinion of an architect or engineer. " for this? It's a 3/8" lip of concrete and some pavers, on the ground, sitting on sand.
Maybe I'm missing some deeper issue.

The deeper issue was that he is a spammer - now gone

Ron's right. If it were me, I'd be thinking about reseting the pavers, not chipping away concrete.

But it's doable. Like if I had a gun to my head, I could make it work. I would get a couple masonry blades, put it on my oldest circular saw (one that I wouldn't care if it died). Then make some 1/2" deep cuts, knock the material away with a Hilti and a spade bit, try to even it out. Then go over that with some epoxy patch or concrete patch to even it out more. I wouldn't be expecting perfection, unless I had done it before (I have a concrete crew that refurbishes steps, equipment pads, etc, in manufacturing plants). It is doable. I personally could live with that in a boiler room or a tank farm. But my front walk or patio, I don't know.

In the end, it's probably easier and the final product will be nicer if you pull the pavers up and add some base and reset the pavers.

Yeah - cutting down that much cement is major undertaking

Grinding down cement


even i like the idea of raising the pavers & we grind conc for a living,,, otoh, watching an engineer actually WORK would be fun & a 1st most of 'em tell us how to do it

rentable 6 or 7" grinder, dust masks, safety glass's, turbo diamond cup wheel - your price under $200.00,,, raising the pavers - just time,,, seeing an engineer actually WORK rather'n stand back & watch ? PRICELESS

Raising the pavers it is.
What a chore but much more doable then trying to grind down the cement.
Thanks guys
