polymeric sand or liquid polymer for concrete filling?

I've got a handful of cracks in some driveway spots that I want touched up soon, but what would be the best application? Crack sizes range between hairline to almost 3/4"

I used Quikrete concrete patch to fill some deep gouges and a few holes in my slab, during bathroom renovation. I found it easy to work with and it smoothed out nicely... Watch some vids on youtube - the key is let is set for a while then take a damp sponge and smooth it out (before it hardens completely).

I should have mentioned before, but these are cracks due to a massive tree uprooting some of the driveway.

How long/wide are the cracks?
Posted on 7/25/25 at 1:48 pm to The Mick
no more than 3/4" wide, 6' long

I did polymeric sand and it was fine for a while, but I've had to re-fill the cracks a couple of times over 10ish years.
Looks really good though when they're full. Came out same color as my patio slab.
ETA:
But could not be easier and isn't expensive so I'll probably just keep doing this. I think our hard winters in East TN do something to weaken/loosen it.

They make a concrete crack filler, comes premixed in a bottle. I’ve never used it though…. Might wanna check that out.

There are a ton of those I'm noticing. I was hoping someone would have experience with one and drop their results/opinion on it. Sand might be the way to go for longevity.

I used the Quikrete epoxy from the bottle. Good results, sets hard. Use a backing material in the crack
