Control crack filler

[Gozo]

I have stamped concrete leading from the garage pan to the driveway. There are control cuts in the concrete both lengthwise and widthwise spaced about 10’ apart. It’s been in place for about 5 years. Every fall I clear the acorns and twigs and stuff out of the cuts every few weeks so when we do get a freeze the **** doesn’t dam up and collected water doesn’t freeze and bust chips out. There’s a few spots this has happened with. I’m looking to fill the cracks with a flexible sealant that won’t easy pop out over time.
What do you guys suggest? Ideally something easily available locally. I got some Sikaflex at HD a few years ago. The stuff was solid in the tube.

Sikaflex works well.

Not the same reason, but this stuff works great to fill cracks in concrete prior to laying vct.

Oh, and it remains flexible and approved for filling in expansion joints that need to remain flexible

Sikaflex works well.

This. I’d clean the Crete edges really well so it sticks to it. Hd has it on shelf. Very messy so if concerned tape edges. Remove tape after application. Use foam backer rod if big gap

The Sikaflex is magic,I just filled a bunch of cracks and separations in my driveway easy to work with. Just make sure you check the expiration date on the lid in the end of the tube.

Another vote for Sikaflex. I used it on my saw cuts in my garage. Just make sure to clean them really good since its been in place for a while now. I used painters tape on both edges so I could use a putty knife to push it into the joint. Pull up the tape right after application and let cure.

Went with the Sikaflex. According to the usage guide calculations, I’d need a bit more than 2 of the large tubes. Wound up using 5. Not too bad on the drips outside the cracks; had to do some cleanup with a razor knife and some screwdriver scraping. Thanks for the input. I’m gonna give it 3 days to cure before driving on it even though it firmed up pretty well over night.
