I have a concrete driveway with a low spot in the middle of 1 of the squares. Been this way for years.

I've ignored it. But then my daughter's new house has a low spot in their garage where melted snow is puddling.

Any recommendation on something that a noob do it yourselfer could use for these without cutting things deeper? I DO realize that anything would be feathered ./ very thin if we don't cut the edges deeper. But they are more of a cosmetic thing - even the one outside. It's been this way for a decade.

On other squares on my driveway though, i am getting a couple cracks. I will be power washing / sealing with behr product this summer. That will help prevent more?

I had filled some of the crack with slika self leveling material I use in the expansion joints. (the cracks are longer now).. Is that silka material good for the cracks?






Thank you!

 

One would think there should be a self leveling material, like used for tile, that would work but that kind of material is not intended to be used outdoors, where it's exposed, exposed to traffic, and possibly freezing conditions.

Unless you want to tear the section out, it's just not repairable!

 

Thanks!

 

Oh, what's your thoughts on sealing the driveway / dealing with cracks?

I have that silka self leveling caulk material in the expansion joints. with backer foam under them when there' a deep gap. The caulk has buckled a little in some spots. I'm pouring sand in there to fill gaps below the backer rod - not sure how much open space is under there. I think water gets under there, freezes and panels heave a little / that's the cause of at least some of the cracks. there's about 14 of these 10x10' panels. only 2 have cracks, so it's not affectiing most of the driveway.

 

Actually I have the same situation, my long cement driveway was not poured with any gravel/drainage (cheap builder) so for the first couple winters the slabs would heave because water would get in there, not drain and freeze.

For about 10 years I also installed the self leveling material but even with that about every couple years I would have to repair sections because areas would still get wet, heave, and tear the sealant.

This summer I had a few slabs mud jacked that they recommended using plyometric sand which I had never considered for a driveway.

Couple months of tearing out all the old sealant but it was a simple easy installation of the sand. It certainly has not been a typ winter but so far nothing has heaved and any repairs are very easy. Time will tell if this is a preferable solution!

 

This is a very easy diy repair. Go get yourself some rapidset mortar mix from your local orange store. Use a wire brush to clean out any loose debris. Wet the spot and then apply rapidset. It will hold. Sponge the patch to blend in with the surrounding concrete. Rapidset is good for outdoor repairs. I've done it. It's good.
