We never sealed our concrete drive.

No sealed driveway here either.

I don't believe many people seal their concrete driveways, but sealing it can increase the life of the concrete and make it easier to clean, more chemical resistant, and resistant to freeze thaw cracks. When we pave our driveway (hopefully this fall) I am going to seal it with a cure and seal product that is applied right after it's finished. For what it's worth, I work in commercial and industrial concrete construction and we seal all exterior paving and parking garages.

I regularly sealed my asphalt and interlock paving stone driveways.

Asphalt works best and longer, sealed. Concrete I don't know about.

We have our asphalt driveways sealed annually (my neighbor does it twice a year) When we had a brand new asphalt driveway put in, they told us to wait a full year before sealing.

It's a complete waste of money and effort. The only thing it affects is the aesthetics. It has zero affect on longevity.

I've never sealed my (concrete) driveway, but it has a couple nasty cracks. Perhaps I should've?

We have a large driveway with Belgard pavers and they were sealed when installed. The sealer is supposed to help with preventing staining and it does enhance the color of the pavers.

What I really like about pavers is that if one gets broken or badly stained, it can be popped out and a new paver installed in its place. Also if the ground settles, you can lift up all the pavers in that area, regrade the soil and reinstall the pavers. It also helps that we live in CA and don't have to deal with any freeze/thaw issues.

I'm curious as to why you say that, Sophie, after hurttholler's post. I can't imagine in commercial construction they'd spend the money if there wasn't some benefit. Please explain how you know this.
