What is this Concrete finish called?

[72Anthony]

Any idea what this type of concrete finish/texture is called?

I like the look and am considering it for the driveways/flatwork at our new house.

These are the walkways around an office building in Houston and the pictures were taken in 2007. The building is near my existing office, I need to stop by and see how it is holding up.

Thanks,
Anthony

It looks like a form of 'exposed aggregate' finish. A set inhibitor, also called a retarder is sprayed on the surface, which allows you to spray off the cement paste after the underlying concrete has set enough to keep the stone from being dislodged. You can sprinkle extra stone of any color you like onto the concrete and float it in to get different effects.

Almost looks like the finish you can "paint" or "spray on" a garage floor?

I think it's a salt finish. You press course salt into the concrete and once the concrete sets you wash out the salt pieces.

What pattenp said....

My Godfather laid this down near his poolside but he tinted his...looks very nice!

I agree with PattonP... looks to be a salt finish.

Definitely salt.

Salt makes sense.

Around here it would be "lasts a year". The snow would melt into all those holes, re-freeze and blow the concrete apart in the first winter.

Almost looks like it has been ground and polished.

There are 2 rock salt finishes and that's the extra coarse finish. Rock salt for ice cream makers is a little more finely graded.

Almost looks like it has been ground and polished.

You could do both if you wanted voids in the surface.

As an aside I have some stamped concrete that has a bit more texture than what you show. I find that every depression is a small collector of mud and it requires constant cleaning. Just something to be aware of.

Some type of exposed aggregate.
