Concrete patch


The edge of my patio has some voids in the concrete that I would like to patch. What would be the best concrete mix/patch to use to fill in this void area to fix the appearance?

I have a spare 80 pound bag of "High Strength" concrete mix. I'm not sure if that's the best to use since it has pretty large gravel in the mix. If I mix this thick, will it adhere to the underside of this void to patch it?

Or should I spring for a few bags of the 3 pound "Concrete Patch" to do this?

Just need to smooth out this edge, especially the uneven voids on the underside before I install the pond liner in the pond which this patio partially overhangs (by appx 4-6 inches)

Re: Concrete patch


I'd like to get this done today. Will the 80 pound concrete mix work for this or do I need a specialty mix here? Thanks for the help.

I'll be using wood boards below and on the side to hold the concrete in place while it cures.

Re: Concrete patch


Will the concrete go from underneath the top ledge and down to the surface, like a riser on steps? If so, I think you could use anything. If it has to hang under the top ledge, then perhaps some Tapcons or similar to help the scab hang on would help.
A concrete guy's experience would be helpful; one of them will likely comment.
I wouldn't rush it; would suck to do over IMO.

The concrete will only go in the void shown in the pic. The result will be a clean edge vs what I have now which has two voids along the patio edge.

Pics below. The green overlays show where the concrete patch will go.

Re: Concrete patch


Flowing into and completely filling the cavity is paramount in this instance so I would be using Rockite.

We don't have Rockite at any local HD or Lowes or hardware store I can find.

I'm considering these:

Re: Concrete patch


If I'm choosing, I'd go for the first one based only on the package words.

Re: Concrete patch


If you only want to patch the green area, you need grout mix, or hydraulic cement would work also, the smaller container the better for your needs.
