Concrete Screenings vs. Sakrete Paver Base Under Stall Mats?

We’re working on installing stall mats in a couple of stalls and want to make sure we’re setting them up with a solid, long-lasting base, and well-draining base. I know that crushed limestone screenings (aka stone dust) are generally considered the gold standard for this — but unfortunately, we haven’t been able to find any locally near us.

So, we’re trying to decide between what is available to us:

•Concrete screenings from a local gravel yard

•Sakrete paver base (bagged) from Home Depot

We’d love input from anyone who has used either (or both). We’re aiming for a base that will provide the best compaction, drainage, and long-term mat stability.

We also want to know if 3 inches of base material (whether Sakrete Paver Base or limestone screenings) is enough under the stall mats. We’re planning to use the 3/4” thick rubber stall mats from Tractor Supply, and our stalls are 12x12, so I believe we’ll need six mats per stall.

I mentioned in a couple of other threads that we currently have Stall Savers in the stalls with play sand underneath. We’re planning to remove both the Stall Savers and the sand completely and start over to avoid drainage issues and other problems.

The natural ground of the stalls was rolled and compacted when the barn was originally built. But since we’re pulling up the play sand, will we need to re-compact the native ground before adding the new base material?

We’re planning to rent a vibrating plate tamper to compact and level the new base material, but we’re unsure if the existing natural ground also needs compacting again before we start laying down the new layers.

Any advice, experience, or recommendations would be greatly appreciated! Thanks in advance!

What’s under the screenings?

I’d go with what’s cheapest. It’s not going to drain, though. Tamped properly, it’ll be pretty impervious. Which is fine, because mats installed correctly won’t have gaps to allow anything to drain, either.

Just order a truck of screenings from the quarry. Dump it in a place where it can live. Having a pile of screenings at a farm is super handy. The bulk of the price is going to be delivery, so fill up the truck. You’ll use it–if not in this project, in another.

Have you priced concrete interlocking pavers as a base for the mats? These could be installed directly over the play sand as that type of sand is a recommended bed for pavers.

Our main barn has a concrete paver floor that we installed mats over, that was 33 years ago and nothing has moved.

That seems to be in dispute:

“Playground sand should not be used under pavers or construction because it is too fine and will wash away easily.”

Given that play sand is non angular and doesn’t lock, I’d never use it for any application needing a solid surface.

well remove the sand.

I am just showing that Sakrete who is in the business and has been for many decades (Over 86 years ) say it is a use for their bagged play sand. it is in their recommended uses.

Yes, that’s what the OP here is planning on doing.
