Sand or grit?

[Martin C]

Pressure washed a drive today, no sand seemed to be removed in the process, just a very small amount of grit/sharp sand.
I know some pavers should have grit & not sand but I’m unsure what to refill the gaps with?

Thanks, can’t find that locally for some reason, will it cause a problem if I just sanded it, the gaps just seemed empty once the moss was removed from them, no sand & like I said..a very small amount of what looked like sharp sand blown out.
Is it to do with drainage issues, if so I can post a pic of the drainage there?

I noticed some of these new thick pavers don't have anything between them. Usually flat car parks to help the rain water drain away. ?

Ah, that might explain it. Not sure what to do now, this is a new one for me, I’m so use to re sanding afterward?

Ask the customer and see what they say. There's a new build estate I work on that was built on marshland and they have permeate gravel due to drainage issues.Last thing you want is getting blamed for not providing stability for the blocks if they need something inserting.

If they come.backback and say yes it needs something then just let them.know it will be an additional cost.

I'd use kiln dried sand
