Best sand for gaps in driveway bricks?

ferry

Jetwashed the drive today to find there are uniform gaps between the paving stones.
I think there is a type of sand that could be used to good effect between them and suppresses weeds.
Anyone know which type this is?

Kiln dried sand

I think it is called 'sharp sand'? Seem to recall this being mentioned several times when my old driveway was done, but I will stand corrected if someone knows better.
Good luck.

For block paving its called Kiln dried sand as said, B&Q sell it for around £3 a bag., Just brush it in with a soft yard brush on a dry day

Agree with replies 2, 3 , and 4.
The sort of product below (but it hasn't stopped weeds growing through on mine).

No sorry, sharp sand or grit sand isn't suitable, just too coarse and doesn't fill the voids correctly. It also allows new weed seeds a better purchase than fine sand. Kiln dried which is finer is the way to go.

Because it's kiln dried it will have no live weed seeds in there, but that's no advantage in the real world, fresh dandelion seeds will on the march immediately.

Kiln dried sand is just building sand that's dry enough to brush between the gaps. If you have a big budget, or many hours of time, you can point the blocks, but assuming it's small 'monoblock' you're talking about this would be a waste of time. If the drive is larger paving stones then pointing will be worthwhile. You get brush-in compounds that you water in and then set in situ, but they are expensive.

Kiln dried sand, move on.
