brushing sand in the driveway

[Lk1980]

Hi
I just jet washed my driveway last week and after it had dried completely, I got a weed inhibiting sand and brushed it between the blocks. I have noticed over this week when it rained, some sand has been washed away leaving my concrete blocks a very thin spacing between the blocks. - I am worried if sand keeps on vanishing when it rains, weeds may start growing between the blocks?

Can someone please help and advice how to ensure the sand does not come off between the blocks.

I am planning to seal my drive once the weather is a bit dry and sand has settled in between the blocks?

Many Thanks

Chances are the sand has got washed in by rain not unusual to need to redo a couple of times, just wait for a dry spell and re-sand.
