Gaps in block paving
Discussion

That's cement, you're maybe thinking of ready mixed mortar? Either way you'd need care to not leave cement stains on the block surface from the excess.
Though for jointing in block it could have been all sorts already in there, like kiln dried sand then a block sealant binding it.
It's had kiln dried sand in it, the whole patio was lifted and relaid 3 years ago. We have a real ant problem and the builder was supposed to do as I asked and lay the blocks on concrete so the little f*ckers couldn't burrow their way up the gaps ... but he just did it his way and laid them back down on compacted sand.Though for jointing in block it could have been all sorts already in there, like kiln dried sand then a block sealant binding it.
So would than cement mixed with the sand the bastids have pulled out do the job?
What you have there is called flexible paving (the kiln dried sand being the indicator) so you can't really mix a different laying method in to that. The builder is right but he should have explained it to you.

It's made of hard sand at a guess.
Caught the ants at it on my drive on Saturday as it happens. Put some ant powder down to scare them off, and then brushed the sand back in next day. It was all still there in a pile on top of the paving. Time will tell how well this worked.

I’ve come to the conclusion that there is nothing that will stop ants, weeds etc from brick block paving.
Every house near me that has it has it has the same problem.
The only thing for it is to scrape the joints once a year and re-pack it - which works for a bit.
This year I did it and refilled with kiln dried sand than then very liberally used stone sealer soaking the joints. Helped by some very dry weather it has set like concrete but it won’t last and I’ll be doing it again next year…
I hate the stuff, worse idea ever.
