I'm widening my driveway and laying more block paving (standard 20

Something that has always annoyed me about the old block paving is
the ability of weeds to set up home in all the gaps.

I know that the recommended way of "setting" the blocks in to use
kiln dried sand but is there any reason not to use a sand/cement
mixture and deprive weeds of a chance to get rooted in the gaps?

This would also mean I could pressure wash the drive without
digging out all the sand.

Any comments?

try pavingexpert.com?

Thanks. I've just been looking at that link but it makes no mention of
sand/cement mixtures which, on reflection, don't really fit with the concept
of "flexibility" which is kind of inherent in any domestic blockpaving that
*isn't* laid on a solid base. Maybe I'll have to think again.


One problem with cement is the potential for staining but I guess it
depends what blocks you have.

Would a gallon of brick acid sloshed about deal with that?
