OT: Why Sand Between Paving Stones?

 

Somebody in this august body must know.

Seems like there's gotta be a reason....

Locks the pavers together...
The small grains of sand fills in the joints and the fiction keeps the
pavers from moving...

     Donald is the only one who has it right so far.  I like to use sand mix
myself.  Just sweep it into place like ordinary sand...but then it REALLY locks
them together.

It helps keep the seeds form growing weeds bwteen them. No other
reason.

 

Most pavestones have little spacing bumps on the sides between them.
The sand does nothing except slow down seeds settling between them and
growing weeds.

Once the sand gets washed out or erodes the weeds start growing and
push them apart. This is why you have to sweep more sand in every few
years. Many large pave stones areas do not use sand at all if there
are no grass yards nearby.
