Don't you want a semi-permeable barrier? It stops weeds growing but
allows drainage.

If you put down an impermeable barrier you'll get puddles unless you
arrange enough slope to ensure rainwater can run off.

And both will in time get infested with weeds anyway..dust and water
collects, and seeds, and off go the weeds.

Only sure way to stop weeds is to use pathclear every year.
