"Every couple of months" seems very frequent to me. I've got our
gravel pretty well dosed with sodium chlorate and it seems to be
fairly inhospitable to new growth. The trouble with using just
glyphosate is that it has virtually no residual effect so (as you
describe) isn't very long lasting.

Isn't Pathclear a season long weed suppressant?

It was in the good old days when it contained a potent and persistent
active ingredient called Simazine. These days it is pretty ineffectual
like and over priced knock down weedkiller. Again you can blame the EU.
