Hello,
I have an elevated driveway where I’m dealing with a minor weed problem.
The gaps between the paving stones are a few centimeters wide (see photos).
When I purchased the property, these joints were filled.
However, the previous owner had to have them reopened by the city because the water was draining into the sewer system.
The water must, of course, infiltrate on the property itself.
The area is about 60m² (650 sq ft).
There is standard gravel beneath the paving stones.
Does anyone have experience with how to solve this weed issue?
Jointing sand? No-grow additive?
Basalt gravel 1–3mm (0.04–0.12 inches)?
Weed membrane and re-laying the pavers?
Blowing out everything between the joints?

Has the requirement been lowered or is there actual contamination in the production? The latter can’t really be confirmed by the commission; that would have to be demonstrated by the production itself.
That seems too uncertain to me. Considering what is already inside clothes labeled with "men’s colors" and cosmetics...
I’d rather scrape out the joints.
