Is joint sand suitable against weeds?

Hello everyone, does this No Grow stuff also affect the infiltration properties? Does whatever runs off in the joints now flow worse or not at all?

It is raining here right now: It is permeable like sand or soil, so it seeps away normally. By the way, this should also apply to the stuff with the binder.

Even at the risk of making myself unpopular, I make the following remark:

Instead of designing areas so that plants cannot grow there können, I would find it stylish to consider how to live well WITH plants :)

(and: yes, there are also places on the house I live in that I have "sealed" :cool:)

For permeable paving, one usually uses 1-3mm gravel; compared to that, this will definitely infiltrate much worse.

We have Sopro Solitär in our approximately 5mm wide joints for our ceramic tiles. It is a 1-component joint. Solid, water-permeable, and guaranteed weed-free

As far as I know, Dansand No Grow is exactly that. It doesn’t become rock hard, but it is broom-stable. However, there is apparently a more intense version with a binder.

My experiences with it are less good. The stuff forms a crust that becomes unsightly after about 6 months. It has not fully hardened for us. Hence the switch to Sopro.
