ᐅ Is Jointing Sand Effective Against Weeds?

Good evening,
after extensive paving work and laying of stone slabs, we would like to fill the remaining small joints with a suitable material to minimize weed growth. We found online that there is a so-called "No Grow" joint filler sand that is supposed to prevent weeds from growing.

Therefore the question: Is something like this recommended? Has anyone here possibly had experience with it? Or are there better solutions?

Hello everyone, does this no-grow stuff also affect the infiltration properties? Does water now drain worse or not at all through the joints?

It is currently raining here: The material is permeable like sand or soil, so the water soaks in normally.
This should also apply to the material with the binder.

Even at the risk of being unpopular, I would like to make the following comment:

Instead of designing areas so that plants cannot grow there können, I think it would be nicer to consider how to live well WITH plants 🙂

(and: yes, there are also spots at the house where I live that I have "sealed" :cool 🙂

For permeable pavers, gravel with grain size of 1-3mm (0.04-0.12 inches) is usually used; compared to that, drainage will definitely be much worse.

We used Sopro Solitär in our grout lines, which are about 5mm (0.2 inches) wide, for our ceramic tiles. It is a single-component grout. It is firm, water-permeable, and guarantees to prevent weed growth.

As far as I know, Dansand No Grow is exactly that.
It doesn’t harden completely but is broom-stable.

There seems to be a stronger version with a binder.

My experience with it is less positive. The material forms a crust that becomes unattractive after about 6 months. It never fully hardened for us. That’s why we switched to Sopro.
