Coletrickle_780816 Jul 2024 08:12Hello,
We have now been living in our house for almost 2 years. We paved about 100 sqm (1,076 sq ft) with Kann Vios Aqua (stones 40x20 cm (16x8 inches) with 5 mm (0.2 inch) joints). The terrace is laid with Kann Vios slabs (80x40 cm (31x16 inches) and about 3 mm (0.1 inch) joints).
For sweeping, I used basalt fine crushed sand with a grain size of 0-2 mm (0-0.08 inch).
After any heavy rain, the sand washes out of the joints. So the entire paved area and terrace end up covered with small gravel.
This is extremely annoying, more than you can imagine. When sweeping, you always keep removing new stones from the joints. Weeds also begin to grow there, and moss forms nicely on the driveway (north side).
I have now taken the trouble to scrape out all the joints and refill them with sand. In addition, I have already treated about 60% of the driveway with MEM joint stabilizer. Specifically, I put the binder into a kind of ketchup bottle and let it run into the joints. At first impression, the joints do become firm. However, I must say I still have almost 1 liter (1 quart) left from the 5-liter (5.3 quart) canister, so it’s not a cheap solution.
On Amazon, some users mention that the effect fades relatively quickly and the joints return to normal, especially in long-term use. This might be because it is not a two-component (2K) liquid. I don’t want to waste money, so my question is: Is there a joint stabilizer or hardener that really bonds the joints long-term, is permeable to water, and prevents the joints from washing out during rain and similar conditions?
Thank you very much.

So far, the joints treated with the MEM joint hardener are still hard and firm. There is almost no moss or weeds growing in the joints so far, and keep in mind that this treated area is on the north side. This also includes the driveway, so it’s a surface that experiences load.
On the south side, at the terrace, there is currently only the basalt fine crushed sand. Here, the joints are full of moss and weeds. It’s remarkable, especially since basalt sand is more like crushed stone than actual sand. This was not the case with the previously used 1-3mm (0.04-0.12 inch) sand/gravel. So, in 2025 I plan to scrape out all the joints here as well and either re-sweep and treat with MEM or try something completely different, like NoGrow sand or 1K. I’m still not sure.
