ᐅ Uneven and loose paving – what can help?

Hello everyone,
we recently had our driveway paved with natural stones. Unfortunately, I am not satisfied with the result. Many stones are still loose, and the surface is extremely uneven. We had a pathway paved with the same stones about 2 years ago, and that one turned out perfect.

I have already spoken with the builders, and we will find some kind of agreement. However, they are not professional landscapers but rather a general construction team that handles various tasks. (After 4 companies didn’t even submit a quote, we were just glad they finally agreed to do it.)

The main question is: How can I make the already laid stones as level and firm as possible? We are now trying to get a heavy (700 kg (1,540 lbs)) vibrating plate, as the previous one was too weak. Will that be enough to level everything properly?

According to Rsto, this is a BK 7 classification, and 38cm (15 inches) of frost protection (crushed stone base layer) is required in a compacted state. Natural stones can be laid in a 0-5mm (0-0.2 inch) split sand mixture or a regular sand bedding, unlike concrete pavers, which are installed in a 3-5cm (1-2 inch) thick split bedding with a 2-5mm (0.08-0.2 inch) aggregate. If the paving shows a variation of up to 2cm (0.8 inch) over a length of 4 meters (13 feet), this is acceptable. Any greater difference is not. See DIN EN 18317:2006-10, section 3.3.1.5 on flatness, as well as DIN EN 18202. With your specifications, you will not achieve a level surface.
Best regards

The vibrating of the large stones made a difference. It’s not a perfectly smooth surface, but we’re not that picky. Fits the village: bumpy, old, and chaotic.

The smaller area will be addressed later.

This is how it looks now. Visually, I find it quite charming. Walking on it is so-so – but we’re getting used to it. Basically, we’ve kept out the fancy ladies with high heels.

It looks really old.
Clearing snow on this kind of paving is no fun. You always get stuck with the shovel.

Clearing snow? I just say climate change.
