Hello everyone,
We are currently working on our paving.
The paving stones are from Kann Bausysteme and are called Parchetto.
We have the following issue. See pictures:
Is this type of installation acceptable? When the stones were laid, we were not at home but at work. Should the paver have been more careful?
Because the dark stones are placed directly next to the light ones, it looks very odd.
When we looked at the samples at the store before ordering, it was not clear that the color variations in this paving would be so pronounced.
The laying pattern looks like this:
We actually like this part. We are desperate and don’t know what to do. We don’t like how it looks at all.
Best regards
Koempy

And this is what annoys me about building: if it had really been a professional company, they should have used their brains before starting the installation. I would insist on a proper repair without any ifs or buts... but I wouldn’t be surprised if you still had to pay for it.
So, we have received the initial response from Kann Bausysteme:
I also found the following text on the OBI website and the Kann website, which is used as a product description for the paving stones:
We are now divided.
Since Kann Bausysteme quickly offered a 50% discount to accommodate us, I think something might be wrong there.
But there is also the risk of pushing too hard if we insist on an on-site appointment and they withdraw the offer.
What bothers me is that they advertise the stones as being easily installable by inexperienced workers, thanks to the almost ready-to-lay combination.
We are now unsure whether to accept the offer and manually swap stones afterward, or what else we should request. Our paver advises us to definitely continue insisting on an on-site appointment.

After reviewing the photos, it appears that, among other things, packages from two different batches or production plants were delivered. This is the only way to explain the color variations.
Basically, we manufacture the same products at different production sites in Germany. For the production of our products, we use natural raw materials such as sand, gravel, crushed stone, cement, water, etc. These have a significant influence on the color and surface of our products. Since the raw materials used are natural products and subject to regional quality fluctuations, color variations in the finished products cannot be technically avoided despite our careful and extensive quality controls.
As all concrete product manufacturers are equally affected by this, the relevant standards for concrete pavers (DIN EN 1338 – concrete paving stones) include the following note:
“Variations in color intensity and surface texture of paving stones can be caused by unavoidable differences in coloring, fluctuations in the properties of the raw materials, and curing, and are not considered significant.”
Furthermore, weathering and mechanical stress over time lead to changes in color and surface texture of the concrete products. These existing color variations partially even out noticeably over time.
Regarding photos and product images, we also explicitly point out in all our documents that various factors such as camera angles, lighting, sunlight, shadows, surroundings, monitor settings, etc., can strongly influence the perceived color and surface effect.

Since the product as a whole does not meet your expectations, we are willing, as a gesture of goodwill and without admitting any legal obligation, to offer you a one-time discount of 50% on the entire area. We would transfer this amount to you upon presentation of the relevant bank details and original invoice.
I also found the following text on the OBI website and the Kann website, which is used as a product description for the paving stones:
The new trendy Parchetto design paver brings the charm of lively architecture into your home with its two naturally appearing, light color shades. Its functionality and straightforward design create a stylish and modern ambiance in all outdoor areas around the house – on terraces, walkways, and even frequently used driveways. The nine different stone formats of the Parchetto paver create a varied surface pattern and are almost ready for laying in the pallet arrangement. This makes installation quick and easy even for inexperienced DIYers. Each delivery unit already contains, layer by layer, the correct number of nine individual stone sizes (40 x 10 cm x 7.5 cm, 30 x 10 cm x 7.5 cm, 20 x 10 cm x 7.5 cm, 40 x 12 cm x 7.5 cm, 30 x 12 cm x 7.5 cm, 20 x 12 cm x 7.5 cm, 40 x 18 cm x 7.5 cm, 30 x 18 cm x 7.5 cm, 20 x 18 cm x 7.5 cm), each covering an area of 0.96 m² (10.3 ft²).
We are now divided.

You might later mention that you don’t like the color gradient, but at the same time, you will have to acknowledge the provider’s goodwill. With this discount, they are primarily protecting their reputation.

Take the discount and pass it on to your paver; it doesn’t get any better than that! Or are you aiming to be right at any cost? This recklessness could easily backfire; the manufacturer explicitly points out the variation in color.
Personally, I don’t really like these concrete pavers in general, but I agree with Yvonne that the way they were laid—perhaps unintentionally—stands out from the rest of the pavement. Moreover, it will change over time.

I have also laid these colorful stones with my husband. The color gradients are always arranged in sequence on the pallet, so first one color, then a mixed transition, and then the next color. You need to line up a large pile of stones next to each other and mix the stones well. While laying them, you have to consider for each stone which shade might fit best and constantly look at the overall color gradient. Since I’ve done this before, I wouldn’t let a tradesperson do it without supervision. I would be worried that it wouldn’t look good. I can’t imagine that every tradesperson pays that much attention to detail.
Best regards,
Sabine

HilfeHilfe20 Jun 2016 13:38We had similar stones and a similar issue when the darker tones occasionally matched up. The paver swapped a few stones around. After 2 years, it no longer bothers us, and we don't notice it either. Friends never noticed it. I also think the darker tones have faded quite well.
Yes, we are also considering simply hiring the paver to use tongs to pick up the stones and swap them around. Although that would mean two days of work, it could probably be covered by the money we received back. Then it probably wouldn’t look as bad anymore.
I have now received the phone number of the field representative from the local supplier and spoke with him. I would like to have him take a look and hear what he has to say.
We are not opposed to taking the money. If we can break even somehow and it still looks reasonably acceptable in the end, we would be satisfied. But at the moment, we are not.
It is a difficult situation. So far, we still really like the sizes of the stones.
