ᐅ Is water seeping up through the paving?

Our plot is located on a gentle slope on the inside of a bend. Since we did not align with the highest point of the former construction road, our plot lies partly slightly below the level of the road. We have now noticed that during the heavy rains of the last few weeks, water is pushing up from beneath the paving, both partly in our driveway and on the public road. This water has, of course, now frozen.

We have two drainage channels that normally collect and divert this water. However, on public land there is a drainage grate positioned too high up the slope and another one too far beyond the curve to effectively collect the water. Is this normal, or was there possibly poor workmanship during the road construction?

If you expect helpful answers, it is advisable to describe the problem more clearly.

Do you have two drainage channels on your property, one on each side of the driveway? Or where exactly are the channels located? And do they have an insufficient slope, causing water to remain standing in the channel?
You are responsible for the drainage on your property.
Or what exactly is the issue?

I don’t fully understand the part about the public road. It is probably paved and therefore impermeable to water, right?

Regarding your pavement... if the subsoil has poor drainage, water will remain standing in the gravel for some time. If there is a depression in the surface and there is heavy rainfall, water can collect there and cause upward pressure. Water can also seep sideways along the slope within the gravel. A channel can help alleviate the symptom, but it does not address the underlying problem. If the pavement base and joints are saturated with water and temperatures drop (as they are currently), this can lead to frost damage.

I will attach a few pictures. My explanation might not be very clear for someone unfamiliar with the situation.

First, the view looking out from our driveway:

Then the view uphill:

And finally, the view downhill:


You can see (or at least notice) that water is pressing up from underneath the paving. In all the other curves in the building area, where I took the two photos on the street, there is an additional drain in the central gutter to channel water away. But in this particular curve, there are only the drains I have marked. The one opposite the driveway feels like it is positioned too high on the slope. The second one, further down the road, is currently not reached by ice or water at all.

In my driveway, water is pushing up through the paving where it has now frozen. Normally, it would flow into the drainage channels, but there was probably too much water and temperatures dropped too quickly, which is why ice has formed there now.

Does this seem "normal" to you, or should I consider raising the issue with the local authorities?

It looks on the phone like there is a dip in your driveway. So no slope towards the drains.
==> Incorrectly constructed driveway.

But the photo could also be misleading.

I found another picture of the driveway taken from above. The red arrows point to the drainage channels. The slope ends approximately at the red arrows. On the left is the channel in front of the garage; the garage itself is dry, and the water in the channel is also standing still.
When it rains, the water does try to flow in the right direction. The water visible here seems to come from below because it remains for quite a while after rainfall or is pushed up from underneath. As you can see, the street is wet even though it is no longer raining, and the upper parts (uphill) have already dried or are drier.
