Hello everyone,
We have built a house on a slope. Originally, a garage was planned next to it and was structurally designed accordingly. Due to the hillside location, the concrete slab of my workshop also serves as the garage floor slab (C25/30 WU concrete, no slope, 44m² (474 sq ft)). Attached is a picture. To the front and on the right side, the ground drops 3m (10 feet).
For cost reasons, we now want to build a carport, but we are having trouble choosing a suitable drivable floor covering. The area is not very large. According to the structural calculations, I cannot use pavers with the required base layers because they are too heavy. Additionally, they would not hold because there are no edging elements on the sides.
We are now thinking of using poured asphalt but have not yet been able to get prices. Our next idea was a stone carpet. However, a first quote was around 250 EUR per square meter (WTF?).
What options would you suggest? Maybe a concrete edging on the sides and then some kind of cement screed with a coating? Or a construction with adjustable pedestals and drivable panels? At the moment, we are a bit lost and want to avoid spending a fortune here.

We simply have crushed stone under the carport. ypg schrieb:

Oh dear... I would suggest keeping this matter in perspective. It’s just the parking space for the car.
Compare the costs with the flooring in the living room—that was definitely cheaper 😀
Crushed stone or gravel doesn’t cause worries about stains. If needed, just add a few shovels now and then, no ruts... and invest the money saved inside the house... or send it to me! How would you handle the slope and waterproofing of the concrete slab?

hampshire20 Apr 2021 14:55The concrete should not be affected by water. A slope is not strictly necessary. If the wind is unfavorable, there might occasionally be a small puddle.
The water does not, but the salt used for de-icing the roads breaks down the concrete within 2-3 years. We experienced this in our old apartment. The costs were enormous because even the pillars supporting the house were damaged at the base.
I would definitely protect the concrete, but unfortunately, I don't know what is needed for that.

This has to be done either by creating a slope or by applying a proper waterproofing layer. I don’t think there is a “nice” paint that provides this protection.
I actually find your idea with the gravel quite reasonable; there are special gravel grids made for this purpose. But again, the question remains about waterproofing and slope.

Reini123426 Apr 2021 08:41The topic is still relevant. Slope screed was recently offered to me for 40 EUR per square meter (approximately 3.7 USD per square foot), including grinding, priming, and an additional hardening agent. However, it would also need to be properly coated again. A sealant tends to peel off repeatedly.
What do you think about a mineral waterproofing layer, for example with a sealing slurry, followed by a type of protective roofing mat to protect the waterproofing, and then gravel? There would need to be an upstand at the edges.
