I currently have a company at home installing a new motorized Hörmann door (2375 mm wide) in the garage. Unfortunately, the concrete floor slopes 34mm from one edge of the door to the other. I believe the floor was poured in the early seventies. The door has been installed horizontally with a level as it should be, so now I need tips on how to seal between the door and the floor by raising the floor a bit on one side.
Self-leveling compound, some type of cement, leveling compound, or something else? What do you recommend? (There is a car in the garage that is not driven in the winter, in case this affects anything. Mainly thinking about the fact that it doesn't use studded tires, etc.)
The upper image shows how far up the track is from the floor to keep the door horizontally mounted. The lower image shows how the track on the other side is mounted.
I would probably have tried renting a concrete grinder and removed from the high side unless the high-mounted side makes it so that the gate can't go down any further.
You should be able to cast that with almost anything really; fine concrete probably works well. Make the curb with a slope on both sides so it's easier to drive over. It might be difficult to get the concrete to adhere to the slab in a watertight and proper way. Some type of primer is probably appropriate.
The simplest and cheapest way is to buy a heavy rubber mat about 5 mm thick, close the gate to about 3 mm open where it meets the floor, and screw it to the lower part of the gate with many screws and washers (about 10 cm between screws), so it becomes tight. Perhaps not so aesthetic but functional and practical.
Is it possible to replace the rubber strip at the bottom of the door with one that fits the floor or one that is higher and softer, thereby molding to the floor?

Thanks for the reply. Could work, but the door is where it is now and 34mm is quite a lot to remove anyway. Hope to be able to add some material on the other side instead.
Thanks for the response. It might work, but the door is fixed in place now and 34mm is quite a lot to remove anyway. Hopefully, I can add some material on the other side instead.
True, didn't the ones who installed the door have any idea/product for this?
Is it possible to replace the rubber seal at the bottom of the door with one that fits the floor or one that is higher and softer and thus shapes itself to the floor?
You should be able to cast that with almost anything, really, fine concrete will likely work well. Make the rise with a slope on both sides so it’s easier to drive over. It might be difficult to get the concrete to adhere in a waterproof and efficient way to the slab. Some type of primer is probably advisable.
This answer sounds like a good permanent solution. I'm considering casting a meter or more inside the garage if I'm casting anyway. The question is whether it's possible to cast with fine concrete as thin as it will be at its thinnest? It will go from 0 mm thin to 34 mm thick. I believe the last bag of fine concrete I used stated 30 mm. If fine concrete doesn't work, what should I use then?
You can indeed order the gate with a section customized for this as well, I believe, read about it when I was going to order mine, even if it feels like going overboard.
But perhaps the installer hasn't really done their job if this wasn't discovered during the measurement before ordering?
Simplest and cheapest, buy a thick rubber mat about 5 mm thick, close the gate to about 3 mm open where it lies against the floor, and fasten it to the bottom of the gate with many screws and washers (about 10 cm between screws), then it will be sealed. Maybe not so aesthetic but functional and practical.
I have almost done so for the moment. Have taken the old gate's rubber strip and clamped it between the new rubber strip and the floor. Not pretty, almost functional but free.
Is it possible to replace the rubber strip at the bottom of the door with one that fits the floor better or is higher and softer and thus conforms to the floor?
The rubber strip is quite substantial in its original form as it seems to accommodate around a couple of centimeters. I asked the door installer about another strip, but his suggestion was to level the floor in some way. Unfortunately, he was not an expert on concrete floors. He knew as much about concrete floors as the average person, as he put it.
