Only the screed is broken or worse?

Bowling per se does not damage the screed; however, it could be that cracks have formed in the process. These cracks, if present, must then be assessed by a professional on site after the tiles are removed. It could very well be that the screed does not need to be removed at all... although personally, I would still do the work to install underfloor heating afterward.

As for the costs of removal: ~40€ per cubic meter of debris and 15-30 minutes per square meter (depending on thickness, work equipment, distance between the container and the house, etc.) multiplied by an hourly rate X.

The cupping itself does not damage the screed; however, it is possible that cracks have formed as a result. Any such cracks, if present, must then be assessed by a professional on site after the tiles have been removed. It could well be that the screed does not need to be removed at all... although personally I would still do the work in order to install underfloor heating afterwards.

Just an idea: If you already recommend underfloor heating, it should be noted that the floor construction will then be higher. Or am I mistaken? The OP should keep that in mind and measure and check the current room height.

The de-arching itself does not harm the screed; however, it could be that cracks have formed in the process. These cracks, if present, must then be assessed by a professional on site after the tiles are removed. It could well be that the screed does not need to be taken out at all... although personally, I would still do the work in order to install underfloor heating afterward.

As for the costs of removal: ~40€ per cubic meter of debris and 15-30 minutes per square meter (depending on thickness, work equipment, distance between container and house, etc.) multiplied by an hourly rate X.

If then the screed is completely removed, look at the positive side: underfloor heating, yippee!

Thanks for the cost breakdown. Roughly calculated for 140 sqm, I come to 3,500 to 4,000 EUR at 40 EUR hourly wage. New underfloor heating and screed installation then are 10,000 EUR, so all in all about 14,000 EUR

Just as an idea: If you already recommend underfloor heating, one should note that the floor structure will then be higher. Or am I mistaken? The OP should keep that in mind and check the current room height.

Room height is 2.60 or 2.70. Should fit unless a basketball team comes to visit

Just do it yourself. The numbers from are also way too generous. Not too long ago, one afternoon, I knocked out the screed from an entire upper floor with another guy. It wasn't a huge place, I'd guess about 60-70 m². By the way, without any electrical help, just with a sledgehammer, a crowbar, and a shovel. Construction debris doesn't cost 50€ / m³ either; you just have to make sure that only the debris actually goes in.

Thank you apokolok. I am thinking the same. What I do not want to do myself is to lay the screed again, especially the underfloor heating. You can tell yourself that if there are mistakes, it results in a lot of effort.

Yes, screed is a professional matter. Installing underfloor heating itself is not the problem; the planning just has to be right. Basically, rough work like demolition, chasing walls, etc. are good opportunities to save some money through own work. You can't make many mistakes, and craftsmen naturally are not eager to do it because it is physically demanding work. Once you've done it, it's not a big deal, but nobody wants to do it every day.
