ᐅ Concrete slab with polymer fibers and reduced reinforcement steel

Hello everyone,
Let me briefly introduce myself, as I’m new here.
My wife and I decided at the beginning of 2023 to build a house, and we are working with the companies Danwood and Glatthaar to construct a small one-and-a-half-story detached house.
We recently had the site kickoff meeting with Glatthaar, which went well – we’re excited that the project is finally starting.
Afterwards, I was told on the phone that our house is suitable for a "hybrid slab," and Glatthaar would like to use this to improve their environmental balance.
Today, I received a letter about this. Unfortunately, it doesn’t contain any concrete information, such as how much steel will be reduced or the amount of plastic fibers added to the slab. I have no clue.
So my question is: is this a good solution? Of course, I’m skeptical – like many others building a house, we expect to live in it for a long time. I don’t want the foundation slab to cause problems later on.
Here is a quote from Glatthaar’s letter:
They plan to use "a combination of reinforcing steel and MasterFiber polymer fibers." Furthermore, "the addition of polymer fibers is approved by the DIBt (German Institute for Structural Engineering)."
What do you think? Is this a viable method, or is it better to avoid it?
Best regards and thanks in advance for all your answers!

No idea!
Which model are you building from Danwood? I like their houses and would have liked to build with them – but in the end, they were too expensive for us. Isn't Danwood considered one of the more affordable options on the market?

I find it surprising that no one has brought up the issue of microplastics in drinking water yet. After all, these polymer fibers are essentially the same thing. When structures like concrete buildings are demolished, a large amount of these fibers is released into the environment – whether we are alive or not is irrelevant to the ecosystem. It’s quite alarming that this is supposed to improve the ecological footprint. It took a long time to change the approach with asbestos as well. Of course, steel requires a lot of energy to produce but can be recycled without any problems. Thinking about our old house and the slab we demolished: the concrete was crushed in a breaker and used as fill material, and I took the steel to the scrap yard. Nothing was left over.
Try calling a waste disposal company and tell them you have a polymer fiber-reinforced foundation slab to dispose of. They’ll roll out the red carpet for you. We had a similar issue with bricks filled with mineral wool – considered hazardous waste by the disposal company because they fall into different waste categories and are difficult to separate. That’s why we ultimately chose perlite as fill material since it can be disposed of with the bricks in the same waste category without any additional separation required. Even though I’m far from being an eco-activist or climate extremist, I see it similarly. All this polymer and microplastic pollution should be much more restricted and possibly banned.

I don’t have precise numbers or data, but from what I remember during our house-building research phase, Danwood was among the best in terms of price/performance ratio—especially if you want a fully turnkey build.
What we were told directly by Danwood were the additional costs that we would face.
At that point, you’re already out of the ‘budget’ category.
Danwood basically delivers the house only.
Everything else—including architectural services and so on—comes at an extra cost.
What convinced us was that we heard many positive reviews about Danwood from various sources.

We were able to attend an appointment on site, and I had the Brave custom downsized and recalculated.
Including additional services, the price was beyond our budget.

You can’t reinforce anything with them.https://www.instagram.com/11antgmxde/

xMisterDx29 Feb 2024 12:56So plastic suddenly becomes bad in this context? For a foundation slab that stays in place for 50, 70, maybe 100 years? I would definitely expect those who criticize this to only buy products at the fresh food counter in the supermarket and avoid any products in plastic packaging or plastic bottles...
By the way, what about multilayer pipes for drinking water and underfloor heating? Did you use copper there? Because plastic is bad...
