High curb and concrete, but which one is recommended?

Um, but the calculation method is not quite right. You need at least 40-50 bags of concrete screed. Cement, as mentioned, only about 12-13 bags plus the gravel. These are all quantities that are better not to get yourself at the hardware store; for such things, there are building material dealers. A normal car is quickly overloaded with a few bags of concrete, you will drive yourself silly. Where do you buy the curbstones and the slabs? Doesn't the store also have gravel and cement? Getting everything from one truck does make sense, the trip costs money too.

No idea which concrete exactly. I just asked how much he charges for the bag of concrete, then came the price. But I also think it is garden construction concrete, which costs more at Bauhaus etc. than this concrete screed. What is the difference?

So curbstones, slabs, so everything, I buy from the building materials dealer. I don't know if they also have gravel/cement. Probably, but I didn't ask. Delivery is free of charge.

Hi, so.
Here is my calculation:

Bauhaus 40 times 40kg concrete bags equals 131€ or 152€ from the building materials dealer

Mixing yourself:
16 bags of cement = 400kg = 41.44€
1m³ gravel 0/16 = 1600kg = 44.36€
Big Bag = up to 1500kg = 21.00€
Delivery = 117.00€

That would be a total of about 224€ when mixing yourself 1:4 (from the gravel everything from the [Erdenwerk])

Now I have to quickly follow up tomorrow whether my building materials dealer also delivers gravel and cement, then it might really be a bit cheaper.

Regarding the question from earlier, what is the difference between screed concrete and [GalabauBeton]?

Yes, of course I didn't know the delivery costs ^^ Ask the building material supplier, he definitely also has gravel and cement. If the ready-mix concrete is cheaper, buy it there anyway and not at Bauhaus, otherwise you'll be busy driving for half a day (depending on the distance).

ok, thank you very much. You have helped me a lot so far!!!
