Hello!
The new build is gradually taking shape. I have a quick question about the basement construction method:
Our main contractor is considering two well-established and reputable building companies. The basement will be constructed as a waterproof concrete structure ("white tank"), 30cm (12 inches) thick with 14cm (5.5 inches) perimeter insulation.
One company forms the basement onsite and then pours the concrete (waterproof concrete structure, "white tank").
The other supplies precast basement elements, which are then assembled and poured, with the joints later sealed.
Which option do you think is more practical, better, and safer?

The above describes a precast concrete basement made of WU concrete, not a white tank.
There is no better or worse; one builder prefers it one way, another builder the other. As long as the structural engineer’s requirements and the soil report’s results are met, there is no advantage or disadvantage to either system.
Best regards

There is no better or worse; some building contractors prefer one method, others another. As long as the structural engineer’s requirements and the soil survey results are met, neither system has advantages or disadvantages.
Best regardsJust to clarify: waterproof concrete (WU concrete) is used, and the entire construction complies with the criteria of a waterproof shell ("white tank") according to current/standard definitions.
Thank you for the clarification regarding the advantages and disadvantages. According to my general contractor, there really isn’t much difference between formwork and precast elements, which is why I wanted to ask if anyone here has more detailed information.
