Location of city villa or single-family house on 500 m2 plot - rectangular

Oh, saw too late that already commented. It’s so confusing on the phone.

Are puddles actually bad?

Classic cement is a so-called hydraulic binder (ask Google ...), i.e. the cement hardens even in the presence of (a lot of) water, as long as not too much water was used in the production of the concrete. Wetting with water is even very positive when high ambient temperatures prevail, as otherwise cracks etc. can occur in the concrete.

So, new year new luck one thinks, but for me there’s first of all new trouble and new questions.

First of all, the announced additional expenses for the soil replacement are suddenly twice as high as previously assumed. The amount neither matches my calculation based on the estimate from the civil engineer (1000 EUR more) nor the total tonnage of the delivery notes attached to the delivery (should then be even more expensive).
Now I suspect errors in the allocation of the delivery notes for the fill sand. One delivery note has my name on it, the others have nothing.
I assume that the civil engineer just spoke of additional effort with me, and that’s why the general contractor charged me everything that went beyond the calculated effort for the neighbor behind. He himself will simply have received an invoice from the civil engineer, who ultimately doesn’t care for whom he used how much sand.
In any case, I have now asked for clarification.

Also, they actually start today (currently -4°C) to build the wall at the neighbor behind. At least the Poroton was delivered this morning:


Apparently there is a bonding system from Poroton (Dryfix) that also works down to -5°C.
But there is the problem that my water hose, which is connected to the neighbor’s outdoor faucet, is frozen. That means I don’t exactly know how they are getting water for the curing layer (with winter mortar) now.
I’m currently waiting for the phone to ring.

Also, I’m wondering how they are going to get the bitumen sheets onto the foundation slab now when everything is flooded? Or does that come afterwards? Doesn’t it have to go under the wall?

Best regards

For the outermost wall, I see enough space for the bitumen membrane. You definitely have a high-quality stone!

Oh, so they just lay the track under the outer wall, then first build up the wall and weld afterwards? ok, sounds somewhat plausible... Can you see the stone in the picture?!

Exactly, they lay the outermost course for the exterior wall, then a few stones are built on top. After that, the same process is done for the interior walls. Once all that is finished, the entire floor slab is extensively sealed and welded. It makes sense to first apply bitumen under the walls, otherwise every craftsman would walk over it multiple times and damage the layer. I can't identify the exact stone, but it is a Wienerberger. That alone already stands for very good quality ;-)
