Hello everyone,

Construction has finally started at our site.
I would like to share my experiences, concerns, and questions about the house building process here to get feedback from experienced people.
So, it’s kind of a small building diary.

The earthworks have been completed with the delivery of 340 tons of sand for backfilling, and the trenches for the strip foundation have also been prepared.
The steel mesh for reinforcement is ready on site.

Now the date for the slab foundation is set.
Pipes for wastewater and the multi-utility connection need to be installed, the foundation grounding conductor has to be laid, a drainage membrane has to be placed, reinforcement tied, and formwork set up.
Is all of this achievable in one day, including the concrete delivery?

Before I provide more details, I’d like to hear your opinions.

Best regards
C

Where did you get that from?

You can even pour concrete in freezing conditions. It depends on many factors, so making a general statement is questionable.


Many things are possible! However, it is often recommended to avoid pouring concrete below 5°C (41°F) or during frost. The situation changes if the concrete is “prepared” for these conditions, for example by using additives or adjusting the mix/design of the concrete. But you cannot simply pour concrete in freezing conditions without precautions. If a foundation is poured 90% in one go and the rest follows later, I would definitely check whether the concrete is suitable for those low temperatures.

If you have enough time, you can't go wrong with your rule. It doesn’t cost anything at first. But if there are construction delays, it will probably become much more expensive than the modified concrete mix, concrete temperature, and altered curing process.

By 90%, I mean the foundation. See the pictures.
Whether this is a problem is currently being checked by an independent expert.

The foundation slab was poured at around 0°C (32°F). It included special additives and, according to the expert, looks proper. The strip footings were poured at temperatures above +5°C (41°F).

Don't you have an architect or site manager overseeing this mess?
You don't seem to be very familiar with construction.

How did you contract the building work?

The foundation, as it was constructed, does not serve a structural function but only acts as frost protection. In this context, the joint is not significant either. However, you should consider consulting a qualified construction supervisor.
