Concrete is poured in a controlled sequence, vibrated as required, and leveled to tight tolerances. For modular construction, slab flatness is not a luxury — it is a requirement. Protect the slab, follow curing guidance, and avoid early overloads.

Start з accurate setting‑out і a base that can be compacted і leveled. At this stage you also lock the locations for:

Is an insulated Swedish slab always better than a traditional strip foundation?

Not always. Soil conditions, groundwater, structural loads, and local regulations matter. But for energy‑efficient buildings, USS can simplify thermal bridge control and provide a comfortable, high‑performance base.

Can USS be used with modular homes?

Yes. In fact, a flat, insulated slab with pre‑planned penetrations is one of the best foundations for modular construction, reducing on‑site uncertainty and speeding up installation.

Do you always need underfloor heating in the slab?

No. Many Passive House projects heat via ventilation or compact hydronic systems. Underfloor heating is a comfort choice and can be efficient when designed for low temperatures.
