Ground Screws vs Concrete Foundation: What Swedish Homeowners Need to Know

When building an extension, garage, or cabin in Sweden, one of the first decisions is the foundation type. Traditional concrete slab or modern ground screws (markskruvar)?

Ground Screws (Skruvgrund)

Ground screws are steel helical piers screwed directly into the ground. Benefits:

Fast installation: A typical foundation can be done in 1-2 days
No waiting time: No concrete curing needed
Eco-friendly: No concrete production needed
Reversible: Can be removed and reused
Works in frost-prone soil: Deep enough to avoid frost heave

Concrete Slab (Betongplatta)

The traditional choice, but:

Takes 7-14 days to cure
Higher carbon footprint
Permanent (cannot be undone)
Requires excavation

Cost Comparison (Sweden 2026)

Foundation Type	Typical Cost
Ground screws (30m²)	30,000–50,000 SEK
Concrete slab (30m²)	80,000–150,000 SEK
