A stable foundation is decisive for the lifespan of the house. An incorrect foundation can lead to moisture, settling and cracks that become expensive to fix afterwards. SFM Entreprenad builds foundations for new builds, extensions and ancillary buildings with careful checking of the ground, drainage and insulation before casting.
Foundation types we build
- Slab on ground – the most common foundation for new construction
- Foundation walls and edge elements
- Pier foundations for attefall houses, garages and sheds
- Ground insulation and capillary-breaking layers that keep the foundation dry
Proper preparation makes for a secure foundation
A durable foundation begins long before the casting. We ensure load-bearing and compacted ground, drainage and a capillary-breaking layer as well as correct insulation – so that the foundation stands firm and stays dry year after year. We handle the entire chain from excavation to finished foundation.
What affects the price of a foundation?
The cost is governed by the foundation type, the size of the house, the ground conditions and how much excavation and drainage is needed. After a site visit we provide a fixed quote with no hidden costs.

Frequently asked questions about foundations
Which type of foundation suits my house best? +
The choice between slab on ground, crawl space or piers depends on the ground conditions, the design of the house and the groundwater level. Slab on ground is the most common for new construction, while piers often suit attefall houses and ancillary buildings. We give you a recommendation after a site visit.
What does a foundation cost? +
The price depends on the foundation type, the size of the house, the nature of the ground and how much excavation and drainage is required. We always provide a fixed quote after a site visit so that you know the total cost in advance.
Do you build foundations for attefall houses and ancillary buildings? +
Yes. We build pier and slab foundations for attefall houses, garages, sheds and other ancillary buildings – adapted to the building permit and ground conditions.
Do you collaborate with the house supplier? +
Absolutely. We are happy to coordinate directly with your house supplier or building contractor so that the foundation is correctly dimensioned, drained and finished in time for the house assembly.
