Why the foundation matters
A container home is strong and rigid, but it still needs firm, level support. A good foundation keeps the unit level so doors and windows close properly, lifts it clear of ground moisture, and ties it down against wind.
With every order we send a foundation drawing showing where the unit's base frame needs support. A local engineer or contractor turns it into a design for your soil and climate.
The three common options
| Foundation | How it works | Good for | Watch out for |
|---|---|---|---|
| Concrete piers | Concrete pads or columns under the corners and along the base frame | Most sites; slopes; keeping the ground mostly natural | Must be accurately levelled and placed to the drawing |
| Concrete slab | A continuous reinforced slab under the whole unit | Permanent homes; soft or uneven soil; multi-module homes | More concrete and time; drainage around the slab |
| Screw piles | Steel piles screwed into the ground by machine | Fast installation; remote sites; minimal excavation | Needs suitable soil and a specialist installer |
How to choose
- Soil: ask a local engineer to assess bearing capacity and frost depth where it applies.
- Slope: piers and screw piles handle slopes without large earthworks.
- Permanence: a slab suits a permanent home; piers and piles make relocation easier.
- Access: remote sites may favour screw piles over trucking in concrete.
- Local rules: some permits specify the foundation type for dwellings.
Preparing for delivery day
- Build the foundation to the approved design and let concrete cure fully.
- Check levels across all support points before the unit arrives.
- Bring power, water and drainage to the connection points shown on our drawing.
- Clear a route for the truck and a level, firm area for the crane.
- Plan tie-downs and the gap under the unit for ventilation and pipe access.
Multi-module and two-story homes
Two-bedroom, three-bedroom and two-story homes are set as separate modules. The foundation must hold each module at exactly the same height so they can be joined and sealed. Two-story homes need supports designed for the stacked load.
Send us your engineer's foundation design and we'll check it against the unit drawings before production.
