Building a pergola starts with choosing the right foundation. The correct post support can significantly improve stability, durability and overall appearance.
So what is the best post support for a pergola?
The answer depends on where you’re building it.
Pergolas on Patios and Concrete Bases
If your pergola will be installed on:
- Existing concrete
- Paving slabs
- Patios
- Reinforced bases
Bolt down post supports are usually the preferred solution.
Advantages
- Fast installation
- No excavation required
- Clean, professional appearance
- Easy replacement if needed
Pergolas Built Directly on Soil
For freestanding pergolas installed in gardens or lawns, concrete-in supports often provide the strongest foundation.
Advantages
- Exceptional stability
- Excellent resistance to movement
- Suitable for larger structures
- Ideal for exposed locations
Galvanised or Stainless Steel?
Galvanised Supports
Suitable for most residential pergolas and outdoor projects.
Stainless Steel Supports
Recommended for coastal areas, luxury landscaping projects and locations exposed to higher levels of moisture.
Our Recommendation
For patios and paved areas, choose bolt down supports.
For new garden installations on soil, choose concrete-in supports.
