🧱 Why Reinforcement Is Needed
Hansø Pro+ Pergolas are wind-rated structures (up to 165 mph gusts). Pavers alone cannot resist vertical or uplift forces — hidden concrete footers beneath each post are required.
⚙️ Recommended Method: Flush Concrete Footers
Use when installing on interlocking, brick, or stone pavers.
Steps:
Mark Post Locations
Use your Pro+ model’s Outer-to-Outer Post dimension for layout.
Remove Pavers at Post Spots
Cut or lift pavers where each post will sit.
Excavate for Footers
Hole size: 400 × 400 × 400 mm (16″ × 16″ × 16″).
Compact sub-base to eliminate shifting.
Pour Concrete
Use 25 MPa (3,600 PSI) concrete mix with small aggregate.
Level to match the paver height.
Allow 72 Hours to Cure.
Anchor Pergola Baseplates
Once cured, install M12 expansion bolts through each baseplate.
Refill edges with joint sand or grout to finish.
⚠️ Important Notes
Never drill anchors into pavers only.
Avoid mortar-set pavers with hollow cavities.
Ensure downspout drainage doesn’t terminate between paver seams.
💡 Tip: Add a thin silicone bead under baseplates to prevent water ingress under pavers.
