We recommend using a spirit level to check for any unevenness across the installation area. If the slope exceeds 10mm or is uneven in multiple directions, adjustments may be needed before installation.

If your base has a slope greater than 10mm or is uneven in multiple directions, it may prevent proper installation and affect the alignment and operation of accessories. Side screens may not retract smoothly, and slatted walls may not stack evenly.

If your base is not level, we advise consulting a professional to correct any significant unevenness before installation. This will ensure the best fit and functionality for your pergola and accessories.

While minor variations can sometimes be accommodated, a base that exceeds the recommended slope may result in misalignment, reduced stability, and functional issues with accessories. In some cases, installation may not be possible without adjustments to the base.

A flat, level base with a slope of no more than 10mm in one direction ensures proper drainage, structural stability, and correct alignment of accessories. An uneven base can lead to installation difficulties and impact the functionality of side screens and slatted walls.

Slatted walls come in four sections that stack on top of each other. While every effort is made to ensure a precise fit, minor variations in alignment may occur, particularly if the base is not perfectly level.

Side screens require a level base for smooth operation. If the base is uneven, alignment cannot be guaranteed, and the screens may not function as intended.

If accessories are installed on an unsuitable base and this causes operational issues, it may affect warranty coverage. A properly prepared base is essential for long-term performance and durability.

Our pergolas are securely fixed to the ground using bolts through the post footplates. These fixings provide stability and safety and are neatly covered with post caps for a clean, polished finish. For Porcelain Flags: we recommend using a diamond drill bit to avoid cracking. For Decking: alternative fixings suitable for timber or composite decks.

For a smooth installation and optimal performance, it's essential to have a flat and level base. We recommend a slight slope of approximately 10 mm in one direction for proper drainage. Our recommended base options include smooth flag paving, timber or composite decking, or a concrete foundation. Please keep in mind that side screen alignment cannot be guaranteed on an uneven base. For detailed guidance on specific measurements, refer to our handy measuring guides. More info here.

Side screens require a level base for smooth operation. If the base is uneven or if your pergola is slightly out of square or the base isn't perfectly level, alignment cannot be guaranteed, and the screens may not function as intended. You can improve the movement by removing the internal foam strips within the mechanism to allow the side screens to move more freely. This provides additional tolerance.

We recommend 3m x 3m & 3m x 4m models – 2 bolts diagonal to one another per footplate are generally sufficient if installed on a solid base. We recommend 4m x 4m & 6m x 4m models – All 4 bolts on each footplate should be used for stability. If installing on porcelain, consider using 2 bolts per foot to reduce potential damage if the pergola is ever relocated.

Bolts should be finger-tight; tight enough to hold securely but not over-tightened, as this can cause operational issues.

Yes, grey silicone should be applied in every corner to seal gaps and enhance durability. This is recommended for all pergola models, not just the 6m x 4m Tora pergola.

If the trestle surface is smooth and clean, covering isn't essential. However, using protective covering is highly recommended to prevent scratches or damage to the powder coated surface of the aluminium.
