500mm3 CONCRETE PAD
Manhattan Pergolas require a flat surface to stand on
If there is any doubt about the stability of the surface your pergola will sit on, we recommend creating a 500m3 concrete pad for each of the legs to sit on.
TARMAC | SLABS
We recommend using 150mm resin fix raw bolts to secure the structure
Where the solid surface is less than 150mm thick, we recommend lifting slab etc, creating a concrete pad and replacing before fixing.
Pergola feet can be fixed directly to level wood or composite decking that is in good condition.
Where there is doubt, a patress can be used to increase stability. Again, a concrete pad can be created with decking on top.
TURF | SOIL
A 500mm3 concrete pad should be created for each leg where pergolas will be situated on grass or loose earth.
