SURFACE MOUNT SYSTEM
1.5.1
What is a Surface Mount system?
Surface Mount means that the vertical posts for a pergola are secured to the top of a concrete footings, concrete pad, or deck
cross-brace beams using Floor Anchor Brackets. You may bolt the floor anchor brackets directly on top of a concrete pad or on
top of a footing. If bolting on top of a deck, you must add cross-brace beams under the deck boards to fully support the weight of
the pergola.
For concrete footings, the required depth is determined by the maximum depth of the frost line for a particular area. The
diameter of the footing is determined by the weight that each footing is subjected to by the pergola structure. If you choose to
use concrete footings or to add this pergola on top of an existing wooden deck, consult your local building permit office to
determine the required footing depth and diameter and the cross-brace beam requirements. If you fail to follow local officials’
guidelines, permanent damage to the Pergola structure or the deck structure can render them unsafe for use.
