FOOTING NOTES (IN GROUND)
• Support post footing depth equals 42 in. (1067 mm) minus the depth of the
protective surfacing material. The posts are designed to have 24" (610 mm) in
concrete.
Example:
If 12 in. (305 mm) of wood mulch is used for surfacing, the footing
depth would be 30 in. (762 mm).
• GroundZerO
®
support post footing depth equals 54 in. (1372 mm) minus the
depth of the protective surfacing material. The posts are designed to have 36"
(914 mm) in concrete.
Example:
If 12 in. (305 mm) of wood mulch is used for surfacing, the footing
depth would be 42 in. (1067 mm).
• Most support posts and component support legs will have either a factory-applied
sticker with a line, or factory-applied mark designating the level of protective
surfacing on a clear and level installation site. The footing depth measurements
are based on this line/mark.
• If the play equipment is installed on uneven terrain, maintain support post mark
for the protective surfacing level at the lowest grade. Adjust other footings
accordingly. Support posts and all attaching decks and play components must
be plumb and level.
• Do not encase the bottom of the support post in concrete. Place the post directly
on packed stone or other porous material.
• The footings shown on Playworld Systems’ documentation are recommendations
based on historical performance in average soil conditions. Footing dimensions
may be modifi ed by the owner based on actual soil conditions.
For example:
- If local soil is loose or unstable, a larger footing may be required.
- If local soil is considered stable, such as bedrock, clay or hard packed earth, a
smaller footing may be used. Before changing footing dimensions, we strongly
recommend that the footings be reviewed and approved by a registered
engineer.
• The base of the footing must be below the frost line.
• Assemble the entire structure before pouring concrete unless specifi cally
instructed to do so in the installation instructions.
