FOOTING NOTES
• Support post footing depth equals 42 in. (1067 mm) less the depth of the
protective surfacing material. The post is 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 ®
posts are footed 12 in. (305 mm) deeper than the regular support
posts, and will be marked as such on the master footing diagram.
• Component footing depth equals 30 in. (762 mm) less the depth of the
protective surfacing material. The post is designed to have 12" (305 mm) in
concrete.
Example:
If 12 in. (305 mm) of wood mulch is used for surfacing, the footing
depth would be 18 in. (457 mm).
• Most support posts and component support legs will have either a factory-
applied sticker with line, or factory-applied mark designating protective surfacing
level on a clear and level installation site.
• If play structure is installed on uneven terrain, maintain support post mark
at protective surfacing level at lowest grade. Adjust other footings accordingly.
Support posts and all attaching decks and play components must be plumb and
level.
• Do not encase bottom of support post in concrete. Place post directly on
packed stone.
• The footings shown on Playworld Systems’ documentation are recommendations
based on historical performance in average soil conditions. Footing dimensions
may be modified 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.
• Base of footing must be below frost line.
• Assemble the entire structure before pouring concrete unless specifically
instructed to do so in the individual component installation instructions.
