Simple
Direct Embedment
The most common method for installing a concrete pole is by
direct embedment. The pole is placed into an augered hole on a
granular base and back filled with native or selective soil.
Advantages of direct embedment over base mounting:
- Faster installation, more poles per work crew per day
- Independence from foundation contractors schedule
- Extra pole length for embedment is less costly than separate
foundation
- Structural continuity between pole and foundation
- Instant completion of ground around pole
- Clean, neat final appearance in sod, concrete or asphalt
Quick Installation Method
1. Pre-wire the pole using the pull string provided.
2. Install fixtures.
3. Auger hole. Typical embedment is 10% of pole length plus two
feet or as per project specifications. Hole should be 10"
larger than the pole base and deep enough to for min. 4"
granular base.
4. Attach a nylon sling approximately 1/4 of pole length from
the tip of the pole and lift the pole into a vertical position.
5. Lower the pole into the hole and rest on the granular base.
6. Plumb pole and backfill with native or select granular material
in shallow lifts.
Backfill
recommendations
Good
Soil Conditions
In native sand & gravel, silty sand and gravel, and well compacted
granular fill, the excavated material can be used as backfill
Acceptable
Soil Conditions
In moist silty sands, and hard to medium soft clays select granular
backfill should be used (i.e. sand or screenings).
Poor
Soil Conditions
In loose wet silt, soft clay, loose fill, organic soils and high
groundwater conditions consult your project engineer.
