Direct Burial Light Pole Installation

In order to install Direct Burial Light Poles the correct backfill material for differing soil conditions should be used. The following guidelines are suggested:

Solid Rock Conditions: Crushed rock of 3/4 inch or less or cemented sand should be utilized for backfill.

Poor Soil Conditions: Consisting of loose rock, gravel, highly organic solids, or any other type of soil or conditions that inhibits the creation of a stable structural base. Local experts knowledgeable in existing soil conditions in the local area should be consulted to determine proper soil compaction.

Average Soil Conditions: Consisting of clay, silt, moderately organic soil, or areas with standing water during rainy season. Additional crushed rock to 3/4 inch or less should be added to the excavated material for backfill.

Make The Hole: Generally holes should be round with smooth vertical sides consisting of undisturbed soil for best compaction and stability of poles. Diameter of holes should be about twice the diameter of the pole at its base. Holes should be hand dug or augured. For general burial depth consult the chart below:

Overall Shaft Length Burial Depth
8-10 FT 2 FT
11-17 FT 3 FT
18-29 FT 4 FT
30-40 FT 5 FT
30-40 FT 5 FT
41-45 FT 6 FT

Wire the Pole: Complete wiring utilizing approved methods.

Install the Pole: In many cases composite poles can be manually lifted into place and inserted into the hole.

Plumb the Pole: Use a plumb bob to level and align the pole.

Backfill the Hole: Fill and tamp every 6 to 8 inches of backfill. Frequent tamping is important for installation.
