Notes:

Footnote 1

The allowable loads are only valid when the product is installed in granular soil or silt. Special attention is required when the auger-installed steel piles are installed in a recently backfilled site or where the granular material exceeds 200 mm in diameter or in cohesive soils. In these cases, Table 4.1.1 does not apply and the allowable loads need to be determined by on-site confirmatory testing.

Footnote 2

Granular soils (coarse grained soil) are non-cohesive soils; for example, sand, gravel or silt with little or no clay content and little to no cohesive strength.

Footnote 3

Silt is that portion of soil material passing through a 200 (75-µm) U.S. standard sieve that is non-plastic or very slightly plastic and exhibits little or no strength when air-dried.
