Product Description

                                           Pullout Resistance Chart

Notes:

1. In determining vertical depth to the Ground Anchor, the thickness of topsoil, peat, soft clay and similar soft soils should not be included.
2. The applicable class of soil that is present within a zone from the Ground Anchor to a point from one to three feet above the anchor, depending upon anchor size.
3. For Ground Anchors at a minimum depth in Soil Classes 1-4, reduce ultimate pullout resistance by percentage given for each foot ground water table is above the anchor. No reduction is required for hardpan.
4. For Ground Anchors driven to depths greater than the minimum Soul Classes 1-4, the ultimate pullout resistance may be increased by the percentage given for each additional foot below the specified minimum. The ultimate pullout resistance

Soil Classification

Hardpan: A very compact heterogeneous mixture of soil particles ranging from those of silt and clay size to sand, gravel and perhaps boulders and generally exhibiting very high dry strength.

Soil Classes 1-4: Cohesion-less sands and gravels which are non-plastic in the wet state and which possess no strength or cohesion between individual mineral particles or rock fragments in the dry state.

Class 1: Dense Gravel: Dense well-graded sand and gravel with angular particles.

Class 2: Medium-dense sandy gravel and gravelly sand; Medium-dense to dense well graded sand.

Class 3: Loose to medium dense well-graded sand; Medium \dense to dense medium to find sand.

Class 4: Loose fine sand and loose medium sand with well-rounded particles: Uncompact sand fill.
