Concept

Soil slip lines (soil failure) form along a Fibonacci spiral shape.

The angled wall of the Earth Grip take advantage of this fact.

The angled sides dramatically increase the volume of soil to resist against.

Angled sides is what makes Earth Grip unique in the world of pile stability.

Basically, angled sides are the “secrete sauce” of Earth Grip and is one of the features of the product that is patent pending.

 

In the soil failure model below you’ll see how the vertical side of the concrete footing pushes horizontally.
Only a small amount of soil need to ‘give way’ and the concrete pier fails.

Comparison

Because all foundations push against soil for support, the amount of soil they push against is an important factor in their stability.
