Horizontal cracks (transverse to longitudinal reinforcement or strand) greater than 1/16 inches wide.

Piling will be rejected if crack occurs in a portion that will be below ground or water level after driving.
If crack occurs in a portion that will be above grade or water level, the Contractor may opt to cut back beyond the crack and rebuild to required elevation.

Horizontal cracks less than 1/16 inches wide.

Inject the cracks with epoxy in accordance with Section 3.7 of this manual.
If cracks develop that will be inaccessible in final configuration, cease driving operations and repair cracks before continuing.

Vertical or diagonal cracks.

In most cases a piling member will be rejected if vertical or diagonal cracks form during driving operations.
If the Engineer approves repair of vertical or horizontal cracks, inject with epoxy in accordance with Section 3.7 of this manual.

Fine hairline cracks (less than 0.006 inches) or surface checks that do not extend to the plane of the nearest reinforcing steel will not require repair and will not be cause for rejection.
