Abstract: General: Timber piling can suffer severely from ice damage. As ice forms on the water's surface, it adheres to the rough surface of the timber piling and forms an ice collar. As more Ice forms and thickens and the water level changes due to tides, the ice tries to float up and down, exerting an uplift force on the piling. When the action is repeated, the piling is lifted higher (or "jacked") and may be completely loosened from the bottom. If the piling is not lifted the first season, the chafing more susceptible to uplift in successive seasons. Several cycles of freezing and jacking have lifted the mooring pile pictured here 5 ft (see Figure 1).
