Advantages over Geopiers
Helical Piles offer advantages over geopiers:
- Geopiers are limited in the depth they can be used.
- Geopiers do not handle lateral loads well. Helical piers can be battered to handle high lateral loads .
- Geopiers do not work well sands with high groundwater. For Geopier water table needs to be below the bottom of the pier. Helical piles can be installed and function perfectly in any groundwater level or in standing water.
- Expansion soils are very problematic for geopiers. Helical piles are unaffected by expansive soils.
- Wide heavy load applications are an issue for geopiers.
- Helical piles handle tension loads just as easily as compression loads. Geopiers require special uplift hardware for tension loads.
- Helical piles produce no vibration.
- Helical piles have no spoils to be disposed.
