Pier Drilling in Contra Costa & Alameda County

Piers are being drilled to form a stabilizing structure beneath a future swimming pool

Dunn Company provides reliable pier and foundation drilling services. We perform drilling for pier and grade beam foundations, retaining walls, and fence posts. We also drill for haunch piers for underpinning.

Our pier drilling in Alameda bits range in size from 12 inch to 36 inch. The drill setup is mini excavator-mounted, has two speeds for varying soil conditions, and is capable of depths to 14 feet without stemming. This equipment is ideal for a wide variety of pier drilling operations.

Some circumstances may call for a larger bore or more depth. We have access to larger rigs when needed.

Pier drilling services generally include safety plating of holes, steel rebar placement, concrete pouring and the removal of all spoils from the operation. Besides Alameda, we also have pier drilling services in Contra Costa for your projects.
