PFI has experience with working DOT projects across many states. Our primary specialty is Drilled Shafts which is a common foundation type for signage structures, traffic control structures as well as occasional highway lighting structures. We utilize the wet slurry in challenging soil conditions, can perform drilling in rock, dry holes and can install foundation casings or bases with the vibratory hammer.
Our primary areas of work:
- Drilled Shafts
- Direct Embed Pole Bases (Rock Backfill or Concrete Backfill)
- Vibratory Caisson Installations (Temporary or Permanent)
