A brief listing of some of the more important developments which Gerwick has pioneered:

• Prestressed concrete piling
• Offshore concrete platforms in North Sea, North Atlantic, Australia, and the Arctic, including iceberg-resistant structures
• Foundations for bridges using precast segments and underwater concrete
• Large diameter tubular piles and micropiles for overwater bridges in seismic zones and to resist ice loads
• In-the-wet construction of river navigation projects using precast concrete shells in-filled with tremie concrete
• High-performance structural underwater concrete
• Slurry diaphragm underground walls with continued improvements (SPTC Walls)
• Double-headed reinforcement (T-hood bars)
