For decades saltwater seawalls have been constructed using precast concrete panels with king piles and batter piles driven into the ground to secure it in place. The final step consists of a concrete cap that is poured in place to connect all of the components together. These “traditional style” seawalls are installed with a barge and crane. Early walls only had the vertical king piles, and later on batter piles were incorporated as additional reinforcement. All precast walls and pilings are designed with a minimum of 5000 psi concrete and contain reinforcing steel inside.
Traditional style seawalls are still installed new today, although we expect to see their popularity decline as hybrid pour in place concrete seawalls gain in popularity.
