Vinyl sheet piling offers an alternative to underwater concrete forming. Its high density plastic composition allows for a long lasting, protective barrier between the water and the structure. The sheeting can be driven similarly to traditional steel sheet piling using a vibratory hammer, or it can toed in using grout bags placed in strategic locations.
Once in place the sheeting is reinforce with a steel waler system and anchored to the existing structure. Preplaced aggregate concrete is then injected or self-consolidating concrete is then tremmied behind the sheeting as it serves as a permanent form. Once completed the vinyl sheeting and newly placed concrete creates a tough and aesthetically pleasing barrier to the structure. Several different sheeting types and shapes are available for any application.
