Cost-effective non-metallic PVC sheet pile is under development using thermoplastic
fiber-reinforced composites that may meet the strength, stiffness, lightness, creep,
fatigue, impact, and durability requirements and provide another alternative to steel sheet
piling. This sheet piling in the future should satisfy both deflection and strength criteria
for failure.
Both PVC and polymer composite sheet piles may suffer abrasion and thickness
reduction by coarse sand or other debris rubbing against the sheet pile over time. Special
protective coatings or design may be required where such problems are present.
