There are considerable problems associated with the use of traditional piling and sheet piling materials in corrosive soils and marine environments. The durability of concrete, corrosion of steel, and vulnerability of timber piles to marine borers are serious hindrance to construction in these environments. Composite materials such as fiber-reinforced polymers can offer performance advantages when compared to steel, concrete or timber. The objective of this research is to develop, test, and demonstrate the viability of polymer composite piling in corrosive soils. The research seeks to evaluate engineering performance and chemical integrity of different types of plastic piles under corrosive environments and develop engineering guidelines for product design and material performance.
