PREFACE:

there is an increasing demand for piling made of materials that exhibit more beneficial characteristics than are available in traditional piling.

 Over the past decade Lancaster Composite Inc. has focused its resources on the successful design, development and commercial implementation of a marine piling that is economical, corrosion resistant, environmentally safe and readily available. Our Precast FRP Composite Pile is commercially available as Composite Pile 40 (CP40). 

Thousands of CP40 piling have been installed nationally as the BEST VALUE design solution for a variety of public and private projects. The CP40 pile is resistant to decay, marine borer attack and consistently demonstrates reliable strength, while providing marine structures with longer service lives, and lower life cycle costs.

 1.1 PILING AND MATERIAL DESIGN Lancaster CP40 marine piles are a composite of a fiber reinforced polymer (FRP) tube and a high strength concrete core.

 The core, a Portlandbased expanding concrete, prevents crush/buckle of the FRP tube under bending, providing bending strengths equal to steel for the same diameter. The FRP tube, possessing substantial longitudinal.

The FRP tube, possessing substantial longitudinal and circumferential reinforcement, provides high tensile strength. The core expands and sets with permanent positive stress against the inside wall of the FRP tube. The FRP fully protects the entire column from corrosive agents in the environment. The FRP tube and the concrete core work in a synergistic fashion, providing superior benefits of the two materials. The FRP tube, with its unique fiber architecture, provides unprecedented containment of the concrete core, enabling compressive strength up to three times the tested PSI of the concrete core.
