ABOUT XPile™

Advanced Fiber Reinforced Polymer (FRP) Marine Piling for Long-Term Performance

Name: XPile Marine Piling
Brand: XPile

XPile™ Composite Fiber Technologies (CFT) marine pilings are engineered from strength, durability, and reliability in the harshest marine environments.

WHAT IS XPile™

Engineered for Strength in Marine Environments

XPile™ is a fiber reinforced polymer (FRP) marine piling developed to support long-term performance in demanding marine environments. Manufactured using pultruded fiberglass and vinyl ester resin, XPile™ combines structural strength with durability suited for coastal and marine applications.

Designed for reliability in harsh conditions, XPile™ maintains its integrity over decades of exposure to saltwater, moisture, and heavy loading. Its lightweight composition supports efficient handling and installation, while its engineered structure ensures consistent performance across a wide range of projects.

XPile™ represents a modern approach to marine piling—focused on long service life, dependable performance, and practical jobsite efficiency.

INSTALLATION

Designed for Efficient Marine Installation

DRIVING METHODS

Vibratory hammer (preferred- works in all soil types)
Impact hammer (precision driving)
Drop hammer (final set confirmation)
Machines from 5.5 ton to 25-ton

SPLICING

Bolted internal connection. Maintains full structural strength. Multiple splices possible.

CUTTING

Standard grinder with diamond-tip blade. Can be handled by a single operator.

SOIL CONDITIONS

Sandy loam, clay, silty soils, acid sulfate soils.

PERFORMANCE ADVANTAGES

Engineered Advantages for Marine Performance

50-year design life with minimal maintenance

No corrosion- chemically inert, will not rust or rot

Immune to marine borers- no organic material to consume

No electrolysis- safe for boat hardware and marina fittings

Acid sulfate soil resistant- performs where wood and steel degrade

Yield technology – flexes on impact, returns to position, protects vessels

Non-leaching and non-toxic – safe for marine ecosystems

Reduced embodied carbon compared to traditional materials
