SPiRe® Sheet Pile Repair System

Advanced Composite Solution for Steel Sheet Pile Walls


Restore and Protect Corroded Sheet Pile Walls Without Replacement

SPiRe® is a proven sheet pile repair system developed by QuakeWrap, Inc. to restore and protect deteriorated steel sheet pile walls, bulkheads, and waterfront retaining structures.

This innovative composite panel system eliminates the need for costly demolition and replacement while providing long-term corrosion protection and structural enhancement.

Originally inspired by sandwich construction used in aerospace and marine industries, SPiRe® brings advanced composite technology to civil infrastructure—offering a smarter, faster, and more durable approach to steel sheet pile repair.

The Challenge: Deterioration of Steel Sheet Pile Walls

Steel sheet pile walls are widely used in marine and waterfront construction, but they are highly vulnerable to long-term deterioration—especially in the splash and tidal zones.

Common problems include:

  • Severe corrosion and section loss
  • Perforations and leakage through the wall
  • Soil loss behind the wall leading to voids and settlement
  • Reduced structural capacity and stability

Traditional repair methods often involve:

  • Welding steel patches (temporary and labor-intensive)
  • Coatings that eventually fail
  • Full wall replacement (expensive and disruptive)

These approaches do not eliminate the root cause of deterioration: continuous exposure to water and oxygen.

Sheet Pile Repair: A Better Alternative to Replacement

SPiRe® was specifically developed as a steel sheet pile repair system that addresses both structural deterioration and corrosion at the source.

Instead of attempting to patch the damaged wall, SPiRe® creates a new structural face in front of the existing sheet pile wall.

This approach:

  • Restores lost section without welding or pile replacement
  • Seals the wall and prevents further leakage
  • Blocks oxygen and moisture to stop corrosion
  • Extends the service life of the structure by decades

For owners and engineers, SPiRe® provides a cost-effective alternative to full sheet pile wall replacement.

The SPiRe® Technology: Sandwich Construction for Infrastructure

SPiRe® panels are manufactured using sandwich construction technology, consisting of:

  • Outer skins made of glass or carbon fiber reinforced polymer (FRP)
  • A lightweight foam core that provides stiffness and stability
  • Resin infusion processes that create high-strength, void-free laminates

This configuration results in panels that are:

  • Lightweight yet structurally efficient
  • Easy to transport and install
  • Highly resistant to corrosion and harsh environments

When combined with grout in the field, SPiRe® panels form a composite structural system that works together with the existing wall.

SPiRe® panels can be made in custom-shapes as were the requirements for this project in San Francisco, CA

Installation Concept

The SPiRe® system is designed for rapid and efficient installation in marine environments:

  1. Panels are placed in front of the existing sheet pile wall
  2. Panels are anchored mechanically to the structure
  3. Joints are sealed to create an impervious barrier
  4. The annular space between panel and wall is filled with grout

The result is:

  • A new protective and structural face
  • A watertight barrier that prevents further deterioration
  • A load-sharing composite system that enhances performance

Proven Performance in the Field

SPiRe® introduced a new approach to marine sheet pile rehabilitation, using composite sandwich panels as stay-in-place structural forms.

The system has been successfully used to repair corroded sheet pile walls in:

  • Coastal seawalls
  • Industrial facilities
  • Pump stations and waterfront infrastructure

These projects demonstrate how SPiRe® can restore performance while significantly reducing construction complexity and cost.

Sample field Installations

Chesapeake, Virginia
A 900+ ft long seawall was successfully rehabilitated using FRP panels, eliminating leakage and restoring structural capacity.

Port of West Saint Mary, Louisiana
Seawall repairs were completed underwater without cofferdams, minimizing downtime and cost.

Port of Melbourne, Australia
In one of the largest applications of this technology, 1.25 km (0.75 miles) of a corroded steel sheet pile is being repaired at this major port in Australia.

Additional Applications:

  • Ports and harbors
  • Industrial waterfront facilities
  • Coastal protection systems

While SPiRe® is optimized for sheet pile repair, many projects require a broader solution for full seawall rehabilitation.
