SPiRe®+ Seawall Repair System
The Next Generation Solution for Seawall and Bulkhead Rehabilitation
A New Approach to Seawall Repair in the Age of Rising Coastal Demands
Seawalls and bulkheads around the world are under increasing stress due to aging infrastructure, corrosion, and rising sea levels driven by climate change.
Traditional repair methods—such as patching, coating, or full replacement—are often costly, disruptive, and short-lived.
SPiRe®+, developed by QuakeWrap, Inc., is a next-generation seawall repair system that creates a new, durable structural face in front of deteriorated walls—restoring strength, stopping corrosion, and extending service life for decades.
What is SPiRe®+?
SPiRe®+ is an advanced composite panel system that builds upon the proven success of the original SPiRe® (Sheet Pile Repair) technology .
While SPiRe® focused primarily on sheet pile repair, those panels were primarily designed as stay-in-place formwork. In contrast, SPiRe®+ expands the concept into a complete seawall repair and strengthening solution suitable for a wide range of structures and conditions.
The system uses pultruded FRP panels with integral structural features that:
- Provide high strength and stiffness
- Act as stay-in-place formwork
- Replace traditional reinforcing steel
- Create a long-lasting, corrosion-resistant barrier
The SPiRe®+ Solution: A Composite Structural Barrier
Most seawall failures are caused by:
- Corrosion of steel sheet piles or reinforcing steel
- Loss of soil behind the wall due to leakage
- Increased loads from higher water levels and storm surges
- Long-term exposure to harsh marine environments
Conventional repair methods:
- Do not stop corrosion at its source
- Require extensive surface preparation
- Often involve cofferdams and heavy construction
- Result in high costs and long project durations
The SPiRe®+ Solution: A Composite Structural Barrier
SPiRe®+ transforms a deteriorated seawall into a composite structural system by installing engineered panels in front of the existing wall.
Installation Concept
- Panels are positioned in front of the seawall
- Panels are anchored mechanically to the existing structure
- Panel joints are sealed to create an impervious barrier
- The space between panel and wall is filled with grout
The Result
- A new structural face independent of the deteriorated wall
- A watertight system that prevents further soil loss
- A corrosion-resistant barrier that blocks oxygen and moisture
- A load-sharing composite system that enhances performance
Key Advantages Of SPiRe®+ Seawall Repair
Designed for Seawall Rehabilitation
Unlike systems limited to sheet piles, SPiRe®+ is engineered for full seawall repair, including complex geometries and varying site conditions.
No Need for Full Replacement
- Eliminates demolition of existing seawall
- Avoids costly reconstruction
- Extends service life by decades
Rapid Installation
- Lightweight panels
- Minimal heavy equipment
- Can often be installed without cofferdams
Superior Durability
- Vinyl ester resin for harsh marine environments
- Impervious outer surface prevents corrosion
- Long-term resistance to chemicals and saltwater
Integrated Structural System
- Acts as formwork, reinforcement, and barrier
- Eliminates need for conventional rebar in many applications
- High strength-to-weight ratio
Applications of SPiRe®+
SPiRe®+ is ideal for a wide range of seawall and waterfront repair projects, including:
- Steel sheet pile seawalls
- Concrete seawalls and retaining walls
- Timber bulkheads
- Concrete Decks and Girders in Ports and harbors
- Industrial waterfront facilities
- Pump stations and marine structures
It is especially effective in environments exposed to:
- Saltwater and brackish water
- Tidal fluctuations
- Storm surge and wave action
- Industrial and chemical exposure
In addition to marine infrastructure, SPiRe®+ is ideal for repair of corroded slabs in industrial buildings, mines, chemical plants, etc. Access to these slabs is often limited in such facilities. The rapid installation of these panels that require virtually no surface preparation offers a significant advantage in such projects.
Similarly, many older slabs in buildings are thin and have low flexural capacity. When these floors are being retrofitted for increased live load capacity, the use of SPiRe+ panels can make such retrofit projects more efficient and with minimal impact on ductwork and other elements that may be supported below the slab.
From SPiRe® to SPiRe®+: Evolution of a Proven Technology
The original SPiRe® system introduced the concept of using composite sandwich panels for sheet pile repair .
SPiRe®+ builds on that foundation with:
- Higher structural capacity by including reinforcing elements as T profiles
- Improved panel connections
- Greater versatility for seawall applications
- Faster and more efficient installation

Proven Performance in Demanding Environments
SPiRe® and SPiRe®+ technologies have been successfully used in:
- Coastal seawalls
- Industrial facilities
- Ports and marine terminals
- Large-scale international projects
These systems have demonstrated:
- Excellent long-term durability
- Resistance to corrosion and environmental damage
- Significant reduction in construction time and cost
The ability to perform the repairs with these products under water without the need for any costly cofferdams significantly reduces the construction time and cost on most marine repair projects.

Sample field Installations
Grotton, Connecticut
In one of the first and largest applications, an 1800 ft x 18 ft (550 m x 5.5m) section of a steel seawall is being repaired for this submarine repair facility.
City of Weston, Florida
The corroded steel seawalls in two pump stations were repaired; some of these panels had significant section loss and holes due to corrosion.
Queens, New York
A deteriorated timber bulkhead with settlement due to loss of soil was repaired in Anable Basin.
Bridge Pier Wall, North Dakota
Two partially-submerged concrete pier walls were repaired by attaching 9-ft (2.7m) tall panels to the faces of the walls.
Port Canaveral, Florida
The concrete bulkhead at Grill was strengthened by positioning the SPiRe+ panels horizontally, spanning between the piles.
Additional Applications
- Strengthening of corroded slabs in coastal communities
- Repair of slabs in industrial plants
