New Seawall Erosion Control Series – 4. A Holistic Solution

In constructing new seawalls, it’s essential to employ a holistic approach that combines advanced techniques for enhanced longevity and stability. This approach includes the use of polymer grout injection, hydrostatic pressure control, and ensuring compliance with NSF/ANSI/CAN 61 standards for repair materials.

Polymer Grout Injection and Hydrostatic Pressure Control

As previously discussed, injecting SW-RP1 structural polymers into the soil behind seawall joints strengthens the seawall, preventing soil migration and water infiltration issues. Installing a hydrostatic pressure control system, consisting of dewatering channels and soil filters, relieves hydrostatic pressure and prevents erosion.

NSF/ANSI/CAN 61 Standards: Ensuring Safety and Quality

An essential aspect of seawall construction is the use of materials that meet NSF/ANSI/CAN 61 standards. These standards, set by the National Sanitation Foundation (NSF), involve rigorous testing to ensure that materials used in or around water are safe and do not adversely affect water quality. Compliance with these standards is crucial for any materials used in seawall repair or construction, as they ensure the safety of the aquatic environment. SW-RP1 polymer repair material meets these standards.

The Combined Benefits of a Holistic Approach

Combining polymer grout injection, hydrostatic pressure control, and adherence to NSF/ANSI/CAN 61 standards significantly enhances the overall effectiveness and durability of new seawalls. This holistic approach not only addresses the immediate structural needs but also ensures long-term environmental safety and compliance with public health standards.

Longer Warranties and Reduced Maintenance Costs

Employing these methods collectively can lead to longer warranties for new seawall constructions, as the enhanced durability reduces the risk of early failure. Additionally, the long-term stability offered by these combined methods translates into reduced maintenance costs, offering significant financial benefits over the seawall’s lifespan.

Holistic Seawall Erosion Control

The integration of advanced construction techniques and materials that meet stringent safety standards represents a sustainable and responsible investment in coastal protection. This holistic approach in new seawall construction not only ensures the structural integrity and longevity of the structure but also aligns with environmental safety and public health concerns, making it a prudent choice for effective coastal management.

New Seawall Erosion Control Series – 3. Addressing Hydrostatic Pressure

In new seawall construction, a key challenge is managing hydrostatic pressure—the force exerted by water on the seawall. This pressure can be detrimental to the integrity of the structure, especially if not properly addressed. Excessive hydrostatic pressure can lead to structural damage, such as cracking, bulging, or even collapse, particularly in areas with high water tables or frequent storm surges. Seawall Repair Network® has developed a comprehensive approach to control hydrostatic pressure in new seawalls. This system is designed to regulate the pressure and prevent the common issues associated with unmanaged hydrostatic forces.

The Hydrostatic Pressure Control System Installation Process

The installation of the Hydrostatic Pressure Control System involves several key steps:

1. Stabilizing Soil and Sealing Leaks with SW-RP1: Initially, the contractor injects SW-RP1, a specialized polymer repair material, behind the seawall on the landward side. This material transforms unstable soil into a solid, lightweight mass, providing a supportive medium for the creation of dewatering channels. Additionally, SW-RP1 seals the joints between the concrete seawall panels, preventing further water intrusion and soil erosion.
2. Creating Dewatering Channels: These channels are essential for relieving hydrostatic pressure. As specified by the US Army Corps of Engineers, the channels are placed at the same height as the main waterline mark.
3. Installing Hydrostatic Pressure Release Filters: These filters are installed in the dewatering channels. They are crucial in allowing water to pass back and forth, maintaining an equilibrium of hydrostatic pressure. They also stop soil migration from the landward side of the seawall, thus preventing erosion and void formation.

Benefits of the Hydrostatic Pressure Control System

The Hydrostatic Pressure Control System offers several benefits in new seawall construction:

• Prevention of Structural Damage: By regulating hydrostatic pressure, the system minimizes the risk of cracks and shifting panels.
• Long-Term Stability: The combined system of soil solidification, dewatering channels, and pressure release filters ensures a more stable and durable seawall structure.
• Cost Efficiency: Incorporating this system during construction can reduce long-term maintenance needs and extend the seawall’s lifespan, resulting in overall cost savings.

A Comprehensive Solution for New Seawalls

The hydrostatic pressure control system from Seawall Repair Network® provides a well-rounded solution to the challenge of water pressure in new seawall construction. By integrating this system, stakeholders can significantly enhance the resilience and longevity of seawalls, ensuring effective coastal protection for years to come.

New Seawall Erosion Control Series – 2. Reinforcing the Panel Joints

A concerning trend has emerged recently in which new seawalls, meant to withstand decades of coastal forces, are failing within just a few years due to cost-cutting construction methods that deviate from proven standards. Specifically, instead of using a continuous layer of high-quality filter fabric behind the wall to prevent erosion, many modern seawall projects utilize just small strips of inexpensive landscape fabric secured inadequately. This leads to detachment of the fabric and subsequent soil erosion, destabilizing the seawall’s foundation. The lack of supporting soil causes cracking and shifting, exposing rebar to rust, necessitating repairs, and risking safety. In addressing these challenges, Seawall Repair Network® has developed a focused approach: injecting polymer grout into the soil behind seawall joints.

Polymer Grout Injection: A Focused Solution

The process of injecting SW-RP1 polymer grout into the soil behind seawall joints is a precise response to concerns about modern seawall construction. This repair material acts to seal the joints and permeate the surrounding soil, creating stable support for the seawall. This approach directly reinforces the seawall at its weakest structural points, countering the soil erosion and instability that can occur with less robust construction methods.

Long-Term Impact on Seawall Stability

By enhancing the soil stability behind the seawall, the polymer grout injection offers a more reliable long-term solution for new seawall construction. This method helps in extending the seawall’s lifespan, potentially offering decades of stability. The polymer material’s resilience also means it can withstand environmental stresses better than some traditional materials.

Reinforcing the Panel Joints for Stronger Seawalls

Incorporating polymer grout injection into new seawall construction represents a practical step towards more effective and durable seawalls. This method offers a way to address some of the shortcomings of modern construction techniques, ensuring that new seawalls continue to provide reliable coastal protection for decades to come.

New Seawall Erosion Control Series – 1. Understanding the Challenge

Seawalls serve as guardians against the relentless forces of nature, protecting coastal properties and landscapes. However, the construction of these vital structures is often fraught with challenges. A concerning trend has emerged in the world of seawall construction: some new seawalls, which should stand strong for decades, are showing signs of failure within the first few years of construction. This alarming issue not only poses a risk to property but also calls into question the methods and materials that some are using in modern seawall construction.

A Common Cause of Early Seawall Failure

The primary cause for early failures in many new seawalls is a shift away from traditional, more reliable construction methods. Historically, seawall construction adhered to standards set by the Army Corps of Engineers, which included the use of high-quality filter fabric on the back side of the seawalls. This fabric played a crucial role in stabilizing the structure by preventing soil erosion from behind the wall, thereby maintaining its integrity. In contrast, many modern construction practices, driven by cost-cutting measures, have deviated from this proven method. Instead of using a continuous layer of high-quality filter fabric, they often resort to using only small strips of inexpensive landscape fabric, covering just the joints. This approach, which involves securing the fabric strips with furring strips similar to those used in carpet installation, is significantly less effective. The fabric, not designed to withstand the demands of seawall construction, can easily detach even during the soil backfill process. This inadequate method leads to the quick deterioration of the seawall, as the soil erosion from the landward side compromises the seawall’s stability, triggering a cascade of structural failures.

Consequences of Cutting Corners

One of the most immediate issues is the loss of soil from the landward side into the waterward side of the seawall. This soil erosion, triggered by the detachment of cheap landscape fabric strips used in place of the traditional high-quality filter fabric, leads to an unstable foundation behind the seawall. As the soil stability behind the seawall deteriorates, a domino effect of structural failures begins. The lack of supporting soil results in the seawall becoming weak against the pressure from the water. This instability can cause the panels to shift, seawall caps to crack, and, in cases where the seawall is constructed of concrete, the rebar within it to be exposed to water and start to rust due to cracking. These structural failures not only lead to significant repair costs but also pose a potential risk to public safety, especially in areas where seawalls play a crucial role in protecting properties and infrastructure from water damage.

A Holistic Solution

Upcoming posts in this series will explain two pivotal solutions that address these challenges in new seawall construction: the injection of polymer materials into the soil behind seawall panel joints and the installation of hydrostatic pressure control systems. The polymer injections serve to solidify the soil, creating a robust, bedrock-like foundation that significantly enhances the stability of the seawall. This method directly combats soil erosion and ensures the longevity of the structure. Concurrently, the hydrostatic pressure control systems are designed to manage the immense water pressure that seawalls face. First, the proprietary polymer repair material SW-RP1 is injected behind the seawall panel joints to solidify and stabilize the soil. Next, drainage channels are cored through the seawall and polymer-solidified soil at strategic weep hole locations. Finally, specialized pressure release filters are installed within these drainage channels. These filters allow water to pass while blocking soil migration, thus equalizing hydrostatic pressure and preventing erosion. Together, the soil stabilization, drainage channels, and pressure filters provide integrated management of hydrostatic forces, preventing structural degradation over time. By transforming the soil into a supportive medium and regulating water pressure, these systems ensure the ongoing structural integrity and functionality of the seawall.
