Seawall Sinkholes – Soil Depressions and Structural Integrity

 

Body - Seawall SinkholesSeawalls play a crucial role in protecting waterfront properties from erosion and flooding. However, these protective structures face their own threats. One of the most insidious dangers is seawall sinkholes. These soil depressions can severely compromise the structural integrity of seawalls, leading to potential failure if not addressed promptly.

The Hidden Danger of Soil Erosion

Behind every seawall lies a complex interplay of forces. Over time, various factors can cause the soil to erode. As a result, loose soil and dangerous voids form. These, in turn, can cause soil depression around the wall. The process often begins with something as seemingly innocuous as rainwater accumulation. Subsequently, this buildup creates hydrostatic pressure. Consequently, cracks form in the seawall structure. Water then seeps through these cracks, carrying away vital supporting soil.

Recognizing the Signs of Seawall Sinkholes

Early detection is key to preventing catastrophic failure. Property owners should be on the lookout for several telltale warning signs. Cracks in the seawall cap or rust stains on the concrete often indicate underlying issues. Additionally, visible soil depressions near the seawall are a clear red flag. Furthermore, any noticeable tilting or movement of the seawall structure warrants immediate attention.

Lasting Solutions for Sinkhole Repair

Fortunately, Seawall Repair Network® offers effective solutions for combating seawall sinkholes. SRN contractors use SW-RP1, an environmentally friendly repair polymer, to stabilize the eroded soil. This approach not only fills existing voids but also strengthens the surrounding soil.

Beyond Sinkholes: Comprehensive Seawall Protection

Addressing seawall sinkholes is just one part of a holistic protection strategy. Contractors may recommend additional measures to ensure long-term stability. For instance, installing a hydrostatic pressure control system can prevent water buildup behind the seawall. This system features pressure-release filters that allow water to flow from the landward side into the waterward side while preventing soil from leaking through the structure. Moreover, seawall cap repairs can restore surface integrity. In high-risk areas, contractors might suggest installing an anchoring system for added support.

The Importance of Professional Expertise

Dealing with seawall sinkholes requires specialized knowledge and experience. Attempting DIY repairs can lead to further damage or ineffective solutions. Professional contractors possess the necessary skills to assess the situation accurately. They can then implement the most appropriate and long-lasting repairs.

How to Repair a Seawall

Body - How to Repair a SeawallThe powerful forces of water can eventually damage any seawall. A seawall has many components that all need to work together. When one part fails, the entire structure is at risk. A couple of common causes typically make seawalls fail prematurely. Understanding seawall failure is an essential prerequisite to learning how to repair a seawall.

Hydrostatic Pressure and Seawall Failure

Hydrostatic pressure buildup on the landward side is one of the main causes of seawall failure. Water accumulation on the landward side of the seawall causes this pressure to build up. This buildup often causes cracks to form in the seawall, allowing water to leak through from the landward side to the waterward side. As the water leaks through, it carries supporting soil with it. We call this process soil migration.

Soil Migration and Seawall Failure

Soil migration can also cause voids to form behind the seawall when the water washes soil away from behind the structure, leaving a gap between the seawall and the ground. These void formations further destabilize the seawall, increasing the risk of failure. If no one addresses the combination of hydrostatic pressure buildup and the resulting soil migration, it can quickly lead to seawall failure.

How to Repair a Seawall with Structural Polymers

Fortunately, a solution exists that doesn’t require completely replacing the seawall. Professionally trained contractors use a proprietary repair process to fix damaged seawalls. Here’s how it works:

Step 1: Stabilize Soil, Seal Leaks, and Fill Voids with Structural Polymers

First, repair crews perform deep injections of SW-RP1 polymer repair material directly behind each seawall panel joint. This material fills any voids while also penetrating and hardening the surrounding soil to the strength of crystalline bedrock. Additionally, it fills cracks and old weep holes to seal any leaks. SW-RP1 is NSF-certified to meet strict environmental standards.

Step 2: Install New Pressure Relief System

Next, the crew cores new channels through the polymer-filled weep holes, extending into the soil behind the wall. They then install proprietary pressure release technology in these channels.

This technology regulates hydrostatic pressure by allowing water to flow through from the landward side to the waterward side. Moreover, it stops soil migration by preventing soil from passing through the channels.

The Result: A Permanent Fix

The high-strength SW-RP1 material provides critical structural support. Combined with the pressure regulation, this protects the seawall from any subsequent shifting, damage, or collapse. It’s a permanent, eco-friendly solution that costs up to 80% less than total seawall replacement. Moreover, this process is much faster and less invasive than replacement.

Seawall Washout Repair – An Environmentally Friendly Solution

Body - Seawall Washout Repair - An Environmentally Friendly SolutionSeawalls protect coastal properties from erosion and water damage. However, as they age, they can suffer from various issues, including soil erosion and void formation on the landward side. This article explores the causes of seawall soil erosion, the domino effect it creates, and innovative seawall washout repair solutions.

The Causes and Effects of Soil Washout

The deterioration of geotextile filter fabric is one of the primary causes of soil erosion. As this fabric deteriorates, soil migrates through the panel’s vertical joints and weep holes during water events. Consequently, this migration leads to void formations behind the seawall, compromising its structural stability. Supporting soil washout can create a domino effect that ultimately leads to complete structural failure if not addressed promptly. Soil erosion and void formations cause deterioration of the supporting soil, leading to increased hydrostatic pressure. As a result, this pressure can damage the seawall panels and cap, destabilizing the entire structure.

Innovative Solutions for Seawall Repair

To combat seawall damage and restore stability, contractors can inject specialized polymers into the soil adjacent to the structure. These polymers saturate the soil, fill voids, and create a matrix that binds soil particles together. Consequently, the seawall gains increased foundational support and better withstands the forces of waves and tides. Additionally, these polymers naturally seal any leaks in the seawall structure as they spread, providing a comprehensive repair solution. Seawall Repair Network® polymers are NSF-certified to comply with strict environmental standards.

The Environmental Impact of Seawall Washout Repair

Seawall washout repair also has a significant impact on the surrounding environment. Silt and soil containment is crucial for maintaining the aesthetic beauty of water bodies and preserving marine habitats. By implementing eco-friendly containment strategies, contractors minimize the disturbance to aquatic ecosystems and reduce the need for disruptive and costly dredging. Furthermore, effective containment methods trap potentially contaminated soil, safeguarding the health of the aquatic ecosystem and protecting water quality.

Case Study – Seawall Soil Reinforcement

Body - Seawall Soil ReinforcementA resident of Punta Gorda, Florida noticed that the soil behind her seawall was eroding. She attempted various fixes such as dumping bags of concrete, backfill, and gravel, but the soil continued to wash out from below the seawall. It was determined that gaps and cracks in the seawall were allowing soil to be lost.

Repair Materials

Seawall Repair Network® contractor Anderson Dock and Lift used SW-RP1 polymer resin to fill the gaps, encapsulate the soil, and reinforce the integrity of the existing seawall structure. This material can expand 50 times its liquid volume and has an ultra-low viscosity allowing it to thoroughly permeate cracks and voids.

Procedures

A Polyshark pump was used to push SW-RP1 through two 400-foot lines to the seawall, where small 1/2” galvanized rods were inserted below the waterline. Upward staging was used to inject the material into the soil at every foot of elevation until the product could be seen as it reached small cracks in the wall and under the seawall. As the resin filled cracks and spaces behind the wall, bubbles could be seen releasing from known and previously undetected gaps as trapped air was pushed out.

Results

The expanding resin successfully filled leaks at the seawall base and permeated soil voids behind the entire wall face. The previously undetected leaks were also sealed, waterproofing the structure and stabilizing the soil behind it. This solution repaired the failing seawall and prevented further erosion issues.
