Strong and Durable Seawall Repair Material

Body - Strong and Durable Seawall Repair MaterialSeawall Repair Network member contractors using SW-RP1 repair material provide superior results and permanent solutions for waterfront property owners. Simply put, SW-RP1 is the strongest and most durable product currently in use for seawall and bulkhead stabilization.

The Installation Process

Proper installation of SW-RP1 is essential for sealing cracks, filling voids and repairing defects behind a seawall, and – perhaps most importantly – stabilizing the supporting soil. Once installed, SW-RP1 transforms the soil into a water-tight impermeable mass. This, along with the installation of dewatering channels with panel filters, relieves lateral stress caused by the typical build-up of hydrostatic pressure behind the seawall.

Environmental Safety

SW-RP1 is environmentally safe and is certified to NSF (61-5) standards for contact with drinking water.

Strength and Durability

One detail that cannot be emphasized enough is the strength of the material. Once SW-RP1 cures, it is stronger than crystalline bedrock. Originally seen in the blog post, SW-RP1 – Rock Solid Seawall Repair Material, this video demonstrates the strength of the materials once cured…

Body - Using Seawall Repair Network Stabilization Methods in New ConstructionIn addition to repairing seawalls, Seawall Repair Network member contractors can also provide permanent soil stabilization and hydrostatic pressure regulation for newly constructed seawalls and bulkheads. Landward-side soil migration, erosion, void formation, and the build-up of hydrostatic pressure cause structural movement and damage to a seawall. It’s important for property owners, contractors, and engineers to understand that permanent seawall stability can be achieved at the time of initial construction. The stabilization process during new construction involves the installation of  SW-RP1, and de-watering channels with panel filters. This process significantly improves the overall engineering design, durability, and lifespan of seawall structures.

By making these simple changes to the new seawall construction process, the Seawall Repair Network member contractor will:

  1. Provide a permanent solution to the most pressing problem associated with seawall construction – long-term soil stability.
  2. Position the new-construction contractor to provide meaningful warranties for installation and materials.
  3. Help new-construction contractors provide waterfront barrier systems that are reliable.
  4. Contribute to a superior seawall construction industry.

Environmentally Safe Seawall Repair

Body - Environmentally Safe Seawall RepairDo not get caught off guard. It’s crucial to determine if the seawall contractor you are considering uses repair materials that meet NSF/ANSI/CAN 61 standards for contact with drinking water. But what exactly are NSF/ANSI/CAN 61 standards? Our goal here is to provide a concise and comprehensive overview of why NSF approval is important for any materials that may be used to repair your seawall.

What is the NSF (National Sanitation Foundation)?

The National Sanitation Foundation develops public health standards and certification programs that help protect the world’s food, water, consumer products, and environment. Their organization ensures that adequate testing is conducted for all products that will be used in or around drinking water from source to tap.

As mentioned in our blog post, SW-RP1 – Environmentally Friendly Seawall Repair Material

An NSF compliance brief reads: “NSF, an independent, private, not-for-profit, third-party certification organization founded in 1944, has developed numerous health-based certification programs and consensus standards including those that relate to drinking water…The purpose of its certification program is to promote public health and enrich the quality of life. Through its Council of Public Health and Health Advisory Board, which includes EPA health professionals, it obtains guidance in developing and maintaining programs and standards. NSF also partners with code councils to ensure ongoing compliance.”

Each product must undergo rigorous testing to receive NSF approval. The manufacturer’s plant and quality assurance practices must pass a thorough inspection. Voluntarily undergoing such a rigorous certification process is invaluable to all parties involved.

The SDWA (Safe Water Drinking Act)

As mentioned in our blog post, SW-RP1 – Environmentally Friendly Seawall Repair Material

The Safe Water Drinking Act (SDWA) gives the EPA latitude to impose criminal and civil penalties on industries that are not in compliance. In 2014 enforcement efforts policing clean water netted $163 million in penalties and fines, 155 combined years of incarceration for sentenced defendants, and $16 million in court-ordered project clean-ups.

Because so many of those defined contaminants are pertinent to even the most basic construction projects – turbidity from soil runoff, leaching from PVC pipes, potentially harmful and corrosive chemicals, and more – understanding and adhering to the law is particularly important for industry stakeholders. Contractors and engineers must be able to confidently choose vendors whose products and services won’t become the source or cause of drinking water contamination either in the short or long term.

Using products certified to NSF/ANSI/CAN 61 (approved for contact with drinking water), ensures compliance with the SDWA.

The Disadvantages of Filling Seawall Voids with Cement (or How to Repair a Seawall)

Body - The Disadvantages of Filling Seawall Voids with Cement (How to Repair a Seawall, How to Repair a Bulkhead)Many Contractors Still Do Not Know How to Repair a Seawall

Before the advent of advanced seawall repair materials such as SW-RP1, contractors often attempted to fill voids behind seawalls with cement (which cures into concrete). Unfortunately, there are still inexperienced contractors out there who are using this outdated method.

The Disadvantages of Filling Seawall Voids with Cement

Concrete Puts Unnecessary Pressure on the Seawall and Surrounding Soil: Concrete weighs a lot. Filling a void behind a seawall with cement creates additional lateral load pressure on the seawall. The heavy concrete also further destabilizes the soil over time.

Concrete Displaces Supporting Soil and Breaks Apart Over Time: Unlike our SW-RP1 seawall repair material, cement does not permeate and stabilize loose soil surrounding a void. Instead, cement just displaces the surrounding soil. This leaves open the possibility of further erosion and void formations below and around the cured concrete. Once the surrounding soil begins to give way, the concrete will often break into pieces over time (see the featured photo in this blog post for an example).

Concrete in the Soil Impedes Advanced Seawall Repair Methods: Since void-fill with cement is not a lasting solution for seawall-supporting soil, proper repair with advanced materials such as SW-RP1 will eventually be required. Unfortunately, concrete in the soil surrounding the wall just makes this process slower and more expensive. Concrete in the soil obstructs advanced seawall stabilization methods such as installing repair material via injection rods and installing an anchoring system. In a case like this, additional time and resources would be required to excavate and dump the old void-fill concrete, then replace it with fresh fill soil before beginning the repair process.

So consider yourself warned if a contractor proposes filling the voids behind your seawall with cement. What once (long ago) may have seemed like a common-sense solution has been repeatedly proven to make the situation worse over time.

Seawall Repair Network’s Patent-Pending Process

Body - Seawall Repair Process Seawall Stabilization What Causes Seawall Failure

Mother Nature’s oceans, lakes, and rivers can be so beautiful and calm. But over time, her natural forces will cause damage and eventual failure of your seawall. Seawalls are complicated structures made up of a variety of essential components. If one component fails, the entire seawall is at risk. In traditionally constructed seawalls, weep holes with a geotextile fabric filter allow water to flow from the landward side back into the ocean to prevent pressure build-up.

What Causes Seawall Failure?

What causes your seawall to fail? Over time, as the filter fabric fails, soil migration creates voids behind the wall, which causes structural instability. As the voids behind the wall fill up with water, hydrostatic pressure behind the seawall causes the wall panels to shift over time. The shifting panels damage the seawall cap, which holds the entire structure together. When this happens, failure of the seawall is imminent. If ignored, these problems only get worse.

Body - Seawall Repair Northeast Bulkhead Repair in the Northeast Seawall Repair Options

Many seawalls along the northeastern United States are in a state of disrepair, for a wide variety of reasons. Rising water levels, corrosion, seasonal freeze/thaw cycles, storms, and extreme weather events all contribute to seawall deterioration over time. Properly built seawalls include a drainage system to handle the daily influx and outflow of water from rain, tides, and waves. Over time, these drainage systems can sometimes become clogged. Seawalls without an effective built-in drainage system face a unique problem in that the water has no way to escape except to force its way down and out from underneath the base of the wall. When this occurs, sinkholes will appear alongside the wall.

Seawall Repair Options

Property owners facing seawall deterioration have a few options:

  • Do Nothing: The problem with this option is obvious – the longer you wait, the more expensive the eventual repair.
  • Replace the Seawall: Rebuilding a seawall (or even a section of a seawall) can be messy, time-consuming, and expensive.
  • Repair with Cement Grout: Cement grout seawall repair requires heavy equipment, large drill holes, and the use of weighty cement grout which may sink over time.
  • Repair with Seawall Repair Network: Seawall Repair Network’s repair process is accomplished with small mobile equipment, proprietary SW-RP1 durable repair material that doesn’t sink, and small drill holes. This procedure is less messy and more efficient than replacing the seawall or repairing it with cement grout.

Seawall Repair Network’s SW-RP1 is stronger than crystalline bedrock. Combined with proper drainage, seawall repair with SW-RP1 can greatly extend the life of the structure.

Seawall Repair on Lakefront Properties

Body - Lakefront Seawall Repair Lake Bulkhead Repair Signs of Seawall DistressSigns of Seawall Distress

Do you own or manage lakefront property? If so, you may have issues with your seawalls. Check for the following danger signs:

  • Settled soil near the wall (a sign of water leaking through the wall and eroding the soil on the land side).
  • Soil deposits near the seams on the waterside of the wall (a sign of water leaks bringing soil through the seams into the lake).
  • Visible rust-colored cracks or stains in the wall (a sign of water leaking through cracks in the wall and rusting the rebar inside).

SW-RP1 for Lakefront Seawall Repair

High-strength SW-RP1 repair material can be injected through pipes directly into voids and loose soil around your distressed seawall. Seawall Repair Network contractors use material that reacts with moisture in the ground and expands to fill voids while also permeating the soil to form a solid, strong, watertight mass.

Since SW-RP1 is impermeable to water once in place, the likelihood of future erosion is vastly diminished versus refilling the void with other material. This technology has one of the strongest histories of success in the field.

Efficient seawall repair with this material prevents the need for remediation processes that can be harmful to the environment, such as a complete wall replacement or the excavating of all loose soil. SW-RP1 is approved for contact with drinking water once cured in place. So you don’t have to worry any long-term negative environmental impact.
