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.

Seawall Repair Network NSF Approved Solutions

Seawall Repair Network contractors use the following NSF-certified materials:

SW-RP6: Soil Stabilization for Seawall Repair

Body - SW-RP6- Soil Stabilization for Seawall RepairSW-RP6 is ideal for stabilizing soil around ancillary structures during the seawall repair process. This comes into play with buildings, parking garages, roadways, and other infrastructure in close proximity to seawalls with soil loss and settlement. In cases like this, the Seawall Repair Network contractor essentially creates chemical grout columns to provide stability.

Environmentally Friendly Seawall Repair Material

SW-RP6 is phthalate-free and NSF certified to NSF/ANSI/CAN 61 (approved for contact with drinking water).

Low Viscosity, Durable Seawall Repair Material

SW-RP6 is a single component, moisture activated, hydrophobic, extra-low viscosity soil grout. Once it permeates the soil and cures, the resulting mass is incredibly strong.

Watch the demo video below, in which SW-RP6 is mixed, permeates sand, and cures to a strength greater than crystalline bedrock.

In the blog post What is SW-RP1? Why Do You Need It for Seawall & Bulkhead Repair?, we posted the following info about SW-RP1…

The hallmark of the Seawall Repair Network is our proprietary SW-RP1 repair permeation solution. Simply put – it is the best product on the market for seawall soil stabilization.

  • SW-RP1 is essential for sealing your seawall’s panel cracks, filling voids and defects behind your seawall, and perhaps most importantly, proving soil stabilization for your seawall.
  • SW-RP1 transforms the surrounding soil of your seawall into a water-tight impermeable mass, which blocks the transference of energy and lateral stress caused by the typical build-up of hydrostatic pressure behind the seawall.
  • SW-RP1 is environmentally safe and is certified to NSF (61-5) standards for contact with drinking water.

Repairing a Seawall with High-Strength Material

One detail that cannot be emphasized enough, however, is the strength of the material. Once SW-RP1 cures, it is stronger than crystalline bedrock. Watch the brief video below for demonstrations of the injection process and the strength of SW-RP1 in cured form.

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.

Environmentally Safe Seawall Repair in the Northeast

Seawall Repair Network’s SW-RP1 has received the official NSF seal of approval for contact with drinking water (this also protects water-dwelling wildlife as well). This designation ensures compliance with the Safe Water Drinking Act (SDWA) and guarantees peace of mind for property owners and propery managers.

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.

Advanced Seawall Repair for Better Results

Body - Advanced Seawall Repair Seawall Deterioration Leaking SeawallsLet’s take an in-depth look at the installation of Seawall Repair Network’s SW-RP1 repair material vs alternative repair options. This process consists of stopping high flow leaks, filling the voids behind concrete structures, and binding loose soil with Seawall Repair Network’s SW-RP1 repair material.

The Problem – Leaking Seawalls

As tidal flows rise and fall, water pushes its way in through cracks, joints, and defects in seawalls. The water pushes in on incoming tides and flows out on outgoing tides. As the water flows out, it carries sand and soil with it, which causes voids to form in the supporting soil, undermining the structural integrity of the seawall. This cycle is exacerbated during periods of heavy rain which continue the outflow of soil.

The Evidence – How to Spot Seawall Deterioration

In landscaped areas, evidence of soil erosion is often quite obvious. You’ll often see small sinkholes developing near the seawall. It’s important to inspect closely underneath tall grass and shrubbery since foliage can sometimes obstruct your view of the damage. Other clues include cracks in concrete slabs near the seawall and piles of sand building up at the base of the seawall on the waterside (if you can manage to get an underwater view). If you’re still not sure, you can use a soil probe to get a feel for the condition of the soil near the seawall.

The Options – Seawall Repair Methods

When it comes to repairing a seawall, you have three main options:

Replace the Seawall

You can tear out the wall (or part of the wall) and replace it. This approach has a few daunting downsides…

  • Costs more than repair.
  • Takes up a lot of time.
  • Requires permits.
  • Disrupts the site and poses a risk to nearby structures.

Paying for a new seawall is no doubt going to cost more than any kind of repair. A complete rebuild will also take some time. Not to mention the inevitable mess, a good portion of which is likely to end up in the water. The excavation also requires getting a permit, which can eat up a LOT of time.

Repair with Cement Grout (Hydraulic Cement & Slurry)

Some contractors and property owners are still filling sinkholes and trying to plug seawall leaks with concrete. This outdated approach has many disadvantages when compared to Seawall Repair Network’s advanced SW-RP1 material…

  • Requires a lot of labor and machinery.
  • Takes up a lot of time.
  • Uses a repair material that is prone to degradation over time.
  • Adds unnecessary weight to a seawall that is already under stress.

The amount of labor and machinery required can be quite disruptive. Compared to the surgical approach of installing SW-RP1 repair material, the installation of cement grout can create quite a mess. Needless to say, with all this extra material, machinery and labor – the whole process takes a lot longer than your typical Seawall Repair Network job. Cement grout is known to shrink and degrade over time. Imagine the frustration of paying for an expensive seawall repair, only to see it wash out eventually. And cement that doesn’t wash out can add weight to the structure, causing the surrounding soil to sink again over time.

Repair with SW-RP1

Seawall Repair Network’s SW-RP1 is the proven next-generation technology for effective and long-lasting seawall repair. SW-RP1 offers the following advantages over both excavation and cement grout…

  • Causes minimal disruption (less labor, equipment, and material required).
  • Takes up less time (rapidly installed, with a quick return-to-use period).
  • Does not degrade over time.
  • Won’t’ cause soil to sink (lightweight high-strength material).
  • Does not harm the environment (NSF approved for contact with drinking water).

Compared to the typical excavation or cement grout repair crew, a Seawall Repair Network crew will seem like a stealthy ninja strike force. This non-invasive, clean approach to repair allows the property owner to continue using the surrounding area during the process. The property owner can resume activity directly on and directly next to the structure within hours after a repair. Cured SW-RP1 repair material has been rigorously tested for contact with drinking water. So there is no concern about ensuing environmental issues.

That’s why Seawall Repair Network’s SW-RP1 high-strength repair material has the official NSF seal of approval for contact with drinking water. This single designation ensures compliance with the Safe Water Drinking Act (SDWA) and guarantees peace of mind for property owners and managers.

The SDWA helps ensure the water we drink, bathe in, cook with, and use in myriad other ways in daily life is safe for consumption. The federal law was put in place to maintain public health standards for drinking water systems. It defines what is considered a contaminant – both man-made and naturally occurring; and outlines the agencies responsible for regulating, monitoring, and enforcing adherence to the law, primarily the Environmental Protection Agency.

The SDWA gives the EPA latitude to impose criminal and civil penalties on industries 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. NSF certification offers assurance that such problems won’t occur or will, at a minimum, be addressed.

“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,” reads an NSF compliance brief. “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.”

NSF-certified materials are evaluated and lab-tested, and production facilities such as our own are inspected and annually audited for re-testing to maintain certification.

Seawall Repair Network voluntarily undergoing such a rigorous certification process is invaluable to property owners and managers because it provides assurance that, at the end of the day, your seawall repair project is safe and environmentally friendly.

When you find yourself engaged in a search for seawall repair or replacement options, it’s fueled by the understanding that your seawall is key to preventing serious damage to (or even destruction of) your house, building, or property in general.

Unfortunately, most waterfront property owners have not been educated regarding replacement and repair with subpar methods:

  • Seawall replacement can be very expensive, disruptive, and sometimes even destructive to surrounding property.
  • Subpar, ineffective solutions such as hydraulic cement, slurry, crushed seashells, and sodium silicate do not address the underlying soil instability that puts unsustainable pressure on the seawall.  These methods are similar to putting a band-aid on an infection. The problem will simply continue to get worse until the seawall fails completely.
