Water is Relentless!

Water is Relentless - Body

Water is relentless. This is a key fact that all waterfront property owners should thoroughly understand. The price of enjoying an oceanfront, riverfront, or lakeside view from the comfort of your own home is the inherent risk that comes with living right next to a large body of water.

Four Critical Warning Signs of Seawall Failure

If your residence is protected by a seawall, you should familiarize yourself with the four critical warning signs of seawall failure:

  1. Soil Depressions Near the Seawall
  2. Rust Stains on the Surface
  3. Movement or Shifting of the Seawall
  4. Cracks in the Concrete

Excessive rainwater or floodwater build-up on the landward side of the wall (usually resulting from an inadequate or clogged weep hole system within the wall itself) will put untenable hydrostatic pressure on the structure. This pressure can cause parts of the wall to move and/or crack. Once the concrete is broken, landward side water will pull soil from your property through the wall and into the water on the other side, causing depressions or small sinkholes near the structure. In addition, steel rebar or mesh inside the wall is exposed to rust, resulting in rust stains appearing on the surface.

Four Options for Dealing with Seawall Damage

Once aware of these problems, you’re faced with four options:

  1. Ignore the Problem and Do Nothing
    (If you go this route, the problem gets worse – and more expensive to repair – over time.)
  2. Replace the Seawall
    (This option is typically a lot more expensive than a repair, requires heavy equipment, and involves messy disruptive excavation.)
  3. Repair with Inferior Methods
    (Inferior repair materials such as hydraulic cement, slurry, and sodium silicate do not provide a permanent, long-term solution.)
  4. Repair with proven Seawall Repair Network® methods.
    (More on this in the next section.)

You can read more about these four options on the Seawall & Bulkhead Replacement vs Repair page. Needless to say, any of the four critical warning signs should warrant a checkup from a qualified seawall repair contractor. Most contractors offer free professional assessments and repair estimates.

Fortunately, there are many effective methods at your disposal in the battle against water’s relentless onslaught. Seawall Repair Network® preferred marine contractors provide two major types of repair – seawall stabilization and seawall preservation.

Seawall Stabilization

Stabilizing a cracked or shifting seawall is accomplished via these four methods:

  1. Stabilizing Soil and Sealing Leaks with SW-RP1
    (SW-RP1 repair material is stronger than crystalline bedrock and safe for the environment.)
  2. Installing a Hydrostatic Pressure Control System
    (Creation of pressure release channels with filters that allow water to move back and forth, maintaining an equilibrium of hydrostatic pressure. These filters also prevent soil migration and void formation on the landward side.)
  3. Repairing Cracks in Seawall Caps
    (Repairing the seawall caps with high-strength epoxy.)
  4. Installing a Seawall Anchoring System – If Necessary
    (When needed, steel tie-backs are installed to prevent future movement of the seawall.)

You can learn more about these methods on the Seawall Stabilization page.

Seawall Preservation

Treating the concrete with preservation solutions provides additional long-term protection. Preservation is accomplished via these three methods:

  1. Inhibiting Corrosion with SW-Prevent
    (SW-Prevent creates an insulating layer on the surface of any steel rebar or mesh inside the wall.)
  2. Strengthening Surface Concrete with SW-Power
    (SW-Power renders concrete surfaces resistant to air or water-born chemical damage.)
  3. Protecting  Surface Concrete with SW-Protect
    (SW-Protect inhibits water penetration.)

You can learn more about these methods on the Seawall Preservation page.

Water is Relentless – But YOU Can Be Too!

There is no reason to be intimidated by water’s relentless onslaught. All you have to do is memorize the four critical warning signs, and then enlist a qualified seawall repair contractor when needed. With the proper stabilization and preservation support, your seawall can safely protect that beautiful waterfront view for generations to come.

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.

SW-RP6: Seawall Repair Product for Stabilizing Surrounding Soil

In the blog article SW-RP6: Soil Stabilization for Seawall Repair we explain that “SW-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. SW-RP6 is phthalate-free and NSF certified to NSF/ANSI/CAN 61 (approved for contact with drinking water).”

Seawall Repair Products for Concrete Preservation

From Seawall & Bulkhead Concrete Preservation: “Concrete is chemically formed through a process known as hydration/curing.

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.
