Seawall Repair

Protect and Reinforce Your Coastal Defense

Seawalls are a critical form of coastal defense, but they are not immune to deterioration. Reinforce your seawalls today with the expert help of Greenline Services.

Why Seawall Reinforcement and Repair Is Essential

Seawalls are constructed along the shoreline to separate the beach from the mainland, providing defense against powerful waves and preventing coastal erosion. However, over time, seawalls can deteriorate and fail due to various factors.

Causes of Seawall Deterioration

Erosion: The primary cause of seawall deterioration is the erosion of soil beneath or behind the wall. This erosion is often due to water infiltration from leaks or improper drainage, which can cause the seawall to break down or collapse.
Poor Compaction: If the soil was not properly compacted during construction, it could lead to settling or softening, resulting in erosion or voids.

Regular inspections are crucial to catching early signs of seawall failure, such as:

Addressing these issues promptly can prevent the need for more extensive and costly repairs.

Why Polyurethane Foam Is the Best Solution

When it comes to seawall repair, total replacement is the most expensive and disruptive option. It involves extensive excavation, creates a significant mess, and can disturb nearby properties. While necessary in some cases, most seawall issues can be resolved with less invasive methods.

Filling voids with dirt, aggregate, or cement grout is a temporary fix that doesn’t prevent further erosion. In contrast, using polyurethane foam offers a long-term solution. Polyurethane foam is lightweight, durable, and quick to harden, effectively permeating the soil to stabilize loose areas, fill voids, and seal failing joints. It also resists water erosion, making it ideal for seawall waterproofing at a fraction of the cost of total replacement.

Seawall Repair FAQ

How do you fix erosion behind a seawall?

Polyurethane foam injections are the best solution for fixing and preventing erosion behind seawalls. Polyurethane foam is durable, waterproof, and lightweight. Additionally, the foam we use is completely safe for contact with drinking water.

What is the best material to backfill a seawall?

Polyurethane foam is the ideal material for filling voids behind a seawall. It easily permeates the soil and is simple to install, effectively combating erosion and reinforcing the seawall.

How do you reinforce a seawall?

Greenline Services reinforces seawalls by injecting polyurethane foam into the soil. This process strengthens the support structure and effectively prevents erosion, ensuring long-lasting stability.

How long do concrete seawalls last?

Concrete seawalls generally last between 30 to 50 years. However, several factors can compromise their integrity and accelerate deterioration. Injecting polyurethane foam into the soil behind the seawall helps reinforce the structure and prevent further damage, extending its lifespan.

What is the life expectancy of a seawall?

The lifespan of a seawall depends on the material it’s made of. Concrete seawalls typically last between 30 to 50 years, while steel seawalls tend to last around 35 years.

How often do seawalls need replacing?

Seawalls will likely need extensive repairs or replacement around the 20-year mark if not properly maintained. The exact timing depends on the material of the seawall and the quality of its maintenance.

Why do sea walls fail?

The most common culprit of seawall failure is erosion. When water seeps into the wall and infiltrates the soil, the soil can lose its strength. Other contributing factors include long-term saltwater exposure, extreme weather conditions, and the natural aging process of the seawall.
