Coastline and Beach Erosion Control
Products to Help with Beach Erosion
Beach erosion has become a headline issue as it continues to be a growing problem on coastlines around the world. Whether the shore is sheltered or exposed, elements like currents, waves, and sea level changes play significant roles in causing erosion. As a solution-based provider, GEI Works offers several different products to help control coastline erosion and prevent further deterioration along your shores. Read on for several different beach erosion solutions, or contact one of our specialists to help you determine which method is best for your coastline erosion application.

Erosion Control Mats
Erosion control mats are sometimes an option for areas around shorelines or beaches. Mats are typically designed to further the growth of vegetation by stabilizing an area long enough for plants, trees, and roots to establish themselves within the area. Mats are made from biodegradable, natural fibers such as coir, straw, and wood fibers.
Breakwater Tubes are commonly used for long, demanding, or extended shoreline support. Once installed, tubes act as a first layer of defense against waves as they break along the shore. This allows the beach to naturally retain sand and helps limit the deterioration of the shoreline.
If your area is implementing the use of retaining walls, rip rap or larger structures, using a geotextile under these products can help increase stabilization and strength. Due to the heavy nature of these items, the most commonly implemented fabric is a woven geotextile.
Coconut Fiber Logs
The coconut fiber log is another natural fiber product designed to help with erosion control along beaches. Logs can be implemented in sand dunes or in revegetation areas to help establish roots.
Earth Barrier Walls
Self-erecting bags are an excellent stabilizing barrier for coastal restoration projects. These rapid-deployment bags are a sustainable leave-in-place or temporary solution. Protecting dunes, rebuilding coastal shorelines, or preserving beaches are a concern for beachfront commercial and residential property owners. The earth barrier walls fold out accordian-style and provide solid defense against incoming tides and wave action. The bags are covered up with sand to create a solid beach infrastructure.
Popular Beach Restoration Options
One of the most popular solutions to beach erosion issues is something known as beach restoration or beach nourishment. However, this is not only a temporary solution, but it is also a controversial subject. Sand must be trucked in from other sources and filtered for sediment. The new sand will also eventually make its way into the air or water, bringing the beach back to its eroded state.
Another popular solution is to build seawalls, revetments, and jetties along the shoreline. According to Dr. Ken Ruben , assistant professor of Geology and Geophysics at the University of Hawaii, "[t]hese have a negative effect on beaches because once sea water reaches them, it bounces off them with more energy than a wave washing back off a normal sand beach."
Good Long Term Solutions
So what is a good solution? Nothing beats beach erosion like natural vegetation. Natural fibers, like coir, can help propagate the growth and provide stability to root systems. If a seawall must be built, the fabric underlay should be a geotextile. See our 7 Simple Water Pollution Solutions.
