Products to Help with Beach Erosion
Beach erosion is a common problem on developed 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 solutions-based provider, we offer 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 and erosion control products are best for your coastline erosion application.

Erosion control mats (also called blankets) can be an economical temporary option for areas around shorelines or beaches. Mats are typically designed to provide support for new vegitation that will help stabilize and protect the shoreline in the long run. By the time the natural fiber erosion control mat biodegrades, enrichiing the soil as it does, the plants and trees have become fully established. Mats are made from biodegradable, natural fibers such as coir, straw, and wood fibers.
Geotextile reakwater Tubes are used for shoreline support in areas that are exposed to harsh waves, currents, and windt. Once installed, tubes act as a first layer of defense against waves as they break along the shore. This protects the bank or beach 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.
The coconut fiber log is a biodegradable 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 made from self-erecting bags are a practical solution as a 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. Eearth barrier walls provide a 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.
