Arcosa Lightweight’s expanded shale and clay aggregates provide a sustainable solution for coastal restoration, effectively stabilizing shorelines, reducing erosion, and promoting sediment buildup to restore marshlands.
By using lightweight aggregate-filled geotextile bags, Arcosa helps protect sensitive coastal areas from wave impact, while supporting ecosystem regrowth and resilience against tropical storms.
Arcosa Lightweight aggregates provide stable, eco-friendly solutions for coastal restoration, reducing shoreline erosion, supporting sediment buildup for habitat restoration, and withstanding harsh marine conditions.
Arcosa’s lightweight aggregates dissipate wave energy, reducing shoreline retreat and protecting coastlines. This stabilizing effect is critical in areas with significant erosion challenges, helping maintain shoreline integrity.
The porous nature of Arcosa aggregates encourages sediment buildup, fostering habitat creation and regrowth in marshes and other coastal environments. This supports biodiversity and helps restore ecological balance in sensitive coastal regions.
Lightweight aggregates reduce overall project costs by minimizing material settlement, allowing for cost-effective use of resources. The non-toxic, non-degradable composition of Arcosa aggregates also ensures environmental safety and longevity.
In January 2021, Civil Engineering, the magazine of the American Society of Civil Engineers (ASCE), published a thorough article about the massive land-saving project along the 26.5 mile section – with an emphasis on a specific 9.2 mile stretch of marshland – bordering the Gulf of Mexico in Cameron and Vermillion Parishes.

Arcosa aggregates help absorb and disperse wave energy, preventing soil loss and stabilizing coastal areas effectively.
The porous structure of the aggregates promotes siltation, creating a foundation for marsh and habitat restoration in coastal regions.
Easy to transport and install, Arcosa’s aggregates provide a low-maintenance, long-lasting coastal solution, especially suited for areas where traditional rock breakwaters are impractical.
