Geosynthetic Clay Liner vs. Compacted Clay
Geosynthetics have gained widespread popularity in civil, geotechnical, environmental, coastal, and hydraulic engineering projects owing to their versatility and cost-effectiveness. Of note, over the past decade or so, Geosynthetic Clay Liners have replaced compacted clay liners in various applications, especially in terms of hydraulic performance and ease of installation. The Ocean Geosynthetics, prefabricated geosynthetic clay liners, find immense uses as cover systems, composite liners, protection barriers, storage tanks, canal liners, pond liners, and more. www.oceangeosynthetics.com

What is unique about the Ocean Geosynthetics Prefabricated Geosynthetic Clay Liners? The Ocean Geosynthetics’ prefabricated geosynthetic clay liners consist of high-quality bentonite liner encapsulated between two layers of geotextiles needle punched

and then subjected to controlled heat treatment to thermally lock the layers and fibers in place, providing high shear strength. They find use as single or composite liners. The benefits of compacted clay:

Here are some reasons why GCLs are largely replacing traditional compacted clay. Natural sealant: The sodium bentonite characteristically swells on wetting with an affinity for water, acting as a sealant around penetrations, selfhealing punctures, and also self-seam at overlaps. Long-term performance: GCLs eliminate the problems of differential settlement and are less impacted by desiccation-rewetting cycles owing to the high plasticity and self-healing capabilities of sodium bentonite. The traditional compacted clay liners succumb to these conditions and crack up. The GCLs are invariably more resistant to varying weather conditions providing consistent performance over the long-term. The compacted clay liners, on the other hand, show a decrease in performance with varying moisture content, clay content, or density and are hugely dependent on weather conditions. www.oceangeosynthetics.com
