GCL
High-Performance Geo-Clay Liners for Low Permeability Barriers
Geo-Clay-Liners (GCL) are composite barriers created by encapsulating a bentonite layer between two geotextiles, typically through a needle-punching process. When hydrated, the bentonite expands to form a highly effective low-permeability lining system, ideal for creating geological barriers and waterproofing systems. These liners provide reliable protection in a variety of environmental and construction projects, where controlling water movement and contamination is critical.
Backed by Maccaferri’s decades of experience in geotechnical solutions, GCL can also be laminated with polymeric films or thin membranes to further reduce permeability and enhance durability for demanding applications. Whether it’s used in landfills, mining operations, or environmental containment, Maccaferri’s expertise ensures that GCL systems deliver long-term performance and reliability, offering the best in barrier technology for challenging conditions.

THE ASH YARD OF THE THERMAL POWER PLANT
The Punta Catalina thermoelectric power plant is the most important electricity generator in the Dominican Republic, as it produces 30% of the country's electricity. Its source of generation is coal, and as a byproduct of this process, residue known as ASH is produced. This ash is destined for confined cells due to its high content of heavy metals, preventing environmental damage to both the subsoil and the dispersal of volatile ashes in the air.

MICOROSA ENVIRONMENTAL REMEDIATION PROJECT
Italy
The Micorosa area, designated as a National Interest Site (SIN), posed significant environmental challenges due to the presence of an industrial waste landfill. The critical environmental levels in this SIN area necessitated a permanent security intervention. The project, authorized by the Italian Ministry of the Environment, aimed to address the persistent issues through capping and physical girdling using a plastic diaphragm.
