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.

Ayala Land Alviera Detention Pond
Philippines
The Ayala Alviera development in Pampanga faced increasing challenges related to stormwater management due to intense and unpredictable rainfall events. To prevent flooding in adjacent areas and protect infrastructure within the development, a detention pond was designed. However, it was critical to ensure that the stored stormwater would not infiltrate the subgrade, which could compromise the pond's holding capacity and affect nearby structures.

Bacolod Sanitary Landfill
Philippines
The City of Bacolod required a long-term and environmentally secure solution for its growing solid waste management needs. For the sanitary landfill in Brgy. Felisa, it was essential to implement an engineered containment system that would prevent leachate from contaminating surrounding soil and groundwater. The design called for a dual-liner system that would comply with environmental regulations and withstand the region’s climatic and geotechnical conditions.

MICOROSA ENVIRONMENTAL REMEDIATION PROJECT
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.
