MacLine® GCL is a high-performance geosynthetic clay liner engineered to deliver exceptional waterproofing and containment performance. When hydrated on site, MacLine GCL forms an extremely low-permeability barrier, making it an ideal solution for environmental protection, waterproofing systems, and geological containment applications.

Manufactured using advanced needle-punched composite technology, MacLine GCL consists of a premium sodium bentonite layer securely encapsulated between two durable geotextiles. This robust construction ensures long-term integrity, uniform hydraulic performance, and ease of installation, even in challenging site conditions.

To meet the demands of high-performance and aggressive environments, the bentonite and geotextile components can be precisely engineered to suit specific project requirements. For enhanced chemical resistance, durability, and ultra-low permeability, MacLine GCL composites can also be laminated with polymeric films or thin membranes, delivering superior performance for the most demanding containment and waterproofing projects.
