GCL

GCL (Geosynthetic Clay Liner)

GCL it is an impermeable, reliable barrier, as well as fast and efficient.

We manufacture GCL (Geosynthetic Clay Liner) with an annual production capacity of 10,000,000 m², offering different configurations tailored to each project: woven or nonwoven top and bottom layers, variable weights, and dimensions adapted to each application.

Our GCLs combine high-performance impermeability, ease of installation, and chemical resistance, making them a competitive solution compared to traditional sealing systems such as compacted clay or geomembranes.

Key Advantages

1. High-performance waterproofing

Thanks to its natural sodium bentonite core, GCL provides extremely low permeability levels.
When activated upon contact with water, it forms a continuous and flexible seal.
Ideal as a primary or secondary hydraulic barrier.

2. Simple and fast installation

Supplied in ready-to-install rolls with predefined overlaps.
Does not require heavy machinery or highly specialized labor.
Significantly reduces construction time and overall logistics.

3. Self-healing capability

The bentonite expands and self-seals in the event of minor punctures, providing an added layer of safety against localized damage.

4. Chemical resistance and long-term stability

Maintains its properties when exposed to aggressive leachates, saline solutions, and extreme pH conditions.
Ensures long-term stability even in buried environments or in the presence of contaminants.
