nKlay – Geosynthetic Clay Liners (GCL)
nKlay – A Geosynthetic Sodium Bentonite Clay waterproofing Liner with consistent low
permeability and maximum performance under a wide variety of infrastructures.
Advanced Sealing Technology for Environmental Protection
nKlay is a high-performance Geosynthetic Clay Liner (GCL) that combines natural sodium bentonite clay with durable geotextiles to form a low-permeability barrier. It’s an ideal alternative to traditional compacted clay liners, offering faster installation, improved consistency, and superior containment capabilities.
Engineered for use in environmental containment applications, nKlay is widely trusted in sectors such as waste management, mining, water conservation, and industrial construction.
Why Choose nKlay?
✅ Superior Hydraulic Performance
nKlay creates an effective seal with extremely low permeability, preventing seepage and groundwater contamination.
✅ Cost-Effective Alternative
Reduces the need for transporting and compacting large volumes of clay, cutting installation time and overall project costs.
✅ Fast and Easy Installation
Pre-fabricated rolls make it easy to deploy over large areas quickly with minimal labor and equipment.
✅ Self-Sealing Capability
In the event of punctures or minor tears, the bentonite naturally swells upon hydration to seal the breach.
✅ Eco-Friendly
Made from natural materials and requiring less energy-intensive equipment, nKlay supports environmentally sustainable construction practices.

Installation Process
Site Preparation – Grade and compact the subgrade as per engineering requirements.
Roll Deployment – Unroll nKlay with minimal overlaps and avoid stretching.
Overlap and Seaming – Maintain proper overlaps (typically 300 mm); optionally seal with bentonite Powder or PU Sealant.
Protection Layer – Apply a cushion layer or ballast material (e.g., sand, soil, or geotextile) to prevent damage.
Sustainable, Reliable, and Easy-to-Install
nKlay offers a smarter, more sustainable way to create secure containment barriers. Whether you are building a new landfill, lining a pond, or protecting groundwater near an industrial facility, nKlay delivers efficiency, performance, and peace of mind.
