Liquid Containment

CETCO's Extensive Product Line Solves Any Site's Demands

With proven liquid and waste containment technology, our Geosynthetic Clay Liners (GCLs) can take on the challenges of any site. From bentonite-based GCLs to polymer-modified GCLs, our line is extensive and solutions customizable.


Your challenges are unique - and with CETCO, so is your solution.



Why geosynthetic containment systems?

Featuring our proprietary, high-density needlepunched construction, CETCO GCLs outperform compacted clay liners in both performance and ease-of-installation. GCLs provide significant advantages over compacted clay, including: 

  • Better hydraulic performance with less variability
  • Installed in wider temperature range and weather conditions
  • Faster construction times
  • Consistent, known and tested quality
  • Technical and design assistance
  • Reduced carbon footprint

Easily configured for a wide range of applications, GCLs provide increased durability and consistent performance and are increasingly replacing compacted clay liners in applications including:


GCLs are used for decorative ponds, golf course water features, fish ponds, water reservoirs, and wastewater lagoons. Their self seaming installation requires no specialized equipment, and their self-healing characteristics promote long life and high performance.



Composite laminated GCLs offer puncture and tensile strengths beyond conventional geomembranes. These GCLs offer the low permeability of a geomembrane combined with the high swelling and self healing characteristics of a traditional GCL. GCLs are often specified in canals, stormwater impoundments or wetlands to control seepage and conserve valuable water where native soils are too permeable.


Secondary Containment

GCLs are used around and underneath above ground petroleum storage tanks as secondary containment. Installation details and penetrations are easily handled, resulting in a cost effective installation.

Highway and civil

GCL can be used in highway and civil applications such as airport de-icing facilities used to remove ice build up on the surfaces of planes. During the application process, glycol-based de-icing fluids can leak into local stormwater runoff, potentially causing pollution. CETCO GCLs were found compatible with de-icing fluid (glycol diluted 50/50 with water). GCLs can also be used to line roadway drainage swales for containment and prevent excessive percolation, thereby minimizing potential for groundwater contamination. Another example of using GCLs in civil and highway applications is using the liner to contain acid rock and prevent runoff from entering the local water supply.
