Waste Not, Want Not
With proven waste containment technology, our Geosynthetic Clay Liners (GCLs) can protect against contamination from a wide spectrum of waste materials. With a full range of product formulations combined with our proven expertise, we engineer solutions customized for individual site requirements.
No matter your site challenges, CETCO can help you meet them.
Why geosynthetic containment systems?
GCLs can replace compacted clay in liner systems required in many regulations. They effectively minimize system leakage by providing "intimate contact" with the overlying geomembrane. This allows a GCL-based liner to outperform a compacted clay-based system. Another popular design option is to combine a geomembrane, a GCL and a partial thickness of a low permeability soil to maximize both hydraulic performance and puncture protection.
GCLs are increasingly being used as the sole hydraulic barrier for landfill caps in preference to geomembrane and compacted clay. They have good slope stability characteristics and do not require geotextile protection. They can be installed in less than perfect ground and weather conditions and often do not require the preparation of special subgrade and cover soils. GCLs are resistant to freeze/thaw, desiccation/rewetting and differential settlement, all of which can damage traditional compacted clay liners.
