Differences Between Geosynthetic Clay Liners and Compacted Clay



Geosynthetics are widely used in civil, geotechnical, environmental, coastal, and hydraulic engineering projects because they can be used in many different ways and are inexpensive. Notably, Geosynthetic Clay Liners have replaced compacted clay liners in many applications over the past ten years or so, especially when it comes to hydraulic performance and how easy it is to install. Geosynthetic clay liners that have already been made, like Irk Geo Vision Geosynthetics, have a wide range of uses. They can be used as cover systems, composite liners, protection barriers, storage tanks, canal liners, pond liners, and more. We are Clay Liner suppliers with better quality offerings and affordability for your business. 

Because building infrastructure is becoming more important, the market for geosynthetic clay liners is growing and expanding quickly. Geosynthetics are also becoming more popular in the global geosynthetics market because people are becoming more aware of how safe they are for the environment. Irk Geo Vision is also among Geocell Suppliers in business. 

What’s a Geosynthetic Clay Liner?

Geosynthetic clay liners are made up of a layer of sodium bentonite clay and two layers of geotextiles. For strength, the geotextiles are needle punched, physically bonded, or stitched. They can be woven or nonwoven, depending on what the project needs and how they will be used.

Either polypropylene or bentonite is used to make the GCLs. Bentonite is a fine-grained clay that absorbs water. It is usually made of montmorillonite and gets bigger when it gets wet. In the geosynthetics industry, they are used for roads, railroads, waste treatment, landfill mining, gas and vapor seals, ground engineering, agriculture, waterproofing, tunneling, and so on.

What makes Our Geosynthetics Prefabricated Geosynthetic Clay Liners different?

Prefabricated geosynthetic clay liners from Irk Geo Vision Geosynthetics are made of a high-quality bentonite liner that is sandwiched between two layers of needle-punched geotextiles. The layers and fibers are then put through a controlled heat treatment to lock the layers and fibers in place, giving them a high shear strength. They can be used as single-liners or as part of a group.

Why Geosynthetic Clay Liners are Better than Compacted Clay:

Here are a few reasons why GCLs are replacing traditional compacted clay in most places.

Natural Sealant: 

Sodium bentonite tends to swell when it gets wet because it likes water. It acts as a sealant around holes, heals punctures on its own, and sews itself together where it overlaps.

Long-Term Performance: 

Because sodium bentonite is so flexible and can heal itself, GCLs don’t have problems with uneven settlement and are less affected by cycles of drying and rewetting. The traditional liners, which are made of compacted clay, can’t handle these conditions and crack. The GCLs are always more resistant to different weather conditions, so they work the same way over time. On the other hand, the performance of compacted clay liners decreases with changes in moisture content, clay content, or density. Their performance also depends a lot on the weather.

Ease of Construction and Installation: 

GCLs are better for the environment because they are easier to set up and use fewer natural resources. They also take up less air space. They are even easier to deliver than clay because all you have to do is unroll them and put them on top of each other, instead of hauling, dumping, spreading, and compacting the clay, which takes more time, requires more logistics, and costs more. Clay liners are made with local aggregate, but GCLs are made in factory units, where the quality of the raw materials and finished products is tested in a very strict way during and after production.
