Geosynthetic clay liners (GCLs) can be considered as a relatively new technology that is able to form into a barrier mechanism and be applied in the anti-seepage projects of waste landfills. All of Tinhy’s Geosynthetic Clay Liners definitely conform to the U.S. standards for use in most countries and areas of the world. What’s more, the GCL technology can be used as an alternative plan that performs at or above the American performance levels.
Geosynthetic Clay Liners, for your information, is quick as well as simple to install, seize the positive traits of low permeability, and have the power of self-repairing against the holes that come from the swelling properties of sodium bentonite between the two sides of geotextiles or geomembranes.
GCL technology provides featured and unique advantages compared with those traditional anti-seepage methods. Besides, the cost of our Geosynthetic Clay Liners is quite reasonable in countries where conventional compacted clays are not available in use. A mature Geosynthetic Clay Liner system is not so thick as a compacted clay system, which makes engineers much easier to build landfills with maximum capacity while groundwater can be protected effectively.
As is known to all, sodium bentonite has the great absorbent ability to form grainy clay from the volcanic ash, which can attract water particles effectively and positively. Under this circumstance, the bentonite may quickly hydrate when exposed to water or leachate. Going with the hydration of clays, the ability to self-repairing rips or holes in the Geosynthetic Clay Liners can be given according to bentonite’s swelling features. In reference to our tests in the lab, Tinhy’s staffs found that a hole whose diameter is up to 75 mm will seal by itself, giving the Geosynthetic Clay Liner an access to hold the properties and effectively form into a barrier system.
