Bentonite Mat /Geosynthetic Clay Liner-GCL

PTT CHINA is the earliest manufacturer of exporting bentonite mat GCL in China. We start this business from year of 2003.

 

We only produce top quality GCL, GTL ( HDPE Geomembrane laminated GCL) by top quality of sodium bentonite granules or powder, woven and nonwoven geotextile.

 

As you may know, there are a lot of factories to produce GCL at cheap price in China. But We PTT CHINA are different. Our goal is to offer our client reasonable price with the best quality of bentonite membrane.

 

In the meantime, PTT machine engineer have developed special instrument to treat GCL to improve GCL’S peeling strength largely.

 

Small and large packing of GCL both are available for us.

It’s welcome to contact us for inquiry!

 

INTRODUCTION of PTT BENTONITE MAT GCL

 

Geosynthetic Clay Liners (GCLs) are geotextile and bentonite composites (typically sodium bentonite sandwiched between two layers of geotextile) engineered for a variety of environmental containment applications. The geotextiles offer a long lasting resistance to physical or chemical break-down in harsh elements, while the bentonite’s high swelling capacity and low permeability provide an effective hydraulic seal.

 

GCLs provide an excellent alternative to conventional Compacted Clay Liners by replacing a thick section of compacted clay with a thin layer of pure sodium bentonite. Benefits include easy installation, better hydraulic performance and resistance to varying weather conditions. Installation for most GCL projects can be completed by construction personnel using conventional equipment. GCLs also have unique self-sealing attributes, reducing the risk of failure due to adverse field and operating conditions.

 

TYPICAL LINING APPLICATIONS INCLUDE:

Canals, stormwater impoundments and wetlands

Secondary containment

Highway and civil

Landfill liners

Landfill caps

Mining

Ponds
