Geosynthetic Clay Liner

Product introduction

Bentonite waterproof liner (GCL) is a new geosynthetic material. Taking natural sodium bentonite as material, bentonite particles are fixed between two layers of geotextile by special process to make bentonite waterproof blanket, which not only has all the characteristics of geotechnical materials, but also has excellent waterproof (seepage) performance.
Product features

· It has excellent water swelling property and strong compactness;

· Durable waterproof performance, green environmental protection;

. With the functions of separation, reinforcement, protection and filtration, the construction is simple.

Product specification
3OOOg/m²-6OOO0/m^z; Width: 3-6M

Notes
1 Bentonite property tests performed at a bentonite processing facility before shipment to INNO GCL production facilities.
2 Bentonite mass/area reported at 0 percent moisture content.
3 All tensile strength testing is performed in the machine direction using ASTM D 6768. All peel strength testing is performed using ASTM D 6496. Upon request, tensile and peel results can be reported per modified ASTM D 4632 using 4 inch grips.
4 Index flux and permeability testing with deaired distilled/deionized water at 80 psi (551kPa) cell pressure, 77 psi (531 kPa) headwater pressure and 75 psi (517 kPa) tailwater pressure. Reported value is equivalent to 925 gal/acre/day. This flux value is equivalent to a permeability of 5x10^-9 cm/sec for typical GCL thickness. Actual flux values vary with field condition pressures. The last 20 weekly values
prior the end of the production date of the supplied GCL may be provided.
5 Peak values measured at 200 psf (10 kPa) normal stress for a specimen hydrated for 48 hours. Site-specific materials, GCL products, and test conditions must be used to verify internal and interface strength of the proposed design.
