Product Description

Product Introduction
Sodium bentonite geosynthetic clay liner (GCL) is a new type of geosynthetic materials.It is a blanket waterproofing material, which take a natural grading sodium base bentonite particles and corresponding admixture mixed as raw material, through the acupuncture technology and equipment, fixed bentonite particles between geotextile and plastic woven cloth. It has all the characteristics of geotechnical material, but also has excellent waterproof, seepage control performance.

Product Properties
Compared with the compacted clay liner, it has small volume, light weight, flexibility, good sealing performance, high shear strength, simple construction and adapt to uneven settlement, etc.

Product Application
Mainly used in environmental engineering constructions, such as waste landfill, underground reservoir, underground infrastructure construction projects, to solve the seal, isolation, seepage control and related problems, good effects and strong destruction resistance.

Product Specification
Unit Weight: ≥4000g/㎡ Width: 4m~6m *Roll Length: PS: Customized request accept for all above.
