Hot New Products Bentomat Gcl - Clay Geosynthetic Barriers – Yingfan Detail:
Product Description
We, Shanghai Yingfan Engineering Material Co., Ltd., is a clay geosynthetic barriers manufacturer in China. This product is also called “geosynthetic clay liner” (GCL), “clay blankets”, “bentonite blankets”, “bentonite mats”, “prefabricated bentonite clay blankets” and “clay geosynthetic barriers”, the latter currently favored by the International Organization for Standardization (ISO).
Clay Geosynthetic Barriers Introduction
It is bentonite geo-synthetic waterproofing barrier that often replaces thick layers of expensive compacted clay.
It is sandwich-made of a non-woven geotextile, a natural sodic bentonite layer and a polypropylene woven sheet.
Due to the hydro-expansive characteristic of bentonite (Bentonite composed predominantly (>70%) of montmorillonite or other expansive clays) and the needle punching method of manufacture which gives the resulting composite material shear strength, a critical feature for installation on slopes, our clay geosynthetic barriers can be used in many erosion control requested civil engineering.
Its performance can meet or exceed GRI-GCL3 and our national standard JG/T193-2006.
| Differences between clay geosynthetic barriers and compacted clay liners (CCL) | ||
| Characteristic | Clay Geosynthetic Barriers | Compacted Clay Liners (CCL) |
| Material | Bentonite clay, adhesives, geotextiles | Native soils or blends of soil and bentonite clay |
| Construction | Factory manufactured and then installed in the field | Construction and/or amended in the field |
| Thickness | ~ 6 mm | 300 to 900 mm |
| Hydraulic conductivity of clay[7] | 10−10 to 10−12 m/s | 10−9 to 10−10 m/s |
| Speed and ease of construction | Rapid, simple installation | Slow, delicate and complicated compaction works |
| Installed cost | $0.05 to $0.10 per m2 | Highly variable (estimated range $0.07 to $0.30 per m2) |
| Experience | Construction quality assurance and quality control are critical | Highly workforce dependent |
