Bentofix® BFG 5000
Bentofix® BFG 5000 is a Geosynthetic Clay Liner (GCL) of a continuous layer of a high swelling sodium bentonite powder, sandwiched between a needle-punched polypropylene (PP) geotextile as a cover layer and a slit-film PP woven geotextile as the carrier layer. The components are needle-punched uniformly together across the entire GCL creating a shear stress-transferring composite GCL. Additional 800g/m² bentonite with the same quality as the core bentonite is impregnated into the entire cover nonwoven geotextile during the manufacturing process to facilitate self-sealing overlaps. An overlap guide-line delineating the overlap zone is imprinted with non-toxic ink 30cm from the woven edges of the GCL panel to ensure the accuracy of the seam.
