Geomembrane – MacLine® is a  very low permeability bituminous membrane liner or barrier

It is sheet with thickness ranging between 3.0 and 6.0 mm and width varying between 1 and 4 m, produced by working a molten mix (consisting of bitumen, plastomeric and/or elastomeric polymers and mineral fillers) and featured by extremely small permeability coefficients.

MacLine® GCL

Macline® GCL is a geocomposite consisting of a layer of bentonite encapsulated between two geotextile non-woven needle punched geotextiles. The three layers are then needle punched together for maximum performance under a wide variety of field conditions.

This integrated matrix of bentonite and needle punched fibres provides high shear strength and allows the GCL to offer low permeability even when installed in adverse conditions. MacLine® GCL has high internal shear strength characteristics for steep slope applications.
