Finesse Alphaline geomembranes are manufactured from high quality virgin Polyethylene (PE) and Polypropylene (PP) in a quality controlled environment.

Finesse Claymat is a Geosynthetic Clay Liner (GCL). Sodium bentonite has long been recognised as the ideal impermeable barrier material. Finesse Claymat provides this in a convenient sandwich between two layers of geotextile. The result is a thin, flexible, clean, easily transported and installed lining system.

In many applications the performance of the Alphaline and Claymat is enhanced by the associated specification of the geocomposite drainage and protection layer Finesse Pozidrain.
