GSE BentoLiner geosynthetic clay liner uses highswell
sodium bentonite encased in a needle-punched
nonwoven geotextile on the upper side and a
woven or nonwoven geotextile on the bottom. The
geotextile fabrics provides dimensional stability and
increased internal shear strength. When subjected to

liquid and moisture, the sodium bentonite swells to
form a very low permeability layer equal to that of
several compacted feet of clay.
GSE BentoLiner provides a cost-effective solution
to compacted clay for a wide range of applications
including ponds, landfill caps, containment
liners, and reservoirs.
