Finally, the low-permeability polyolefin coating is firmly attached, without the need of bonding with an additional
adhesion, e.g. glue, to the slit-film woven on Bentofix® X GCL types. This side can actually be installed up or down, depending
on the application’s need. The coating increases the GCL’s gas barrier performance, reduces root penetration, prevents bentonite
pipe under high-water gradients, decreases desiccation risk, guards against ion exchange, etc.
IN SHORT: Design safety increases, and service lives are extended.

1. The slit-film woven is the base for
the bentonite core and the fibre
reinforcement.
3. The nonwoven geotextile provides the
bentonite encapsulation and the high
internal friction characteristics.
2. High-swelling powder sodium bentonite as
the barrier component is uniformly distributed
over the slit-film woven.
4. The needle-punching (over 2 million fibres/m²)
with the fibres firmly bond these layers for a
long, sustainable service life.
5.
5. The polyolefin polymer-coated woven
provides resistance and a durable barrier.
Bentofix® X is a polyolefin polymer-coated GCL and exemplifies how modifications to GCL product design can be made to anticipate the
special challenges of a particular site. The woven fabric is coated with a low-permeability polymeric polyolefin coating to achieve
an immediate barrier prior to hydration and give the GCL several add-on values. Bentofix® X is an advance for GCLs in some specific
applications, such as waterproofing, oil and gas tank farms, landfill capping and cover systems or where high hydraulic gradients are present.
