Description
Geoworks Granular Bentonite is supplied as a 25kg bag for use with Geoworks geosynthetic clay liner (GCL) systems.
It provides additional bentonite for jointing and detailing GCL installations where required, helping contractors order the associated installation material alongside the main liner rather than sourcing it separately.
For projects using Geoworks GCL 4500 Geosynthetic Clay Liner, the granular bentonite can be supplied as part of the same order and delivery.

What is Geoworks Granular Bentonite used for?
Geoworks Granular Bentonite is used as an additional bentonite material when jointing and detailing geosynthetic clay liner installations where required.
Can I use this with Geoworks GCL 4500?
Yes. This is the granular bentonite accessory we supply alongside Geoworks GCL 4500 Geosynthetic Clay Liner.
How much bentonite is supplied?

How much granular bentonite will I need?
The amount required depends on the GCL installation, jointing arrangement and individual project details. We recommend following the relevant installation or project specification rather than applying a generic coverage rate.

No. This is an installation accessory used alongside a geosynthetic clay liner. The GCL forms the primary low-permeability lining component of the system.

Additional bentonite may be required at certain joints, cut edges, penetrations, interfaces and other installation details, depending on the GCL system and project requirements.

Can I order the 25kg bags separately?
