LAMINATION

GEOfabrics is able to manufacture a broad spectrum of multilayer composite materials using a state of the art wide width lamination line. We are able to combine multiple components at a width of up to 6mts wide, thought to be the widest available globally.

Our process involves the passing of materials (normally thermoplastic) over a heat source to create a thin layer of molten polymer, following which the material is quickly pressed against its counterpart while still in its molten state.

Although the combinations available for Geocomposites are only limited to the imagination of the user, there are some common multiples that are effectively used on a wide basis:

Geotextile/Geonet Composites:
Geonets are often laminated to one or both sides of a Geonet. In this combination it provides a void space for the in-plane flow of liquids/gasses and the Geotextile provides the filtration/separation function.

Geotextile/Geomembrane Composites:
Geotextiles are laminated to one or both sides of a geomembrane to provide protection from both short term installation damage and long term strain. The main advantage of using a composite is the vastly increased installation speed.

Geotextile/Geogrid Composites:
Geotextiles are bonded to grids to provide an additional filtration function and allow for the separation of finer soils. It is recommended that a Geotextile with a high elongation be selected to ensure it does not inhibit the functionality of the Geogrids.

Geotextile/Polymer Core Composites:
A quasi-rigid plastic sheet: it can be extruded or deformed in such a way as to allow very large quantities of liquid to flow within its structure; it thus acts as a drainage core. The core must be protected by a Geotextile, acting as a filter and separator, on one or both sides.
