example 1

[0063]Example 1 - GCL rectangles of approximately 100 cm2 were made by needling a conductive geotextile through powdered bentonite clay into a backing of a woven non-conductive geomesh. The perforated geotextile fibers are sealed to the backing geomesh by flame melting the protruding fibers. Conductive geotextiles were prepared by coating a nonwoven low weight (150 g / m2) PET geotextile with a solution containing a graphene dispersion to achieve a 2% weight percent loading of graphene on the geotextile. The electrical resistance of the conductive geotextile was measured to be 2000 ohm / square and kept in the assembled GCL.

example 2

[0064] Example 2 - The sample from Example 1 was placed beneath a waterproof geomembrane with purposely formed holes punched therein. The diameter of the hole is about 1 mm. When tested with a spark detector at approximately 15,000 volts, the GCL samples from Example 1 proved to be suitable electrical conductors to allow spark testing of waterproof geomembranes and holes were reliably detected.

example 3

[0065] Example 3 - The resulting 100 cm2 commercial GCL was used and a conductive geotextile was adhered to an existing nonwoven, non-conductive geotextile surface by needling through the existing GCL. The conductive geotextile was the same material used in Example 1. The samples were tested according to Example 2 and the same results as in Example 2 were obtained.

Abstract

An electrically conductive geosynthetic clay liner incorporating an electrically conductive textile graphene is disclosed.

Description

technical field [0001] The invention relates to the field of geosynthetic materials and their manufacture. In particular, the present invention relates to a geosynthetic clay liner comprising a geotextile having conductive properties. Background technique [0002] Geosynthetic membranes are waterproofing layers widely used as barrier layers in the construction of water retention facilities such as dams and ponds, or water diversion facilities such as drainage systems and waterways. These membranes can be deployed on a large scale and potentially cover thousands of square meters. These protective layers are commonly referred to as "geosynthetics" and can be waterproof plastic membranes and / or clay-containing composites. [0003] Clay lining is the traditional waterproofing method for water retention facilities. Modern composites of clay and geotextiles are known as "Geosynthetic Clay Liners" or "GCLs". They have better properties than traditional clay earthworks and can b...
