Lynconite II Backfill Material
Lynconite II® is based on natural earth clay.
Special processing increases its electrical conductivity properties. With a resistivity of 0.6 ohms-meter, it is extremely beneficial for earth grounding applications.

The Ideal Grounding Backfill Material
Lynconite II is environmentally safe, meeting NSF Standard 60 requirements.
When mixed with water (approximately 13 gallons per 50 lb. bag), Lynconite II has a relatively low viscosity for approximately 45 minutes before it takes on gel like properties. It is poured into the hole before it gels, then solidifies, it adheres to the electrode and conforms to the hole’s dimensions, filling all voids, cracks and crevices, providing the best possible bond with the surrounding earth.
Unlike carbon based enhancement materials, Lynconite II does not place the grounding system in a corrosive environment. Lynconite II has a near neutral pH promoting a longer life span for any grounding system. Lab tests have shown a 120-year half-life for copper protected by Lynconite II, which is one of the reasons that the Lyncole XIT grounding electrodes can be warranted for 30 years, with a life expectancy of 50 years.
After the Lynconite II has set, it retains the water it was mixed with. If it is exposed to a desiccant (sun, wind), it may reduce some of its surface moisture and crack, but it will remain in a gel state a few inches below the surface.
