BENTONITE FOR GROUNDING SYSTEMS
In the ground, it can absorb the moisture in the surrounding soil, and this is the main reason for using it, as this feature helps stabilize electrode impedance throughout the year. It also features low resistivity -approximately 5 ohm per meter- and it is noncorrosive. Under extremely dry conditions, the blend may crack, decreasing the contact area between it and the electrode. Bentonite is thixotropic, so it is found as a gel when it is not moved or stressed. It is most often used as filling material when burying long rods. It is easily compacted and it bonds srongly
Applications & Uses
- Application Rate
The amount of bentonite to use depends on the type of soil, its resistivity and the type of grounding system (horizontal or vertical), but roughly 50Kg of bentonite are used for every m3 dug.
