Why Salt & Charcoal Chemical Earthing Fails — The Science of NEEC Crystalline Backfill
Understanding the corrosion chemistry of salt-charcoal pits and why environmentally inert NEEC crystalline compound guarantees 30+ year ground stability.

Adding common salt (NaCl) to an earth pit reduces soil resistivity temporarily by releasing sodium and chloride ions. However, chloride ions are aggressively corrosive to metal pipes, causing severe pitting and electrode disintegration within 24 to 36 months.

Eco-Friendly Non-Leaching NEEC Formula

ReErth's proprietary NEEC compound creates a permanent, conductive moisture-retentive envelope around the copper-bonded rod. It is non-corrosive, insoluble in water, and completely safe for surrounding groundwater tables.
