Our earthing method

Conductive concrete earthing.

A fourth-generation, maintenance-free grounding solution. Conductive concrete encases the electrode in a non-corroding matrix and holds permanently stable earth resistance — regardless of season, soil type or climate.

Technology

Conductive concrete, engineered for permanence.

A conductive aggregate mixed with cement at 2 parts aggregate to 1 part cement forms a conductive concrete with a resistivity of just 0.001 Ω·m at 150 psi.

That is orders of magnitude below bentonite, GEM compounds and salt-coke mixtures. The ultra-low resistivity lets fault current dissipate efficiently across the full electrode surface, while the concrete matrix protects the copper and steel from corrosion — the failure mode that quietly degrades chemical earthing over time.

Developed in the United Kingdom and in active use across Europe for over 60 years, this conductive-concrete earthing has been deployed across India for 15 years and more than 100,000 installations worldwide.

Salient features

Every property tuned for maintenance-free grounding.

Zero maintenance

No watering, no re-charging, no periodic servicing across its entire service life.

Ultra-low resistivity

0.001 Ω·m at 150 psi — orders of magnitude below bentonite, GEM and salt-coke backfills.

Seasonal independence

Conductivity is not tied to soil moisture. Earth resistance stays stable summer to monsoon.

Chemically inert

Neutral pH. Non-corrosive to steel or copper. Does not attack concrete or surrounding soil.

Electrode protection

Encases copper and steel electrodes in a non-corroding matrix, extending their working life.

Structural strength

Mechanical strength above Grade 25 concrete — can be integrated into the building structure.

The numbers

Resistance where it counts — measurably lower.

Resistivity is the single value that governs how well an electrode dissipates fault current. This conductive concrete is built to make it as low as the physics allows, and to keep it there.

Resistivity vs conventional backfills

Bentonite2–4 Ω·m
GEM compounds3–5 Ω·m
Salt / coke mixtures5–10 Ω·m

At 0.001 Ω·m, this conductive concrete sits orders of magnitude below bentonite, GEM compounds and salt-coke mixtures — enabling efficient fault-current dissipation across the full electrode surface.
