SPECIFICATION FOR SINGLE ROD AND TRENCH
EARTHING (RADIAL EARTHING) INSTALLATIONS
UTILIZING LPI® GEL EARTHING TREATMENT
1. General Description
1.1 Installation of an earthing system which provides low impedance and low resistance earth.
1.2 Components:
Single Rod – Ground Resistance Improvement Powder (LPI GRIP), earth pit and earth
rod (copper bonded, solid copper, solid stainless steel).
Trench – Ground Resistance Improvement Powder (LPI GRIP), earth pit, copper earth
rod, copper tape and earth rod clamps.
2. Ground Resistance Improvement Powder (LPI GRIP) Properties
2.1 Shall contain a compound with a base electrolyte which, when mixed with other
compounds, produces an earth gel that provides:
2.1.2 A gelatinous mass within the surrounding soil that will not wash away.
2.1.3 A highly conductive mass, allowing for the efficient dissipation of electrical surges and
faults.
2.1.4 A highly conductive mass that is hygroscopic in nature and does not reduce, contract
or separate from the accompanying earth electrode.
2.1.5 A highly conductive mass which is not affected by seasonal rains and floods.
2.1.6 A highly conductive mass which does not contaminate ground water.
2.2 Once applied, the LPI GRIP shall provide for significant improvement in electrical
resistance values, with expected improvement of 5 to 20 times.
2.3 Unlike salt treatments, the stable compounds of the LPI GRIP shall not be corrosive in
nature and will therefore minimise corrosion of embedded earth electrodes.
2.4 Shall be suitable for all soil conditions, with particular effectiveness in difficult sites such
as rocky ground.
2.5 Greater quantities of LPI GRIP may be required to be applied to sites where excessively
high soil resistivity is found.
