EARTHING

INTRODUCTION

Copper is the recommended material to use in earthing applications, whether below or above ground.

Materials used in earthing systems must be able to:

  • withstand mechanical damage
  • resist corrosion
  • provide a low impedance path to earth
  • carry the maximum fault condition for the application/installation

Our castings are high quality/high copper content complying to BS 7430 and BS 62561-1.

Additional to our range are UL listed copperbond earth rods and exothermic welding.

SOIL CONDITIONING AGENTS

Earth Points provide a convenient bonding point for a range of applications.

Bentonite Moisture Retaining Clay

Bentonite: Moisture Retaining Clay

Bentonite is used as a backfill to reduce soil resistivity. When mixed with water, it swells to several times its dry volume. This moisture content can be retained for a considerable time and further moisture can be absorbed during rainfall etc. Bentonite can be supplied in either powder or granular form.

Approximately 18 x 25kg bags create a volume of 1m³ (depending on soil and excavation conditions).

Material:
Sodium carbonate activated calcium montmorillonite clay. The product is a naturally occurring substance with no known ecological hazards, and can be disposed of as nonhazardous waste.

Granular:
Granular is the preferred option for filling trenches. The conductor is surrounded with Bentonite and then water poured over and mixed in the trench.

Powder:
Powder is the preferred product for pouring into bore holes, ensuring the mixture is of a thin enough consistency to reach the bottom of the bore hole.

Marconite Granulated Conductive Aggregate

Marconite® – Granulated Conductive Aggregate

Marconite® is a granulated conductive medium designed to replace the conventional aggregate in concrete and thereby provide a permanent medium with good electrical conductivity and high strength.

Marconite® concrete is touch dry within hours, but it will be several days before it is fully cured.

Marconite® is chemically inert with very low soluble sulphate content. It can be used with all conventional types of cement, as well as most proprietary resin-based cements, adhesives and gypsum plasters
