Cathodic protection

In cathodic protection, the anode groundbed is the arrangement of anodes in the ground or water and it provides the path for protective current to leave the anodes and enter to electrolyte.

Certain ground conditions make it difficult to obtain a reliable earth resistance, whilst particular installations may require a very low resistance. In such cases, Marconite provides a convenient and permanent solution.

By adding Marconite in place of sand and aggregate, to cement, a conductive concrete is formed. This electrically conductive medium has many applications in the electrical/construction industry, including RF and microwave screening, static control and of course earthing, for which it was specifically developed.

When used as a backfill for earth electrodes, Marconite impregnated concrete greatly increases the electrodes surface area thus lowering its resistance to earth.

No other product can offer the same benefits as Marconite in earthing applications.

Moisture retaining clay Sack weight

Part no

25kg CM015

Used as an earth-electrode backfill to reduce soil resistivity by retaining moisture. The clay consists largely of sodium montmorillonite, which when mixed with water swells to many times its dry volume. It has the ability to hold its moisture content for a considerable period of time and to absorb moisture from the surrounding soil (e.g.from rainfall).
