For further information on Marconite, please contact the Furse sales office. A separate data sheet is available. Marconite is a registered trademark of Marconi Communications Ltd., and is manufactured by PMC Holdings Ltd. - Conductive Products Division. Marconite is a unique product, developed by Marconi Communications Ltd. 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 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
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).
