Earth electrodes
For further information on FurseCEM®, please
contact the Furse sales office. A separate
datasheet is available.
Certain ground conditions make it difficult to
obtain a reliable earth resistance, whilst particular
installations may require a very low resistance. In
such cases, FurseCEM® provides a convenient and
permanent solution.
By adding FurseCEM® 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, FurseCEM® impregnated
concrete greatly increases the electrode’s surface area thus lowering its
resistance to earth.

Bentonite moisture retaining clay
Used as an earth-electrode backfill to reduce soil
resistivity by retaining moisture. The clay is a
sodium activated 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).
